The TFH 232-22UEDR is a robust and reliable foot switch with an integrated emergency stop function, designed for industrial applications. The housing is made of powder-coated aluminum, providing high resistance to mechanical stress. The pedal area is made of glass-fiber reinforced plastic, while the protective cover is also made of aluminum, ensuring effective protection against environmental and mechanical impacts.

The foot switch can be used in both momentary and latching modes, offering flexible operation. It features two normally closed (NC) contacts and two normally open (NO) contacts, operating on a slow-action switching principle for precise control. The switch is certified according to EN ISO 13849-1 safety standards and is designed for a maximum service life of 20 years.

With an IP65 protection rating, the foot switch is dustproof and resistant to water jets, making it suitable for harsh industrial environments. The electrical connection is made via a screw terminal M20 x 1.5, ensuring a secure connection.

The TFH 232-22UEDR offers a high mechanical lifespan of 1 million switching cycles and a maximum switching frequency of 3,600 operations per hour.
