A79653-001

Headers, Receptacles, Female Sockets Overview

The Omnetics A79653-001 is a Polarized Nano Series connector header designed for surface mount, right-angle termination. It features 24 positions with a 0.025 inch (0.64 mm) mating pitch and single-row configuration. The contacts utilize gold plating with a thickness of 50.0 µin (1.27 µm) on copper alloy materials. Rated at 1A per contact, it operates within a temperature range of -55°C to 125°C. The housing is made of thermoplastic in a natural color, with an insulation height of 0.080 inches (2.03 mm).

Headers, Receptacles, Female Sockets Feature Summary

• Polarized design ensures correct mating alignment and prevents misconnection.
• Right-angle surface mount termination facilitates compact board layout integration.
• Gold-plated circular contacts provide reliable signal transmission in harsh environments.

Headers, Receptacles, Female Sockets Applications

• High-reliability aerospace interconnect systems
• Military electronic equipment connections
• UAV payload interface modules

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific series designation, as this part belongs to the Polarized Nano family distinct from standard Nano Strip variants. Confirm that the right-angle orientation matches the PCB footprint requirements. Ensure compatibility with mating female connectors from the same polarized series to maintain alignment integrity. Check for any updated environmental compliance documentation prior to final procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when space-constrained designs require right-angle connectivity with high reliability. The polarized feature is critical for applications where incorrect mating could cause damage. Consider the 1A current rating per contact against total system load requirements. Evaluate the thermal performance within the specified -55°C to 125°C range for the intended operating environment.

Headers, Receptacles, Female Sockets Part Context

This connector is part of Omnetics' Polarized Nano (PZN) series, engineered for precision interconnects in demanding sectors. It complements other PZN components like the A79623-001, offering specialized polarization for enhanced assembly accuracy. The series supports miniaturization goals while maintaining rugged performance standards required for defense and aerospace hardware.

Headers, Receptacles, Female Sockets Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include models from the same Polarized Nano series with matching pin counts and orientations. Verify mechanical dimensions and polarization keying before substitution to ensure functional interchangeability without redesigning the PCB footprint.
