The Omron SHL-W2155-01 is a compact and sealed enclosed switch designed for micro-load applications in industrial automation. It features a hinge roller lever actuator and a snap-action mechanism that ensures crisp switching response. With SPDT contacts, the switch supports non-inductive loads of 0.1 A at 125 VAC or up to 30 VDC, making it suitable for low-current signal control.
Its durable zinc housing is rated IP67, offering full protection against dust and water ingress. The switch provides a long service life—over 10 million mechanical operations and 500,000 electrical operations under rated conditions. It handles vibration (10–55 Hz) and shock (up to 1,000 m/s²), making it dependable even in high-motion systems.
The SHL-W2155-01 is widely used in safety devices, machine tool automation, and limit detection systems where compact size, repeatability, and environmental resistance are critical.
