The 87024-645LF: The BeCu spring maintains contact normal force through temperature cycling and repeated mating — a meaningful advantage in a 90-position connector where a single weak beam opens a signal path. The housing is glass-filled thermoplastic rated UL94 V-0, natural colour.
RoHS compliant.
In a board-to-board application that is mated during manufacturing and rarely cycled in the field, this plating far exceeds the required cycle life and provides corrosion resistance in industrial environments.
Yes — the connector includes a board guide feature that aligns the receptacle with the mating header during assembly, reducing the risk of stubbing or bending contacts on a 90-position connector.
Listed for general purpose, industrial, and telecommunications applications. The UL94 V-0 housing and BeCu contacts suit equipment that must meet flame-rating requirements and operate in environments with moderate thermal cycling.
