M80-8512045

Overview

The M80-8512045 is a Datamate L-Tek male header connector featuring 20 positions in a dual-row configuration. It utilizes a 2 mm pitch and is designed for right-angle through-hole mounting on printed circuit boards. The component supports board-to-board and wire-to-board interconnections with a voltage rating of 120 V and a current capacity of 3 A per contact. Contacts are manufactured from phosphor bronze with gold plating to ensure reliable signal transmission. The housing is constructed from PPS thermoplastic, providing stability across an operating temperature range of -55°C to +125°C.

Feature Summary

• High-reliability four-finger beryllium copper contacts ensure connection integrity under severe vibration and shock conditions.
• Robust design withstands high mating cycles without performance degradation in harsh environments.
• L-Tek series offers versatile connectivity options including both latched and unlatched configurations.

Applications

• Industrial control systems requiring secure connections under mechanical stress
• Automotive electronics exposed to high vibration and acceleration
• Aerospace instrumentation demanding long-term reliability

Procurement Notes

Verify the specific suffix codes against official Harwin documentation to confirm exact pin count, orientation, and locking mechanism variations. Ensure compatibility with mating receptacles within the same Datamate L-Tek family. Cross-reference terminal specifications to match application current requirements. Confirm RoHS compliance status through manufacturer datasheets prior to integration into regulated assemblies.

Selection Notes

Select this model for applications necessitating right-angle PCB entry with robust mechanical retention. The 20-position layout suits moderate-density signal routing where space efficiency is critical. Evaluate thermal management needs given the 125°C upper limit. Consider environmental sealing requirements if operating in moisture or dust-prone areas, as standard housings may require additional protection measures.

Part Context

This component belongs to the Datamate L-Tek series by Harwin, engineered for safety-critical and high-vibration environments. The series emphasizes durability through specialized contact geometry and high-grade materials. It serves industries such as automotive, aerospace, and industrial automation where connection failure is not an option. The M80 prefix denotes the specific product line within the broader connector portfolio.

Replacement Considerations

Direct substitutes include other Harwin M80-series headers with matching 20-position, right-angle, through-hole specifications. Verify identical 2 mm pitch and contact material composition when sourcing alternatives. Cross-model compatibility depends on precise alignment of housing dimensions and locking features.
