B5743-234-M-T-1

Overview

The Harwin B5743-234-M-T-1 is a Datamate L-Tek male header connector featuring 34 positions arranged in a dual-row configuration. It utilizes a 2.00mm pitch and employs vertical through-hole termination for secure board mounting. The contacts are constructed from phosphor bronze with gold plating on the mating surfaces, ensuring reliable conductivity. Designed for robust industrial applications, it supports a rated voltage of 800V AC/DC and a current capacity of 2.2A per contact. The housing is made of black glass-filled polyester with UL94 V-0 flammability rating, operating within a temperature range of -55°C to 125°C.

Feature Summary

• Features pin-locking latches that require tooling for engagement, providing high mechanical retention and vibration resistance.
• Incorporates four-wall shielding shrouding to ensure precise alignment and prevent mis-mating during connection.
• Utilizes circular contact geometry with gold-plated mating surfaces for durable electrical performance.
• Supports both board-to-board and cable-to-board interconnection styles within a compact vertical profile.

Applications

• Industrial control systems requiring secure, latch-locked connections
• Test and measurement equipment needing high-reliability signal paths
• Automotive electronics subject to vibration and harsh environments
• Medical devices demanding stable power and data transmission

Procurement Notes

Verify the specific suffix 'T-1' against the manufacturer's latest datasheet to confirm orientation and latch type. Ensure compatibility with required locking tools for installation. Check RoHS compliance status as manufacturing processes may evolve. Confirm PCB footprint dimensions match design requirements before finalizing procurement orders.

Selection Notes

Select this component when high mechanical security is critical due to its unique pin-locking mechanism. The dual-row layout maximizes density while maintaining 2mm spacing. Consider the need for specialized insertion tools during assembly planning. Evaluate thermal management needs given the 2.2A current rating per contact in enclosed spaces.

Part Context

This part belongs to the Datamate BS series, a British Standard 2mm connector system by Harwin. It is designed for high-density interconnects where reliability under stress is paramount. The L-Tek variant offers enhanced durability compared to standard versions. It complements matching female sockets and accessories within the same ecosystem for complete system integration.

Replacement Considerations

Direct substitutes include other Harwin Datamate BS headers with identical 34-position counts and vertical orientation. Verify latch mechanism compatibility if replacing with non-Harwin equivalents. Ensure pitch and row configuration match exactly to maintain PCB footprint integrity without redesign.

FAQ

What tooling is required for this connector?

Specialized insertion tools are required to engage the pin-locking latches, ensuring proper mechanical retention and preventing damage during assembly.

Is this connector suitable for high-vibration environments?

Yes, the pin-locking feature provides superior vibration resistance compared to standard friction-fit connectors, making it ideal for automotive and industrial applications.
