M80-8501645

Overview

The Harwin M80-8501645 is a 16-position, two-row board-to-board receptacle from the Datamate L-Tek series. It features a 2 mm pitch and utilizes gold-plated beryllium copper contacts for reliable signal transmission. Designed for through-hole straight installation, this connector supports a maximum voltage of 120 V and a current rating of 12 A. The housing is constructed from nylon with a UL94 V-0 flammability rating. It operates within a temperature range of -55°C to +125°C and employs a locking ramp fastening mechanism to ensure secure mating in high-vibration environments.

Feature Summary

• High-reliability four-finger beryllium copper contacts ensure connection integrity under shock and vibration
• Locking ramp fastening system provides secure mechanical retention during mating cycles
• Nylon housing offers thermal stability and meets UL94 V-0 flammability standards

Applications

• Industrial control systems requiring robust board-to-board interconnects
• Automotive electronics exposed to high vibration and shock loads
• Medical devices demanding high reliability and repeated mating durability

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm contact plating thickness and housing color variants. Ensure the selected part number matches the required pin count and row configuration for your PCB layout. Cross-reference the locking mechanism type with mating header specifications to guarantee compatibility. Confirm that the through-hole termination style aligns with your assembly process capabilities.

Selection Notes

Select this component when high mechanical retention is critical due to environmental stressors like vibration or acceleration. The 12 A current rating suits moderate power applications, while the 120 V rating defines its electrical isolation limits. Consider the 2 mm pitch for density requirements and verify that the straight orientation fits the available vertical clearance on the target assembly.

Part Context

This receptacle belongs to the Datamate L-Tek family, known for high-cycle durability and safety-critical performance. The M80 series design emphasizes resistance to harsh conditions, making it suitable for sectors where failure is not an option. Its standardized dimensions facilitate integration into modular electronic architectures requiring dependable physical connections.

Replacement Considerations

Direct substitutes must match the 16-pin, 2-row, 2 mm pitch specification and locking ramp interface. Verify that alternative connectors maintain identical current and voltage ratings alongside compatible operating temperatures. Ensure the replacement part uses similar contact materials and housing flammability ratings to preserve system safety compliance.
