The 640445-3: The friction lock secures the connector pair against vibration, and the shrouded 1-wall design protects the pins during handling. The UL94 V-0 glass-filled thermoplastic housing meets flame-rating requirements for equipment inside enclosures.
The post finish is also tin, compatible with standard solder processes.
The insulation height of 0.425" (10.80mm) provides clearance above the board. All 3 positions are loaded.
The 640445-3 mates with a corresponding MTA-156 crimp receptacle housing. The friction lock on the header engages with the latch on the receptacle. Confirm the circuit count and pitch match your application.
