M80-8542642

Overview

The M80-8542642 is a Datamate L-Tek header connector manufactured by Harwin Inc. It features a vertical, double in-line (DIL) configuration with 26 positions arranged in two rows of 13. The connector utilizes male pin contacts made from phosphor bronze, finished with tin and lead plating. Designed for board-to-board or wire-to-board applications, it employs a through-hole solder termination method. The housing is constructed from black thermoplastic material, providing UL94 V-0 flammability rating. Rated for 120V and 3A, the unit maintains a 2mm pitch between contacts.

Feature Summary

• Vertical DIL male pin configuration for reliable board-to-board or wire-to-board interconnection
• Friction latch mechanism ensures secure mating without additional locking hardware
• Tin/lead contact plating provides corrosion resistance and stable electrical conductivity
• Thermoplastic housing offers structural integrity and UL94 V-0 flame retardancy

Applications

• Industrial control systems requiring robust vertical interconnects
• Consumer electronics utilizing board-to-board signal transmission
• Automotive modules needing vibration-resistant friction-latch connections
• Test and measurement equipment interfaces

Procurement Notes

Verify the specific plating finish and latch type against project requirements, as variations exist within the Datamate L-Tek series. Confirm that the vertical orientation and 26-position count align with PCB footprint constraints. Ensure compatibility with mating sockets featuring corresponding friction latches. Check for RoHS compliance status if restricted substances are prohibited in the assembly process. Validate thermal performance ratings against operational environment limits.

Selection Notes

Select this component when a vertical, unlatched or friction-latched header is required for high-density 2-row layouts. The 2mm pitch suits applications needing moderate spacing between signals. Consider the tin/lead finish for cost-sensitive designs where long-term corrosion resistance is less critical than gold. Evaluate mechanical stability needs, as friction latches differ from positive locking mechanisms. Ensure the 3A current rating meets circuit load demands without excessive heating.

Part Context

This part belongs to the Datamate L-Tek family, designed for harsh environments involving shock, vibration, and acceleration. The series emphasizes durability through high-reliability contact designs capable of withstanding repeated mating cycles. L-Tek variants typically feature friction latches for quick assembly. The M80-8542642 specifically addresses needs for vertical mounting with standard through-hole soldering, fitting into broader industrial and commercial electronic assemblies.

Replacement Considerations

M80-8412642 is a confirmed substitute offering similar 26-position DIL male characteristics with tin/lead plating.

FAQ

Does the M80-8542642 include a positive locking mechanism?

No, it uses a friction latch system which secures the connection through tension rather than a rigid lock.

What is the contact material used in this connector?

The contacts are made from phosphor bronze, plated with tin and lead to ensure conductivity and durability.
