ZH23 Series 4 Pin Bayonet Electrical Receptacle

Product Information

The ZH23 series 4 pin receptacle is a circular electrical connector designed for low-frequency AC and DC circuits. It combines a four-contact interface with five-button positioning and bayonet locking, providing a defined mating direction and a convenient connection method for compatible plugs.

The five-button structure provides mechanical guidance during mating, while the anti-insertion design helps prevent incorrect orientation. After the plug reaches the correct position, the bayonet mechanism is engaged through rotation to secure the connection. This operating method is suitable for equipment interfaces where convenient connection and repeated maintenance are required.

The electrical interface uses gold-plated copper alloy contacts with PPS insulation. The shell can be manufactured from anodized aluminum alloy or industrial-grade nickel-plated zinc alloy. With a specified operating temperature range of -60°C to +200°C, 96-hour salt spray resistance and defined vibration and impact performance, the connector is suitable for equipment operating under demanding environmental conditions.

The ZH23 series is designed to match and interchange with corresponding СНЦ23 series connectors, subject to confirmation of dimensions, contact arrangement and electrical specifications.

Characteristics

• -- 4-pin male-contact receptacle

• -- Five-button positioning for guided mating

• -- Anti-insertion structure for controlled connector orientation

• -- Bayonet coupling for quick connection and release

• -- Gold-plated copper alloy contacts

• -- PPS insulating material

• -- Aluminum alloy or zinc alloy shell options

• -- Operating temperature: -60°C to +200°C

• -- Mechanical and working life: 500 cycles

Operating Principle

The receptacle works with a compatible ZH23 bayonet plug. The positioning keys first guide the plug into the correct orientation. Rotating the plug then engages the bayonet locking structure and secures the connection.

Four gold-plated copper alloy contacts provide the electrical paths, while PPS insulation separates the contact positions. The treated metal shell provides mechanical support and contributes to the specified environmental performance.

Applications

Suitable for low-frequency AC/DC connection in industrial control equipment, automation systems, instrumentation, electrical devices, testing equipment and other applications requiring a compact circular connector with quick coupling.
