Product Specification

ZH23 Series 4 Pin Bayonet Circular Receptacle

Product Information

The ZH23 series 4 pin receptacle is an equipment-side circular connector developed for low-frequency AC and DC electrical circuits. Its combination of a guided five-button positioning structure and bayonet coupling provides a defined mating sequence, helping make connector installation more straightforward and reducing the possibility of incorrect insertion.

Unlike a threaded interface, the bayonet mechanism uses rotational engagement to secure the mating connector. This design is particularly convenient where connectors need to be connected, disconnected or serviced repeatedly. The receptacle incorporates four male contacts with gold-plated copper alloy construction and PPS insulation.

The ZH23 series is also designed for demanding environmental conditions. The specified operating range extends from -60°C to +200°C, while the connector provides 96 hours of salt spray resistance together with defined vibration, impact and humidity specifications.

Corresponding ZH23 products can be matched and interchanged with the Russian СНЦ23 series after checking dimensions, contact arrangement and electrical specifications.

Main Characteristics

• -- 4-pin male-contact receptacle for equipment-side integration

• -- Five-button positioning provides a defined mating orientation

• -- Anti-insertion structure helps reduce incorrect connection

• -- Bayonet coupling supports rapid mating and release

• -- Gold-plated copper alloy contacts

• -- PPS insulation material

• -- Aluminum alloy or industrial-grade zinc alloy shell construction

• -- Wide operating temperature range of -60°C to +200°C

• -- 500-cycle mechanical and working life

Connection Theory

The receptacle works together with a compatible ZH23 bayonet plug. The five-button positioning structure first guides the plug into the correct orientation. Once aligned, rotational movement engages the bayonet locking structure and secures the connection.

During operation, the four conductive contacts provide the electrical connection while PPS material separates the contact positions. Gold plating on the copper alloy contacts helps maintain the specified contact interface performance.

Applications

The receptacle can be integrated into industrial control equipment, automation systems, instrumentation, electrical devices, testing equipment and other low-frequency AC/DC systems requiring a compact circular interface with quick coupling.
