Your Reliable Pogo Pin Manufacturer

A Pogo pin or spring loaded pin is a connector widely used in modern electronics. Dongguan Promax is a professional pogo pin manufacturer. Experts in the field of high precision, unique, intelligent pogo pins, confident in the design, quality, manufacturing technology, service, and delivery! 

Ensure > 95% sample FPY and > 99% volume production FPY. (FPY: First Pass Yield, is the quality indicator)As the world’s leading pogo pin manufacturer, Dongguan Promax offers excellent ODM services and competitive prices.

Promax’s products are widely used in consumer electronics, new energy, chip testing, communications, smart home, medical equipment, and other fields.


Production lines of Spring Loaded Pins and Spring Loaded pin Connectors are conducted in dust-free workshops.  

When the plunger pin, locking pin, and spring are assembled, the impedance is tested by an automatic spring impedance tester.  

This will be followed by CCD, aligner, manual pressure, crimping, and full inspection. A spring loaded pin has multiple testing steps to ensure that each pogo pin is of high quality.

How about our products’ Cpk?

Our precision is second to none, thanks to our rigorous analysis of NC4891 sample size data. With a Cpk value of 0.98~1.12, we maintain a failure rate of just 0.5‰~0.9‰.In other words, only 5~9 wrong products emerge from every ten thousand. It’s an impressive feat, and we’re not done yet.
We’re committed to mastering the complete quality control system, pushing towards our ultimate goal of Cpk1.33. With us, you can trust that your products will be nothing short of exceptional.

Gage R&R (ANOVA) for Press Fit

We leave nothing to chance when it comes to quality control. For our press fit, we analyzed 100 pressure data points using GR & R method. To ensure thorough testing, we enlisted three technicians to test the reproducibility and repeatability of the press fit across 10 different products.
Our commitment to precision is unwavering, and our quality control measures are among the most rigorous in the industry. When you choose us, you’re choosing excellence. 


What is pogo pin?

Spring loaded pin is an electrical connector structure used in modern electronic applications. They are more durable than other electrical connectors.

The name spring loaded pogo pin comes from the pin’s resemblance to a pogo stick – the integrated helical spring in the pin applies a constant normal force against the back of the mating receptacle or contact plate, counteracting any unwanted movement which might otherwise cause an intermittent connection.

What is pogo pin's inner structure?

A basic spring loaded pin consists of 3 main parts: a spring loaded plunger pin, a spring loaded locking pin, and a spring.

Different design concepts, such as Bias Tail, Back Drilling, Ball, T-pin, or Coaxial, are required for customers’ different applications.T-pin/Ball/Coaxial designs can handle high currents up to 15A and have a resistance of <30mΩ.

Bias Tail can improve pin stability with a current of <3A and resistance of <30mΩ. Back Drilling is suitable for minimal space design, can save design space, and has a current of <1A and resistance of <200mΩ.

What is Pogo Pins' Working Status?
  • Free Height:   is no load height, full extension height of spring
  • Working Height:  is the ideal load height for spring
  • Maximum Load Height: is the maximum load height of the spring, usually, contacting the end of the barrel
Pogo Pins' Designs
  • Spring loaded pin, because barb on the barrel, very stable after mounting onto the housing
  • Stopper on the bottom of the Spring Loaded Pin, a very strong fix into the housing too
  • In the range of ±10°, no dropping for the Spring Loaded Pin life cycle, but, when the angle is 15°, the life cycle will drop accordingly
Pogo Pins' Life Cycles
  • At Dongguan Proma, the Spring loaded pin life cycle is in the range of 10,000 to 100,000 times
  • Mechanical life cycle:  maximum working times to ensure spring force in spec
  • Electrical life cycle: maximum working times to ensure contact resistance in spec
