Overview
The B5743-234-M-T-W is a male header connector from the Datamate L-Tek series by Harwin Inc. It features 34 positions arranged in a dual-row configuration with a 0.079-inch (2.00 mm) pitch and row spacing. Designed for vertical through-hole mounting, it utilizes a shrouded four-wall housing and pin-lock fastening. The contacts are gold-plated phosphor bronze pins with a tin-lead column finish. Rated for 800VAC/DC and 2.2A, it operates within a temperature range of -55°C to 125°C using UL94 V-0 rated polyester insulation.
Feature Summary
- Features a shrouded four-wall design for secure alignment and protection
- Utilizes pin-lock fastening mechanism for reliable connection retention
- Constructed with gold-plated phosphor bronze contacts for durability
- Supports vertical through-hole termination for board-to-board or cable applications
Applications
- Board-to-board interconnections requiring high density
- Cable-to-board connections in industrial equipment
- Electronic assemblies demanding robust mechanical locking
- High-voltage signal transmission environments
Procurement Notes
Verify the specific suffix 'W' against official Harwin documentation to confirm material or coating variations compared to standard variants like 'T-1'. Ensure compatibility with mating female sockets from the same Datamate L-Tek family. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region.
Selection Notes
Select this component when a 34-position male header with vertical orientation is required. Ensure the application supports through-hole soldering processes. Verify that the mating interface accommodates the 2.00 mm pitch and shrouded design. Consider the operating temperature range and voltage ratings to ensure they meet system requirements without exceeding the 800VAC/DC limit.
