Mill-Max Omniball® Spring-Loaded Contacts include 4-pin spring contacts that offer various termination styles, such as surface mount, through-hole, and solder-cup versions. This Omniball product line offers an omnidirectional mating surface that allows for sliding into place in blind-mate or twist-lock applications. These contacts feature .030″ of vertical compression to ensure a quality electrical and mechanical connection. Mill-Max Omniball Contacts are ideal for horizontal and rotational connections since the wear is minimized at the point of contact between the plunger and the mating surface.
