Product Description

​The Omron ZC-W255 is a miniature enclosed limit switch featuring a short hinge roller lever actuator and a single-pole double-throw (SPDT) contact configuration. Designed for precise and reliable operation, it offers an electrical durability of 500,000 cycles and a mechanical durability of 10 million cycles, making it suitable for applications requiring frequent actuation. The switch is rated for a maximum current of 10 A at 125 VAC and 6 A at 30 VDC, providing versatility for various load types. It operates effectively in temperatures ranging from –10°C to 80°C, with an IP67 rating ensuring protection against dust and water ingress. Additionally, the ZC-W255 requires less operating force compared to conventional limit switches, enhancing precision in applications where accurate positioning is essential.
