BLY 4 70

Headers, Receptacles, Female Sockets Overview

The BLY 4 70 is a PCB receptacle connector from the Fischer Elektronik BLY04 series. It features a 2mm pitch spacing and a 2-row configuration with 70 positions. Designed for board-to-board connectivity, this through-hole header utilizes gold plating on contacts to ensure reliable signal transmission. The component accommodates specific conductor cross-sections and wire diameters within its design parameters.

Headers, Receptacles, Female Sockets Feature Summary

• Supports precise connectivity for conductors with a specified cross-section
• Utilizes inner contact springs made of CuBe-alloy for durability
• Features Ni+0,25µm Au surface treatment on contact springs
• Employs a 6-finger internal spring type for plugability

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnection systems
• Precision electronic device connectivity
• Through-hole PCB assembly applications

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the required pin count matches the 70-position specification exactly. Confirm the 2mm pitch requirement aligns with the target PCB layout. Ensure the through-hole mounting style is compatible with the manufacturing process. Check that the gold-plated contact surface meets the environmental and conductivity standards for the intended application.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a high-density 2-row connector is required for board-to-board links. The 2mm pitch offers a balance between density and manufacturability. Consider the CuBe-alloy spring material for applications requiring repeated mating cycles. Verify that the 70-pin capacity fits the circuit design without necessitating additional connectors.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the BLY04 series, which is engineered for precise connectivity with conductors having a Ø0.5 mm cross-section. The series accommodates wire diameters ranging from 0.4 mm to 0.56 mm. The BLY 4 70 specifically provides a 70-position interface, distinguishing it from other row lengths in the same product family while maintaining consistent technical characteristics.

Headers, Receptacles, Female Sockets Replacement Considerations

Consult official Fischer Elektronik documentation for confirmed substitute part numbers. Do not assume generic equivalents are compatible due to specific spring and pitch requirements.
