The Omron Z-15GQ22-B7 is a basic limit switch with a roller plunger actuator, designed for position detection in industrial machinery and conveyor systems. It uses snap-action contacts rated for 15 A at 250 VAC and 14 VDC, with a normally open and normally closed output configuration.
The 15 A current rating at 250 VAC covers most motor control and interlock circuits in material handling lines. The 14 VDC rating is notably lower — this switch is not intended for higher-voltage DC loads like 24 VDC solenoids without derating or a suppression diode. The 3.43 N operating force means the roller plunger requires a firm mechanical strike to actuate, typical for cam-operated or slide-gate positions where false triggering from vibration is a concern.
The roller plunger actuator makes this switch suitable for linear motion detection along a conveyor path — think end-of-travel stops, divert gate positions, or package presence at a merge point. The snap-action contacts give clean break and make, avoiding the arcing that can weld slow-acting contacts in high-cycle applications.
