BL 2 12 Z

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 2 12 Z is a PCB socket header featuring a stamped contact spring with a fork contact design. It accommodates a 0.635 mm separable pitch and contains 12 poles in a straight configuration. The component utilizes polysulfone glass-fiber reinforced (GF) insulator material for electrical isolation. Contact surfaces are constructed from CuSn alloy with tin plating to ensure reliable conductivity. The device supports a nominal voltage of 125VAC and maintains a current rating of 3A. It operates within a temperature range of -40°C to 160°C, ensuring stability across diverse environmental conditions.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix matches the required pole count and orientation. Confirm that the 0.635 mm pitch aligns with mating connector specifications. Ensure the operating environment remains within the stated -40°C to 160°C range. Check RoHS compliance requirements against project standards before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a straight, 12-pole socket header is required for PCB mounting. The choice depends on the necessity for a 0.635 mm pitch compatibility with existing cable assemblies. Consider the thermal limits of the polysulfone insulator for high-temperature applications. Evaluate the 3A current rating against the circuit load requirements to prevent overheating during operation.
