BL 4 34 Z

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 4 34 Z is a PCB receptacle designed for board-to-board connections. It features a 2-row configuration with 34 contacts and a 2.54 mm pitch. The component utilizes through-hole mounting for secure attachment to printed circuit boards. It is engineered with a nominal voltage of 125 V AC and a test voltage of 1500 V. The insulating body is constructed from PPS material, ensuring stability within an operating temperature range of -40°C to +200°C, with resistance to soldering heat at 260°C for 10 seconds.

Headers, Receptacles, Female Sockets Feature Summary

• Fork contact design stamped spring construction for reliable electrical connection
• PPS insulating body providing thermal stability up to 200°C
• Through-hole right-angle orientation for vertical board integration

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnects
• PCB receptacle applications requiring right-angle mounting
• Electronic assemblies operating in high-temperature environments

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix matches the required contact count and row configuration. Confirm that the PPS insulating material and fork contact design align with the target application's mechanical constraints. Ensure compatibility with standard through-hole assembly processes and verify that the 2.54 mm pitch fits the designated PCB footprint without modification.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a right-angle, multi-contact board-to-board interface is required. The 34-position capacity suits dense interconnection needs. Consider the 200°C thermal rating for high-heat environments. The through-hole method offers robust mechanical retention compared to surface-mount alternatives. Verify that the 125 V AC rating meets the system's electrical requirements.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Fischer Elektronik BL 4 series, which utilizes stamped contact springs with a fork design. This series is distinct from other Fischer connectors like the SL 4 headers or BL 10 female headers. The BL 4 series focuses on robust, right-angle receptacles suitable for demanding board-to-board connections.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes require matching the 34-position count, 2.54 mm pitch, and right-angle through-hole form factor. Verify that alternative components maintain the same PPS insulation class and fork contact geometry to ensure mechanical and electrical interchangeability.
