Mill-Max

Mill-Max Mfg. Corp. is a vertically integrated manufacturer of precision-machined interconnect components, founded in 1971 by Roger L. Bahnik. The company produces machined contact pins and receptacles, PCB pins and solder terminals, IC sockets, board-to-board interconnects in through-hole and surface-mount styles, and spring-loaded Pogo Pin contacts and connectors rated for long cycle life and low contact resistance. It began by supplying gears and hobs for defense electronics, watches and parking meters, moved into machined pins and receptacles during the 1980s, and added in-house injection moulding. All engineering, sales and manufacturing operations are housed in a 150,000 square foot plant in Oyster Bay, New York, producing both standard catalogue parts and custom designs.
