BMA Connectors

Winchester Electronics' BMA Blindmate RF Connectors are designed to the interface dimensions of MIL-STD-348.

Winchester's BMA Blindmate connectors are designed for use in blindmate applications where multiple RF connectors need to be mated simultaneously. Typical applications include wireless base station infrastructure equipment, microwave subsystems, test and measurement, and military radar and satellite communication equipment.

This blindmate capability is accomplished by the slide-on, non-locking BMA interface - designed to allow a maximum of .020" radial and .060" axial misalignment. Winchester's BMA interface also includes a unique First-Make-Last-Break (FMLB) ground contact, which allows modular components to be plugged and unplugged or "hot swapped" in and out of a live system.
