  • Johoty Story.  Some feedback from foreign customers, many domestic suppliers fail to understand the technical info sent by the R&D in electronics, or can’t meet the expected results before customers start to do tests or DOE, and thus can’t design and produce all kinds of precision components that customers want to get indeed.
  • For example, the pogo pin material is brass, and its outer diameter is only 1.27mm, how to realize a continuous 25A high current?
  • For example, how do customers believe that rating current will be able to pass the desired current value before they place an order?
  • Although there will be a 100% full inspection before shipment, we always simulate it based on our strong electronic R&D and software development, finally, customers believe that we can realize it and meet targets.

Customer Cases

Quality Requirements

  • An U.S. customer sent Johoty a few pogo pin samples, requesting the design of pogo pin that are continue stabilized at a high current of 25A for over 3 minutes, 
Johoty Pogo Pins_55503_Solder Cup Pogo Pins
  • The pogo pin shape is solder cup type. Spring force is 150gf.

Price Requirements

  • A higher price is acceptable for sample order, will have to restore to normal price when request mass production goods.

Services. – Analysis

  • Based on analyzing the pogo pins samples, the current size (go through only φ1.3mm plunger) and material of brass,
  • It is almost impossible to pass a high current of 25A, much less get a continuous and stable high current of 25A.

Services. – Study

  • Based on our design experiences, brass can’t meet target at all, suspected BeCu is okay.
  • So, we adopted 2 steps, the first was to estimate BeCu rating current by simulation software based on the dimensions of samples, the preliminary conclusion is okay.

Services. – DOE

  • The second was to test temperature rise of new samples, that is, we produced a few new samples made of BeCu,
  • And found each sample can go through 25A for 3 minutes, or 30A in short seconds, and the temperature raise is less than 20℃.


  • We proposed customer the drawing with new material of BeCu, and attached all studies and DOE.
  • Finally, we got approval from customer, and helped customer produce 50pcs samples, as well as mass production goods later.



We sent the 50pcs samples to our customer by DHL. Lead time is 3 weeks. Sure, our customer was very satisfied at the samples, mass production goods, and Johoty.

Services, Solutions

Quality Requirements

  • A French customer sent us an uncompleted 3D of 6pin connector, including 5pcs short pogo pins, 1pcs long pogo pin, and 1pcs housing.
Johoty pin connectors_11_5 pin connector


  • Request was to assembly total 6 pogo pins into the housing.
  • The current problem was that customer couldn’t fit in it by 3D at the current size,
  • and it would be potentially unproductive to hardwire it.

Services.  – Analysis.

  • We found the 6-pin connector was really difficultly assembled well based on current dimensions.
  • We tried to fine tune barrel size of pogo pins and inner hole diameter of the housing in change of 0.1mm basic.

Services:  – Study

  • Because barrel OD was φ1.80 mm of long pogo pin, φ1.50mm of short pogo pin, and, the thickness from inner wall to outside was only 0.28mm for long pogo pin, which had potential risks to broke the housing,
  • At the same time, sufficient plunger OD was required of the long pogo pin for its actual application. That is, it was not good to greatly reduce φ1.80mm yet.


  • We suggested customer a 0.4mm thickness from 0.28mm for long pogo pin, which would securely hold the long pogo pin without any production risks.
  • Finally, we got the green lights from customer to finalize the drawing.


Price Requirements

  • Johoty always provides affordable price, and, he is our long-term customer.
Pogo Pins_66608_SMT Pogo Pin Johoty



  • It is very simple.
  • We ship 200 sets of samples to the customer by the customer’s DHL accounts.
