Overview
The Harwin M80-7703445 is a 34-position receptacle connector from the Datamate M80 series, designed for board-to-board or cable interconnects. It features a 2 mm pitch and utilizes gold-plated phosphor bronze contacts rated for 3 A current. The housing is constructed from black polyamide (PA) with an operating temperature range of -55°C to +125°C. This component provides reliable electrical connections in compact applications requiring high-density power and signal transmission.
Feature Summary
- High-density 34-position configuration within a compact form factor
- Gold-plated phosphor bronze contacts ensure reliable conductivity
- Polyamide housing offers durability across extreme temperature ranges
Applications
- Compact electronic device interconnects
- Board-to-board power and signal transmission
- Cable harness connections in industrial equipment
Procurement Notes
Verify the specific mating counterpart requirements, as this is a receptacle unit. Confirm that the design accommodates the 2 mm pitch and 34-position layout. Ensure environmental conditions stay within the specified -55°C to +125°C range. Check for any specific handling instructions regarding the gold-plated contacts during assembly.
Selection Notes
Select this model when a high-pin-count, small-footprint solution is required. The 2 mm pitch allows for dense packing compared to larger connectors. Consider the 3 A rating per contact for power distribution needs. Verify compatibility with the corresponding male header or cable assembly from the same Datamate M80 family.
Part Context
This part belongs to the Datamate M80 series by Harwin, known for robust performance in demanding environments. The series supports various configurations including board-to-board and cable-to-board options. The M80-7703445 specifically addresses the need for higher pin counts in space-constrained designs while maintaining electrical integrity.
Replacement Considerations
No direct substitute part numbers are publicly confirmed for this specific variant. Cross-referencing requires matching the 34-position count, 2 mm pitch, and receptacle type within the Datamate ecosystem.
