Omron Z-15GQ21-B Limit Switch – 15A SPDT Cross-Roller Plunger, Panel Mount

Description

Product Overview
The Omron Z-15GQ21-B general-purpose basic switch detects mechanical movement and changes the state of an electrical circuit through a snap-action mechanism. Its panel-mount cross-roller plunger is designed for applications where a moving part presses against the actuator.
The switch features an SPDT contact arrangement, an M12 × 1 threaded mounting section, and M4 screw terminals. It can support compatible industrial equipment, machinery, and control mechanisms when its electrical and mechanical specifications match the application.

Key Features
– Cross-roller plunger: Provides a rolling contact surface for mechanical actuation.
– SPDT contacts: Offers common, normally open, and normally closed circuit connections.
– Panel-mount construction: Threaded mounting supports installation in compatible equipment.
– Screw terminals: Allow electrical connections using suitable wiring and terminal preparation.
– Snap-action operation: Supports repeatable switching when the actuator reaches its operating point.
– Defined operating characteristics: Omron specifies operating force, pre-travel, over-travel, and release force for this model.
Applications
Depending on the design and electrical requirements of the equipment, the Omron Z-15GQ21-B may be used for:
– Industrial machinery position detection
– Mechanical movement and travel-limit sensing
– Equipment control mechanisms
– Machine-tool control circuits
– Appliance and electromechanical assemblies
– Replacement of a compatible Omron Z-series basic switch
Installation and Compatibility
Before replacing an existing switch, compare the model number, mounting thread, roller dimensions, terminal layout, contact configuration, and electrical ratings. The IP00 rating means this switch does not provide an ingress-protection enclosure rating, so it should be installed in an appropriately protected environment.
Isolate power before wiring, and have a qualified technician verify the circuit and load requirements.
