CW Touchless Switch

Description

The low-profile CW touchless switches are suitable for many hygienic industrial and public automation applications. They are designed with a sleek and nearly flush (just 2 mm rise) low-profile surface silhouette. They are built for an industry standard 22 mm mounting hole and require only a shallow space behind the panel face, plus room for the wiring connector. The typical installation pitch is 1.2 in. (30 mm) width and 2 in. (50 mm) height. Operating temperatures range from -13 to +131°F (-25 to +55°C).

 

A rubber washer and locking ring ensure IP65/67 and NEMA Type 4X ratings are maintained. The CW1H housing and bezel is black plastic resin, and the CW4H is silver aluminum alloy metal. Although the switches are rated for outdoor use, are made from weather resistant materials, and are highly resistant to visible light, excessive exposure to ultraviolet rays from direct sunlight can cause material degradation, color fading, and even false signals. Additionally, as with almost any signaling device, dirt and water droplets can impact operation. Therefore, designers should check product performance before use and consider degrees of physical protection.

 

The switch front face contains a central emitter and receiver sensing lens and an LED indicator ring. Infrared LED diffuse reflection technology is used to detect objects. The detection distance is adjustable, typically ranging from 2.8 to 10.6 in. (70 to 270 mm) depending on the color, material, and surface condition of the object to be detected.
