BLM 1 SMD 20 Z

Headers, Receptacles, Female Sockets Overview

The BLM 1 SMD 20 Z is a surface-mount female header connector manufactured by Fischer Elektronik. It features a 20-position configuration with a 1.27mm (0.050-inch) pin spacing. The contacts are constructed from CuSn alloy and tin-plated, while the contact sleeve utilizes Ni+46µm Sn plating. Designed for circuit points with an insert depth of 2.56mm, it exhibits an insertion force of 1.3 N and a drawing force of 1.1 N. The volume resistance is specified at less than or equal to 10 mΩ.

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the required contact count matches the 20-position specification. Confirm compatibility with the intended male header series, such as SLM or SLV, to ensure proper fit within the wide isolation body. Check that the application environment supports the tin-plated contact material and the specified volume resistance limits. Ensure the PCB layout allows for the required 2.56mm insert depth and handles the defined insertion and drawing forces during assembly.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 20-pin surface-mount interface is required with 1.27mm pitch. Consider its use if the design mandates a wide isolation body for robust male header alignment. Evaluate the tin-plated contact properties against environmental conditions. Verify that the mechanical requirements for insertion and drawing forces align with the assembly equipment capabilities and the target application's structural constraints.
