B5743-212-M-L-3

Overview

The Harwin B5743-212-M-L-3 is a Datamate L-Tek male plug connector featuring a double-row, right-angle configuration with 12 positions. It utilizes a 2 mm pitch and employs through-hole termination for board mounting. The contacts are gold-plated copper alloy pins designed for reliable signal transmission. The housing is constructed from high-temperature polyester reinforced with glass fiber, rated UL 94 V-0. This component operates within a temperature range of -55°C to +125°C and supports mating with compatible female receptacles in the same series.

Feature Summary

• Right-angle horizontal orientation facilitates compact board layout integration.
• Gold-plated contact surfaces ensure durable electrical connectivity.
• High-temperature resistant housing material provides structural stability.

Applications

• Industrial control systems requiring robust interconnects
• Test and measurement equipment interfaces
• Automotive electronics modules

Procurement Notes

Verify the specific suffix codes against official Harwin documentation to confirm pin count, row configuration, and termination style. Ensure compatibility with mating connectors regarding latching mechanisms and PCB stack-up requirements. Cross-reference part numbers with current manufacturer listings to confirm availability status and any recent product change notifications.

Selection Notes

Select this model when a right-angle male connection is required for space-constrained designs. The double-row arrangement allows for higher density compared to single-row alternatives. Confirm that the through-hole mounting method aligns with the target PCB manufacturing capabilities and that the operating temperature range meets environmental specifications.

Part Context

This component belongs to the Datamate L-Tek family, known for its secure locking mechanisms and high reliability. The B5743 prefix typically denotes male plugs within this series. The L-3 suffix indicates specific physical characteristics such as the right-angle form factor and termination type, distinguishing it from vertical or straight variants.

Replacement Considerations

Compatible substitutes include other Harwin Datamate L-Tek male plugs with matching 2 mm pitch and 12-position count. Verify mechanical dimensions and latching interface compatibility before substitution. Alternative manufacturers may offer similar connectors but require validation of electrical ratings and physical fit.
