M80-8503445

Overview

The Harwin M80-8503445 is a Datamate L-Tek double in-line (DIL) vertical printed circuit board (PC) tail socket assembly. This connector system features a 2 mm pitch and comprises 34 positions arranged in two rows. The unit utilizes gold-plated phosphor bronze contacts housed within a black polyphenylene sulfide (PPS) shell, ensuring durability and reliable electrical performance. Designed for through-hole mounting, the component operates within a temperature range of -55°C to +125°C and supports a rated current of 3 A with a voltage rating of 120 V.

Feature Summary

• Features a four-finger beryllium copper contact structure for secure mating and high reliability under vibration.
• Constructed with a PPS housing material offering UL 94 V-0 flammability rating.
• Designed as a shrouded header to ensure correct alignment during board-to-board connection.

Applications

• Board-to-board interconnections in industrial control systems
• Data acquisition modules requiring robust signal integrity
• Automotive electronic control units (ECUs)
• Medical instrumentation internal wiring

Procurement Notes

Verify the specific pin count and housing configuration against the official Harwin datasheet before ordering. Confirm that the required contact plating thickness meets the application's cycle life requirements. Ensure the selected variant matches the intended PCB footprint and mounting orientation specifications.

Selection Notes

Select this component when a high-density, vertically mounted DIL socket is required for rigid board connections. Consider the 2 mm pitch constraint and the 3 A current capacity relative to the total number of active pins. Evaluate the need for latch mechanisms if additional retention force is necessary beyond standard friction fit.

Part Context

This part belongs to the Datamate L-Tek series by Harwin, designed for applications demanding high reliability in harsh environments. The series is characterized by its compact form factor and ability to withstand significant mechanical stress. It serves as a critical interface solution in sectors where connection failure is not an option.

Replacement Considerations

Direct substitutes include other Harwin Datamate L-Tek sockets with identical 2 mm pitch and 34-position configurations. Verify compatibility with existing mating headers regarding shell size and latch presence before substitution.

FAQ
