Double Ended Pogo Pin Advantages:
Double ended pogo pin for ultimate electrical performance and ultra-low contact resistance
Engineer challenges: Engineers often need to test sensor signals with weak signals, high-frequency signals, or carrying high currents. But if the contact resistance of the connector itself is unstable, it will become a killer of signal integrity and power loss. Traditional connection schemes suffer from resistance fluctuations caused by oxidation, coating wear, and uneven contact pressure. It will directly introduce noise, cause voltage drop, and affect testing accuracy or system energy efficiency.
Johoty’s solutions:
Precise plating process: Johoty uses high hardness gold alloy coating on zirconium copper substrate, providing excellent conductivity. It also has extremely strong wear resistance and corrosion resistance. After 10,000 connections, the contact interface can still maintain low and stable contact resistance.
Optimized internal structure: Finite element analysis optimized SUS631 spring and precision CNC produced plunger and barrel. Minimize current transfer impedance inside. The plunger tip features a specially designed spherical or coronal structure. Achieve maximum effective conductive area with minimal physical contact area. Reduce the contact resistance to 10mΩ.
Value: Engineers will obtain more realistic signal acquisition and higher testing yield. Lower energy consumption and longer battery life.
Double ended pogo pin has excellent mechanical durability and plug-in life
Engineer challenge: Automated testing production lines, frequently replaced modular products, or equipment that requires repeated calibration. The plug-in life of connectors directly determines the maintenance cycle and overall reliability of the system. Ordinary connectors may experience spring fatigue and coating peeling after 10,000 connections, leading to connection failure.
Johoty’s solution:
High performance spring material: Choose piano steel wire SWP-B or SUS631 wire imported from Japan or Switzerland. They need to go through strict stress relief and heat treatment processes. The spring can maintain <1% elasticity attenuation after 100,000 compressions, with super strong rebound force and fatigue resistance.
Precise coaxiality and smoothness control: The barrel inner and outer walls of the Double ended pogo pin have extremely high smoothness. The coaxiality tolerance control of <0.02mm ensures smooth and unobstructed sliding of the plunger in 10,000 cycles. This can minimize the generation of particulate matter and internal wear to the greatest extent possible.
Value: Johoty’s double ended pogo pin has a lifespan of 10,000 to 500,000 cycles. This greatly reduces the downtime of production testing equipment. Providing a never loose connection experience for consumer products, significantly enhancing the quality and durability of end products.
Superb environmental adaptability and robustness
Engineer Challenge: The equipment needs to operate in industrial environments with vibration, impact, high temperature and humidity, or the presence of corrosive gases. The performance fluctuation or failure of connectors is one of the main causes of system failures. Engineers need a robust connection solution that can withstand these harsh conditions.
Johoty’s solution:
Comprehensive sealing design: Johoty can integrate O-rings on the exterior of the barrel for panel sealing, with advanced IP67/IP68 internal sealing technology.

FAQ
Concerns: Engineers are concerned about the impact on testing accuracy and equipment reliability in data transmission, RF testing, or high current transmission scenarios. Because the impedance fluctuations, heating, and mechanical fatigue of the connector itself can lead to signal integrity degradation or power loss.
Johoty’s solutions：
Ultra-low and stable contact impedance:
Material: Plunger and barrel are made of highly conductive beryllium copper alloy C17200, with extremely low substrate resistance. The key contact surface is coated with thick gold ≥0.2μm, and can be optionally equipped with precious metal alloy rhodium ruthenium. Effectively suppress surface oxidation and reduce contact resistance to ≤20mΩ. The impedance fluctuation range is extremely small during the lifecycle.
Performance: This low impedance can significantly reduce thermal effects (P=I ² R) when transmitting currents greater than 5A. Avoiding performance degradation caused by temperature rise ensures the integrity of high-speed signal transmission.
Excellent mechanical lifespan and contact force maintenance:
Precision structure and mechanical optimization: using an integrated spring and high concentricity precision plunger and barrel combination. Eliminate internal separation points that may exist in traditional modular structures. After stress release and fatigue optimization treatment, the contact force attenuation of the spring is strictly controlled within<10% after 100,000 cycles.
Performance: In 100,000 tests, Johoty’s double ended pogo pin maintained a contact force of 5gf-1,000gf on the UUT. Avoid poor contact or virtual connection caused by force attenuation, and ensure continuous and stable electrical connection.
Concepts: Arranging a large number of connection points in a limited space requires pogo pins to have extremely small footprint and height. At the same time, it is necessary to address the possibility of short circuits that may occur during vibration or misalignment due to close spacing.
Johoty’s solutions：
Millimeter level miniaturization and high-precision manufacturing:
Size range: Available in outer diameters ranging from 0.50mm to 10.00mm, and capable of achieving dense layout with center to center pitch as small as 1.00mm.
Strict tolerance control: The overall coaxiality tolerance of plunger and barrel is controlled within ± 0.03mm. During docking, even with slight angular tolerances, accurate alignment can be achieved to prevent pin jamming or unilateral wear.
Comprehensive insulation and protection design:
Insulation housing: Optional high-performance engineering plastic PEEK insulation outer housing can be used to wrap the entire barrel externally. This material can withstand voltages of 500VAC and above, excellent high temperature resistance, and mechanical strength.
Performance: The insulated housing fundamentally eliminates the possibility of short circuits between adjacent double ended pogo pins due to metal shell contact. Very effective when misaligned or subjected to lateral forces. Johoty’s double ended pogo pin has become the safety first choice for high-density, high-voltage applications.
Concerns: Equipment can directly threaten the continuity of electrical connections when subjected to vibration, shock, temperature cycling, as well as dust and moisture. This may cause mechanical components to get stuck or corrode.
Johoty’s solutions：
Excellent anti vibration and anti-impact performance:
Dual spring and redundant contact design: Some high-end models adopt dual independent spring systems or multi contact needle designs. When a spring temporarily becomes unstable due to vibration, another spring or contact can immediately take over to maintain the continuity of the circuit path.
Verification standard: Double ended pogo pin design verification strictly follows MIL-STD-202G for vibration and mechanical impact testing. Within the specified frequency and acceleration range, there is no instantaneous change in contact resistance.
Advanced anti jamming and self-cleaning technology:
Guidance and sealing design: The plunger adopts a sloping or spherical guidance design for easy blind insertion and alignment. At the same time, a micro maze or sealing structure is designed inside the barrel, which can effectively prevent dust and flux residue from entering.
Self-cleaning coating: Precious metal coating provides low resistance, and Johoty’s double ended pogo pin has a self-cleaning effect. It can wear through the slight oxide film or pollutants formed on the surface during repeated connections, keeping the contact interface clean. Fundamentally prevent contact failure or jamming caused by pollution.
Environmental Durability Certification
Standard compliance: Johoty’s double ended pogo pin can pass IP67, ensuring dust resistance and short-term immersion. At the same time, the materials and processes meet the stringent requirements of ISO 11452 for temperature, humidity, and chemical corrosion.
