Custom Pogo Pin Connector Can Solve Connection Challenges
Johoty rarely defines a spring loaded connector or interconnect by one specification. We can design the custom pogo pin connector to carry meaningful current while occupying very little PCB area. You can repeatedly dock and your clients won’t need to align the male end and female end precisely.
That is why Johoty approaches custom pogo pin connector as a perfect system-level engineering task. With this, our clients can maintain stable contact during the vibrates, shifts or accumulates dimensional tolerance. Johoty can also help clients integrate power, ground, sensing and communication signals/data inside one compact interface.
Limited Space:
Many clients have the restriction on board area or product thickness. Johoty can evaluate contact diameter, compressed height, and pitch together. Also, we can evaluate pin arrangement, housing geometry, and termination method together. We don’t optimize one dimension at the expense of dimensions else.
Power in a Compact Interface:
Johoty doesn’t determine the current by a marketing label only. We design it based on contact geometry, conductive materials, and contact resistance. We also customized our pogo pin connector based on plating, temperature rise, life cycles and pin counts. For demanding power, Johoty can evaluate the electrical path as part of custom pogo pin connector structure.
Repeated Docking:
Clients need connectors to experience frequent mating in charging docks, handheld devices, robotic systems, removable modules and service interfaces. To solve clients’ challenges, Johoty always consider spring force, working stroke, and contact geometry together. We also focus on target design, plating and mechanical guidance together.
Imperfect Alignment:
There always are mechanical tolerances in real products. This can create axial, lateral or angular offset during PCB placement, enclosure molding, assembly variation and user-controlled docking. Johoty can properly engineer spring-loaded interface with compliant contact travel, target geometry and mechanical guidance for more forgiving connection.
Harsh or Exposed Environments:
Many clients often encounter water, dust, sweat, cleaning, vibration or temperature changes and need to protect the connectors. Johoty can design the custom pogo pin connector perfectly from the beginning rather than treated as an afterthought. Clients can get IP67 or IP67 waterproof pogo pin connector for outdoor, seawater, automotive, and so on.
Mixed Electrical Functions:
More and more clients ask for power, ground, low-current signal, detection and communication contacts in one connector. Johoty can develop custom pogo pin connector to organize these functions within one mechanical interface. We always consider current paths, spacing, sequence and manufacturability in mind together.
Custom Pogo Pin Connector Around Your Mechanical and Electrical Architecture
Johoty never considers the custom pogo pin connector as more than changing pogo pin count only. We can design a custom pogo pin connector around the mechanical dimensions and functional requirements.
Many clients’ projects often begin with a complete engineering drawing or an existing connector. They always need improvement, PCB layout, housing model and mounting, or optimized performance requirements. Johoty can translate those constraints into a manufacturable spring loaded connector.
Contact Architecture:
Johoty can flexibly configure pogo pin number and arrangement according to the electrical functions of your device. Clients can get the linear, dual or multi-row, circular, asymmetric and application-specific layouts to match available space and mating.
Johoty can perfectly arrange power, ground, sensing and signal positions according to clients’ intended electrical architecture. We never force every pogo pin or contact pin to perform the same function.
Pitch and Density:
Johoty can select the right pitch according to contact size, electrical isolation, manufacturing tolerance and available PCB area. We can help our clients to achieve various pitches of 1.00mm, 1.27mm, or other custom pitch.
We can balance miniaturization with sufficient mechanical stability and production consistency for dense layouts, connector geometry. On pogo pin distance, pitch, height and working stroke, we can help clients with perfect solutions.
Working Height and Stroke:
All clients always value the working stroke and spring force to achieve a controlled compression. In fact, it is also important for client’s devices. Especially, for those structure restrictions, ≥0.10mm working stroke can help client solve the connection compensation and stability.
Johoty can tailor free height, working height and max compression in our custom pogo pin connector. This will match the distance between mating surfaces and the tolerance stack of the complete assembly.
Spring Force:
For custom pogo pin connector, Johoty customizes spring force to ensure contact stability, total mating force, wear and user experience. Many clients require <5% spring force attenuation after 100,000 life cycles, or continuous compression during life cycles. Yes, it is achieved.
Johoty can configure spring force as a system according to pogo pin count, required normal force, stroke and mechanical design. Because the increasing force at each individual pogo pin can dramatically increase the total force of complete connector.
Plunger Tip and Target Geometry:
Johoty can provide clients with >10 types of plunger tips, including flat, rounded, pointed, crown, and so on. Each type of plunger tip can perfectly match the target surface, required wiping behavior, contact area and application. Clients can also specify the plunger tip shape or refer to our proposal for the projects.
We always consider the mating target and the plunger tip together for our custom spring loaded connector whenever possible.
Materials and Plating:
Many clients ask custom pogo pin connector for outdoor, seawater, automotive, and so on. To meet client’s requirements, Johoty can accurately select the base materials and surface finishes. Including nickel, gold, Pd, Pd, silver, Ru, Rh as pogo pin plating, or composite plating. We can customize these solutions for conductivity, mechanical wear, corrosion environment, contact resistance and expected mating life.
We can also specify gold plating thickness and underplating to guarantee actual performance instead of only appearance.
Housing Design:
Johoty customizes the plastic housing much more than appearance only. We need to complete IP67 or IP68 waterproof, smooth mounting or fixation in devices, or high speed/frequency with EMI shielding.
Johoty can perfectly customize plastic housing around the product architecture. We don’t require client to redesign the product enclosure around a standard connector. Then, our clients can get perfect pin positioning, insulation, and mechanical guidance. And, they can get correct polarity, mating orientation, retention, sealing and integration with the enclosure.
PCB and Assembly Integration:
Johoty can flexibly design the custom pogo pin connector to match client’s product architecture, including round, rectangular, and special shapes. On mounting, we have custom solutions for SMT, through-hole, soldered, right-angle, cable-integrated or other application-specific termination structures.
Our objective is not simply to manufacture the custom pogo pin connector only. Johoty is to make the connector practical to assemble into the final product.

Many clients ask for special termination, housing geometry, and mating life cycles, we can achieve them. For clients’ applications, Johoty can also customize it according to mechanical alignment, polarization, retention, sealing, or magnetic assistance.
Contact:
In medical, aerospace, smart wearable, clients always emphasize plunger diameter and profile, spring force, barrel diameter and working stroke. Because clients need to get the expected electrical performance, available package space and mechanical duty.
Johoty always customize identical mechanical dimensions and electrical parameters for different contact functions. Our custom pogo pin connector often uses dedicated contact or positions for power, ground, sensing and signal functions.
Mechanical:
Clients have different design concepts for different project. Johoty must flexibly offer the housing around client’s PCB, enclosure, panel or docking structure. We aren’t allowed to force client’s industrial design around a predefined connector outline.
We can offer our clients straight, right-angle, recessed, and surface-mount. When clients need through-hole, soldered, wire-terminated or application-specific mounting, we can follow up. For the expected mechanical alignment, we can also offer reliable custom pogo pin connector for lateral or angular mating variation.
Environmental:
More and more clients design equipment for environments exposed to moisture, dust, cleaning processes or outdoor operation. So, Johoty needs to customize the sealing together with housing geometry, mating compression and materials based on injection molding.
Finally, Johoty’s clients can get an application-specific interface with IP67 waterproof or IP68 waterproof after validation of the final assembly.

Reliability and Proven Verification of Custom Pogo Pin Connector
Custom Pogo Pin Connector Contact Performance Begins at the Material and Plating
Many clients know a pogo pin is a moving electrical contact. They also know pogo pin conductivity, wear, corrosion, spring stability and contact resistance are influenced by the materials and surface.
We can customize the perfect plunger according to the required electrical load, mechanical duty, mating frequency and environment. Johoty often uses brass for the conductive contact according to clients’ required balance of conductivity, hardness and mechanical performance. We also use spring materials according to clients’ required force, operating temperature and life cycles.
Johoty can also define the gold plating or composite coating by actual applications instead of a generic thickness table. Our clients can get a corrosion-resistant contact surface for low and stable contact resistance by gold plating. And, they can get the perfect adhesion, diffusion resistance and wear behavior by underplate and base material.
We always evaluate contact surface, plating thickness, plunger geometry and target material as one tribological system for repeated mating. We select housing materials according to dimensional stability, dielectric requirements, temperature exposure, molding geometry and assembly process.
Johoty carefully considers spring material by temperature, compression and exposure to the intended environment for IP67 or IP68. So, we always emphasize the materials of custom pogo pin connector as an important part of our perfect design. Please note, it’s not an a purchasing decision after geometry is frozen.
