CHT1 Series Capacitive Push Buttons

The CHT1 Series Capacitive Push Buttons are designed for demanding applications where durability, reliability and vandal resistance are essential. Manufactured from stainless steel and available in multiple housing designs, the CHT1 series is suitable for machine control systems, access control applications and public infrastructure.

The capacitive touch technology enables operation without mechanical pressure, ensuring high user comfort and minimal wear. Optical feedback is provided through two LED rings, while the fully sealed sensor design protects against water, oil and harsh environmental conditions.

The sensor is completely encapsulated in cast resin, providing IP69K protection and exceptional resistance to shocks, impacts and vandalism. Depending on the model, hygienic versions compliant with DIN EN 1672-1/2 are available for food processing, healthcare and medical technology environments.

With multiple housing variants, mounting options and dimensions, the CHT1 series can be adapted to a wide range of industrial and hygienic applications.
