BLM 1 SMD 4 G

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BLM 1 SMD 4 G SM is a surface mount header connector designed for PCB integration. It features four positions with a 1.27 mm (0.050 inch) pitch, arranged in a single row. The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. The insulating body utilizes PA 4.6 GF material, providing UL94 V-0 flammability rating. Rated for 125 V AC nominal voltage and 500 V test voltage, it operates within a temperature range of -40°C to +163°C. The component supports wave soldering at 260°C for 10 seconds.

Headers, Receptacles, Female Sockets Feature Summary

• Surface mount design for automated PCB assembly
• Gold-plated contacts for corrosion resistance
• High-temperature resistant PA 4.6 GF insulating body

Headers, Receptacles, Female Sockets Applications

• General electronic circuit interconnections
• Signal routing on dense PCB layouts
• Industrial control module interfaces

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix variant required for your application, as Fischer Elektronik offers variations such as ECO or different contact counts. Confirm that the 1.27 mm pitch aligns with mating header specifications. Ensure the surface mount footprint matches the datasheet dimensions to prevent soldering defects during production.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, single-row header is needed for 4-channel connections. The 1.27 mm pitch balances density and ease of manual handling compared to finer pitches. Consider the gold finish if long-term reliability in corrosive environments is critical. Verify thermal tolerance requirements against the 163°C operational limit.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the BLM 1 SMD series of surface mount headers from Fischer Elektronik. The series provides various pin counts and configurations for board-to-board or cable-to-board applications. Similar parts include the BLM 1 SMD 4 G SM and other variants in the BLM family, distinguished by contact count and specific housing modifications.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 1.27 mm pitch, 4-position configuration, and surface mount package. Compatible alternatives include generic 1.27mm SMT headers from manufacturers like Molex or Samtec, provided they meet the 125V/500V electrical ratings and -40°C to +163°C temperature range.
