ZH23 Series 4 Pin Bayonet Plug with Male Contacts

Product Information

The ZH23 series 4 pin bayonet plug is a straight circular connector designed for low-frequency AC and DC circuit connections. Its cable-side plug configuration combines four male contacts with a guided positioning structure, providing a practical interface for equipment and cable assemblies that require quick and repeatable connection.

The five-button positioning system helps establish the correct orientation before mating, while the anti-insertion structure helps reduce incorrect engagement. Once aligned, the bayonet coupling mechanism secures the connector through rotational locking, allowing faster connection and release than conventional threaded coupling.

The connector uses gold-plated copper alloy contacts and PPS insulation. Its metal shell is available in aluminum alloy with anodized treatment or industrial-grade zinc alloy with nickel plating. The specified operating temperature of -60°C to +200°C, together with 96-hour salt spray resistance and defined vibration and impact performance, makes the connector suitable for equipment exposed to demanding environmental conditions.

The ZH23 series can be matched and interchanged with corresponding СНЦ23 series connectors after dimensional, mechanical and electrical verification.

Connection Technology

The plug uses a keyed bayonet coupling system. Before mating, the five-button positioning structure guides the plug toward the corresponding orientation. After the contacts are aligned, the plug is rotated to engage the bayonet locking structure.

The four gold-plated copper alloy contacts establish the electrical connection, while the PPS insulation separates individual contact positions. The treated metal shell provides mechanical protection and supports the connector's specified environmental performance.

Applications

The ZH23 4 pin plug is suitable for cable assemblies and equipment connections in industrial control systems, automation equipment, instrumentation, electrical devices, testing equipment and low-frequency AC/DC circuits where quick coupling and environmental resistance are required.
