A79654-001

Headers, Receptacles, Female Sockets Overview

The A79654-001 is a Polarized Nano series connector header manufactured by Omnetics. It features 24 positions arranged in a single row with a 0.025-inch (0.64mm) mating pitch and a 0.040-inch (1.02mm) row spacing. Designed for through-hole straight termination, the component utilizes gold-plated contacts with a 50.0µin thickness to ensure reliable signal transmission. The housing is constructed from thermoplastic material in a natural color, providing an insulation height of 0.170 inches. Rated for 1A per contact, it operates within a temperature range of -55°C to 125°C.

Headers, Receptacles, Female Sockets Applications

• High-reliability aerospace electronic systems
• Defense communication equipment interconnects
• Precision instrumentation board-to-board connections

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific order matches the Polarized Nano series designation and single-row configuration. Confirm the through-hole straight termination style aligns with the target PCB layout requirements. Ensure compatibility with mating components designed for the 0.025-inch pitch standard. Check for any specific handling instructions regarding the gold plating integrity during assembly processes.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when space-constrained designs require high-density interconnects with secure polarization. The single-row format simplifies routing compared to dual-row alternatives while maintaining robust electrical performance. Consider the through-hole mounting method for applications requiring higher mechanical stability than surface-mount options provide. Evaluate the thermal rating against the operational environment constraints.

Headers, Receptacles, Female Sockets Part Context

This part belongs to Omnetics' Polarized Nano family, which emphasizes precision and reliability in miniature form factors. The series is engineered for harsh environments where standard connectors may fail due to vibration or misalignment. As a male header, it serves as the stationary interface in board-to-board or cable-to-board assemblies within the broader Nano Strip ecosystem.
