BL LP 4 38 S

Headers, Receptacles, Female Sockets Overview

The BL LP 4 38 S is a 38-position header connector manufactured by Fischer Elektronik. It features a 2.54 mm pitch and utilizes through-hole mounting for secure PCB integration. The contacts are forked, constructed from CuSn-alloy with selective gold plating on the contact surface and Ni+≥ coating on the contact sleeve. Designed for high reliability, the component supports an operating temperature range of -40°C to 200°C. The post length measures 0.110 inches (2.80 mm), ensuring appropriate engagement depth.

Headers, Receptacles, Female Sockets Feature Summary

• Forked contact type designed for mating with 0.635 mm diameter pins
• Selective gold-plated contact surfaces for enhanced conductivity and corrosion resistance
• Low profile construction optimized for compact electronic assemblies

Headers, Receptacles, Female Sockets Applications

• High-density PCB interconnections requiring robust mechanical stability
• Industrial control systems operating within extended temperature ranges
• Electronic assemblies utilizing standard 0.635 mm pin headers

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific application requires forked contacts rather than straight or socket types. Confirm that the mating pin diameter matches the 0.635 mm specification exactly to ensure proper engagement. Check that the operating environment stays within the -40°C to 200°C limit. Ensure the PCB layout accommodates the 2.54 mm pitch and through-hole requirements without interference.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a 38-position header with a 2.54 mm pitch is required. Choose this variant if the design mandates forked contacts for specific mating hardware. Consider the low profile dimensions if vertical space is constrained. Verify compatibility with the intended mating connector's pin diameter and plating specifications before finalizing the bill of materials.
