BLY 1 4

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BLY 1 4 is a precision-engineered stamped contact spring designed as a fork contact for a 0.635 mm square profile. This component features a tin-plated surface finish and is constructed from a CuZn-alloy base material. The contact spring utilizes a gold-plated surface, while the inner contact spring is made of CuBe-alloy. It is specifically designed for precise connectivity with a conductor cross-section of Ø0.5 mm and accommodates wire diameters ranging from 0.4 mm to 0.56 mm.

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific variant matches the required 0.635 mm square profile compatibility. Confirm that the supplier provides components with the specified CuZn-alloy construction and gold-plated contact springs. Ensure the ordering documentation explicitly references the BLY 1 4 designation to guarantee the correct inner CuBe-alloy spring composition and tin-plated sleeve specifications are met.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a fork contact design is necessary for a 0.635 mm square profile interface. The choice is driven by the requirement for a CuZn-alloy body combined with a gold-plated contact spring to ensure reliable conductivity. Consider the specific accommodation for 0.4 mm to 0.56 mm wire diameters and the use of a CuBe-alloy inner spring for mechanical resilience in high-cycle applications.
