Overview
The Omron ZC-Q2155 enclosed limit switch is a sealed electrical switch designed for industrial automation and machinery control. This general-purpose limit switch features a durable metal enclosure with a cross-roller plunger actuator and snap-on terminal cover. The ZC-Q2155 delivers consistent electrical switching with SPDT (Single Pole Double Throw) contact configuration rated for 10A at 250VAC, making it suitable for detecting machine position, controlling conveyor systems, and signaling equipment state changes.
Key Features
- IP67 sealed enclosure — protects internal contacts from dust, moisture, and environmental contamination
- Cross-roller plunger actuator — low operating force (11.8 N) with smooth, repeatable actuation
- SPDT contact configuration — enables flexible circuit control with one normally open and one normally closed contact
- 500,000 electrical operations rated — verified durability under loaded switching conditions
- Panel-mount screw terminals — straightforward installation in control enclosures and machine cabinets
- ZC series standardization — compatible with established industrial control systems and replacements
