Overview
The B5743-218-M-L-1 is a Datamate L-Tek header connector manufactured by Harwin Inc. It features an 18-position male pin configuration with a 2.00mm pitch. Designed for right-angle through-hole mounting, this shrouded dual-row connector utilizes gold-plated contacts for reliable signal transmission. The housing is constructed from black polyester reinforced with glass fiber, rated UL94 V-0 for flammability. It operates within a temperature range of -55°C to +125°C and supports wire gauges from 28 AWG to 24 AWG.
Feature Summary
- Right-angle through-hole mounting design for space-efficient board integration
- Shrouded dual-row construction providing four-wall protection
- Gold-plated contact surfaces ensuring durable electrical connectivity
Applications
- Industrial control systems requiring robust interconnects
- Test and measurement equipment interfaces
- Automotive electronics modules
Procurement Notes
Verify the specific suffix 'L' indicates the right-angle orientation and '1' denotes the tin/lead plating variant on the column contacts. Confirm RoHS compliance status as some variants may differ. Ensure the ordering part number matches the exact position count and gender requirements for the target PCB layout.
Selection Notes
Select this component when a right-angle male header is required for tight vertical clearance constraints. The 2.00mm pitch allows for dense circuit layouts. Consider the mating height and stack-up requirements against corresponding female connectors in the same Datamate L-Tek series to ensure proper mechanical engagement.
Part Context
This part belongs to the Datamate L-Tek family, known for high-density interconnect solutions. The B5743 prefix specifically identifies male headers within this ecosystem. It complements female counterparts like the B5740 series, forming a complete mating pair for versatile electronic assembly needs.
Replacement Considerations
Direct substitutes include other Harwin Datamate L-Tek male headers with identical 18-position counts and right-angle through-hole termination. Verify that alternative parts maintain the same 2.00mm pitch and shrouded design to ensure mechanical compatibility.
