ZH127 Series 4 Pin Bayonet Socket – Straight Panel Mount Connector

Product Description

The ZH127 Series 4 Pin Bayonet Socket is designed for reliable electrical connection and signal transmission in industrial and professional electronic equipment. Based on proven circular connector technology, the ZH127 Series provides stable performance in both AC and DC circuits, supporting frequencies up to 3 MHz and voltage ratings up to 700 V (amplitude). Its compact structure, multi-level key positioning design, and secure bayonet coupling system provide convenient installation while ensuring accurate alignment and dependable operation.

This panel-mount socket features a straight orientation and solder termination method, making it suitable for equipment requiring stable fixed installation and reliable internal wiring. The aluminum alloy shell provides mechanical protection and durability, while the Bakelite insulating material ensures excellent electrical isolation between contacts. Gold- or silver-plated contacts help reduce contact resistance and maintain consistent conductivity during repeated connection cycles.

The ZH127 Series adopts a practical bayonet locking mechanism that enables quick connection and disconnection while maintaining strong mechanical retention. With excellent vibration resistance, wide operating temperature capability, and a long mechanical life of 500 mating cycles, this connector is suitable for various low-frequency electronic systems and electrical equipment. It is fully interchangeable and intermateable with compatible OHS-BC, ONTs-BS, SNTs127, and SNC127 connector series, providing a convenient replacement and integration solution.

Key Features

-- Reliable bayonet locking system for quick connection and secure installation

-- Compact 4-pin configuration for signal and power transmission

-- Gold/silver-plated contacts for stable electrical performance

-- Aluminum alloy shell for mechanical strength and durability

-- Bakelite insulation with excellent electrical isolation

-- Multi-level key positioning prevents incorrect mating

Working Principle

The socket creates an electrical connection through precisely positioned male contacts that align with the corresponding plug contacts. During mating, the bayonet coupling mechanism locks the connector securely with a simple rotation, maintaining stable contact pressure and preventing accidental separation. The insulated contact arrangement reduces electrical interference and ensures reliable signal transmission during continuous operation.
