This blog focus on board to cable connectors based on pogo pins, showcasing 10 reliability advantages to you. Analyze this solution item by item using real test data and structure comparison. Fundamentally optimizing the efficiency of engineering connections and system stability can help you make more reliable design decisions.
Anti vibration design ensures that board to cable connectors remain stable in harsh environments:
Under extreme working conditions, the stability of connected system determines entire machine reliability. If board to cable connectors can’t cope with continuous vibration and impact, the consequences can be serious. It will cause signal interruption, data loss, and even equipment shutdown. Traditional plug-in connectors lack dynamic buffering and are prone to failure due to mechanical fatigue or loose contact. The performance is not stable in high dynamic automotive, industrial robot, and aviation testing applications.
Board to cable connectors based on pogo pins have natural vibration resistance advantages. The internal spring of pogo pin has a typical elastic force of 0.5N-2.5N. Allow a travel buffer of 0.3mm-1.5mm, which can effectively absorb the energy caused by mechanical vibration. Based on sweep frequency vibration test data of 10-500Hz, contact impedance fluctuation of pogo pin connector is maintained within 10mΩ. Traditional rigid connectors can fluctuate by over 50mΩ. Stability has increased by over 400%. Based on MIL-STD-202, pogo pin was tested for 72 hours without contact interruption under 3-axis 20g peak vibration.
In addition, pogo pins in board to cable connectors can effectively prevent contact point friction fatigue. In multi axis impact test with 10 impacts per minute and 20,000 consecutive impacts, pogo pin maintained conductivity of >98%. The conductivity of traditional metal contacts decreases to around 75%.
Automatically compensate for displacement and improve assembly tolerance of board to cable connectors:
In actual assembly of board to cable connectors, displacement error is always a key variable that affects connection quality and yield. Traditional connectors often lack tolerance mechanisms. This can lead to slight misalignment, resulting in poor contact, stress concentration, and even welding failure. Board to cable connectors with pogo pins have automatic alignment and axial compensation capabilities. This can significantly improve the assembly tolerance of the connector.
Specifically, pogo pins can support an axial compression stroke of ± 0.3mm and a radial float of ± 0.15mm. It can effectively absorb offset between plate end and wire end caused by machining tolerances, thermal expansion, or operational errors. Johoty’s Brazilian client’s factory uses pogo pin structure board to cable connector. The customer’s assembly failure rate has decreased by over 72%, and labor hours have been saved by nearly 30%. This reduces the reliance on manual precision, making the connector more suitable for automated high-speed assembly lines.
Pogo pin adopts a spring guided structure, which mostly maintains a contact pressure of 30-90gf and provides dynamic compensation. Maintain stable connections in vibration or thermal shock environments. Enhance the robustness and industrial adaptability of board to cable connectors. For engineers, this structural innovation is a key lever for improving overall product reliability.
Self clean contact surface to ensure stable conduction of board to cable connectors even under low current:
The biggest challenge faced by board to cable connectors in <10mA is the small fluctuations in contact resistance at the connection points. This often leads to signal jitter, false triggering, or data loss. However, a solution validated by highly reliable scenarios is increasingly favored by European and American engineers. It is a board to cable connector with a pogo pin structure and self-cleaning contact.
The sliding friction between the pogo pin and the PCB pad during each insertion and removal creates a slight scratch. This can remove the micro polluted oxide layer and dust, and activate the metal activity on the contact surface through friction. It effectively maintains stable low contact resistance through this design. Actual test data shows that the fluctuation range of contact resistance in traditional static contact under 0.5V and 1mA conditions is as high as ± 15%. The board to cable connectors with self-cleaning design have a fluctuation of less than ± 2%, indicating a significant improvement in reliability.
After more than 10,000 durability tests, the contact impedance growth rate of this design is less than 5%, far superior to the standard shrapnel structure. This has become the preferred connection solution for engineers in medical equipment, precision sensing, and aerospace electronics that require extreme reliability.
The lifespan can reach 200,000 times, giving board to cable connectors an extended service life:
Industrial and medical equipment require high reliability, and lifespan of board to cable connector has become engineers’ core indicator. Traditional connectors have 5,000 to 20,000 lifespan, which is far from sufficient to meet long-term, maintenance-free requirements. High-quality pogo pin structure board to cable connectors have a compression life of up to 200,000 to 300,000 cycles. Based on actual lifespan testing of IEC 60512-5-2, they demonstrate a significant improvement in reliability on the order of magnitude.
Why is the difference in lifespan so significant? The pogo pin adopts a high elasticity alloy spring plunger, with a gold plating coating thickness of ≥3μin. Effectively reduce resistance growth rate, typically <15mΩ/100,000 cycles, to avoid contact failure caused by micro-motion wear. At the same operating frequency, traditional connectors exhibit significant contact instability after 10,000 cycles. And pogo pin type board to cable connector had a contact impedance fluctuation of <10% at the 200,000th time.
Johoty’s technology makes board to cable connectors suitable for high-frequency diagnostic instruments and automated probes.

For engineers pursuing ultimate durability and high-performance connectivity, this is a key turning point in redefining connector lifespan standards.
Multiple coating processes to enhance the corrosion resistance and conductivity of board to cable connectors:
The reliability of board to cable connectors in high-end engineering depends on their surface coating process. High quality finishing significantly improves the conductivity of connectors and extends their lifespan in corrosive environments. Conventional tin plated connectors experience corrosion after salt spray testing for 100 hours. Board to cable connector with a gold plating layer ≥0.76μm can operate stably for over 1,000 hours. Adopting a composite coating of palladium nickel (Pd Ni) and gold plating, the oxidation resistance is increased by nearly 5 times. They are suitable for medical equipment, outdoor sensors, and high humidity industries.
The gold plating process ensures a contact resistance of less than 10mΩ and more stable signal transmission. The palladium nickel coating provides excellent wear resistance and mechanical stability, making it suitable for frequent insertion and removal. High performance board to cable connectors commonly use multi-layer electroplating structures. They can fundamentally solve the problem of failure caused by corrosion.
Choosing board to cable connector with advanced finishing is key to ensuring long-term stable operation and precise signal transmission. In harsh environments, surface craftsmanship is not only about protection, but also the core of performance.
Modular integration enables flexible customization and compact interfaces for board to cable connectors:
Engineers often pay attention to the modularization of board to cable connectors in space constrained and highly integrated system design.

In high-frequency or long-term fixed connections, engineers focus on the mechanical reliability of board to cable connectors. Traditional connectors often use rigid plug-in structures, with insertion forces typically reaching 30-50N. This not only requires laborious operation, but also makes it easier to damage PCB pads or pin ports during long-term use.
In contrast, board to cable connectors with pogo pin compression structure significantly reduce insertion force. Only 3~5N, and maintain stable contact pressure, usually 50~100g/Pin. This flexible compression method showed a contact resistance fluctuation of less than 5% in 10,000 cycles of testing. There is no significant wear on the solder pads and connector terminals, greatly improving system stability and service life.
More importantly, pogo pin has an adaptive floating design during the pressing process. This can effectively absorb the deviation of docking tolerance and avoid poor contact caused by micro displacement. They are suitable for robot arms, automotive, and industrial applications with frequent vibrations and impacts.
