Contact Pins: Standard Configurations & Features

Posted by Jill Mayer on May 24, 2012, 4:39:00 PM

When purchasing contact pins, keep in mind they can be produced with many different features and configurations to best suit your application.  Additionally, the pins can be purchased with numerous types of plating, on a bandolier or as loose objects. 

Standard practice within quality contact pins are as follows:

  • Smooth transition between tip and body of the pin for lower insertion
  • Uniformity is essential. You should never have to worry about having contact pins at varying shapes and sizes because the tips are separated using a special process that ensures the highest level of uniformity for all of the tips on the pins.
  • The tips are recommended for use within a high-speed mechanical component to connect the printed boards and components into one unit.
  • Through the use of large reels, end to end contact pins are able to undergo additional processing, such as automatic insertion, with ease. The same reel these pins are wound on help prevent any bending that can occur.
  • Both ends can be accessed for polishing and finishing them off to your specifications.
  • Most standard contact pins are composed of brass, phosphor bronze, copper, nickel, stainless steel with a length of anywhere from .350 inches-2 inches. 

Beyond the features and configurations listed above, there are plenty of other options to choose from when it comes to purchasing contact pins.  Quality and uniformity is key, so strive for consistency and quality when finding a contact pin manufacturer.  Vision System Inspection can help achieve 100% consistency, but many manufacturers do not have these capabilities. If standards contacts will not work for you, custom contact pins are your next available option.
