3M Connectors MDR Receptacles

3M MDR Boardmount Receptacle Plug Connectors are designed around a fine pitch ribbon-style contact for reliable electrical connection. With pin counts from 14 to 100, thru-hole, surface mount and press fit mounting styles, and multiple connector orientations, the 3M™ MDR boardmount product line offers engineers great flexibility when designing I/O interfaces. MDR Boardmount connectors feature either latch stands to allow latching of a quick-release backshell or threaded holes to allow thumbscrew attachment (with the proper hardware). Most MDR connectors feature 360 degree shielding around the entire interface to help improve EMI and RFI protection in sensitive applications. The integral dimples of the MDR metal shell ensure proper grounding of the shroud before mating, reducing the possibility of a destructive ESD event between the boardmount and wiremount connectors.
