Spring-loaded contacts address divergent applications

MILL-MAX MFG Omniball family of spring-loaded pins includes one for low profile purposes and another that delivers improved stroke and higher current carrying capacity. Models 0945-1-15-20-06-14-11-0, a low-profile version featuring an 18% reduction in height from the original 0945 Omniball; and the 0845-0- 15-20-52-14-11-0, a larger style contact providing twice the stroke of the original product and a 40% increase in current carrying capacity. Device’s contacts are spring-loaded pins in which the traditional plunger has been replaced by a gold plated, brass ball. Devices are designed to simplify and improve the connections made between components which are mated together in a sliding or rotational motion rather than in an axial or vertical orientation. When engaged, the ball compresses and rolls, allowing the mating surfaces to make contact and then easily slide parallel to each other while spring force acts to ensure consistent electrical contact is maintained. This rolling action alleviates the concerns of connector damage such as binding, premature wearing and structural failure that may occur when using traditional plunger style spring pins in these types of applications.
