Premium Amphenol Circular Connector Yh3116A16-26s for Reliable Connections

YH3116A16-26S Circular Connector, YH3116 Series

The YH3116A16-26S is a circular electrical connector designed for aerospace, avionics, and industrial platforms. It belongs to the YH3116 series connector family. Note: The YH3116 series is a distinct connector standard, separate from MIL-DTL-38999 / GJB599, MIL-DTL-27484 (MS27484), MIL-DTL-27497 (MS27497), MIL-DTL-27508 (MS27508), MIL-DTL-26482 (62GB), JY27466 (GJB), 8D series, Y50 series, YLH series, and ZH8525 series, and is not directly form-fit-function interchangeable with any of those connectors unless confirmed by the supplier.

This connector features shell size 16 (approximately equivalent to D38999 shell size E / 17), insert arrangement 26 (confirm exact contact count and type with supplier), and socket contacts (S). The "A" designator indicates a specific style or type code within the YH3116 series (confirm exact meaning with supplier). The design supports EMI shielding and removable crimp contacts.

Compatible Applications

The YH3116A16-26S connector is intended for platforms that require YH3116 series compliant interconnects in shell size 16, using socket contacts. Typical use cases include:

• Aircraft and helicopter wiring harness interconnects (YH3116 series standard)
• Avionics LRUs, radar, and communication equipment
• Ground vehicles and rugged electronic enclosures
• Shipboard and industrial equipment requiring circular connectors
• Programs that standardize on YH3116 series interfaces

Selection Guide

Installation Notes

• Verify shell size, insert arrangement, and contact gender before mating. Confirm the meaning of the "A" style code and exact contact layout for arrangement 26 with supplier.
• Use the correct crimp tooling for the contact size specified by arrangement 26 (confirm contact type with supplier).
• Fully engage the coupling mechanism with the mating YH3116 series connector until securely seated.
• Mate only with YH3116 series connectors of the same shell size, arrangement, and opposite contact gender (pin).
• Do NOT attempt to mate with D38999/J599 Series III, MS27484, MS27497, MS27508, 62GB/MIL-DTL-26482, JY27466, 8D, Y50, YLH, or ZH8525 series connectors — YH3116 series is a different standard and is not interchangeable unless confirmed by supplier.
