Spring-loaded connectors come with pointed or flat tip plungers

MILL-MAX 854 (Single row) and 855 (Double row) series .050” (1.27 mm) pitch spring-loaded connectors, now available with either pointed or flat tip plungers, provide solutions for making optimal connections across a range of applications. The standard full radius plunger tip, found on most spring-loaded pins, is suitable for use in many cases, however, there are situations in which a different plunger tip shape can be advantageous. Flat tip plungers improve surface area at the point of connection, distributing the electrical charge and delivering more efficient heat dissipation. Typically, finer pitch connectors are used in compact assemblies and these improvements in heat management can reduce the total amount of heat generated in a circuit. Flat tip plungers allow for greater tolerance misalignment of mating surfaces, as well as consistent contact during lateral movement of the mating components because the larger pin tip surface stays in contact through a greater range of motion than a round tip. This can be vital in applications that are subject to motion and vibration, such as wearable devices for medical purposes.
