This specification defines the general performance parameters and test requirements for the Pogo pin family of products.
The dimensions correspond to the product drawings.
2.2 Materials and plating
The body is a brass alloy, and the nickel-plated outer layer is covered with a gold-plated layer. The thickness of the nickel layer and the gold-plated layer varies depending on the application, but the nickel layer needs to be larger than 60 uin and the gold plating is larger than 4 uin.
Plunger is a brass alloy. The outer surface of the nickel-plated nickel-plated layer is covered with gold. The thickness of the nickel layer and the gold-plated layer are different depending on the application. However, the nickel layer needs to be larger than 60uin and the gold plating is larger than 16uin.
Spring is stainless steel, but also can be electroplated steel wire. Plastic is high temperature nylon plus 30% glass fiber.
