Siemens 3SE29020AB20 Foot Switch With Protective Cover

Siemens 3SE29020AB20 is a momentary-contact foot switch with a single pedal from the SIRIUS 3SE29 family. It features a rugged metal enclosure rated IP65, 1 normally open (NO) and 1 normally closed (NC) contact, and a cable entry of M20 x 1.5. The AB20 variant is documented as without a protective cover. Designed for hands-free operation in industrial environments, it is suitable for use on presses and punches where the operator’s hands must stay clear of moving parts. As a momentary device, the pedal returns to its resting position after actuation, providing a brief signal when stepped on. The dual contacts enable simple control layouts such as start/stop or enable/disable functions within a control circuit, and the IP65-rated enclosure helps protect against dust and water jets from any direction in challenging workshop conditions. This foot switch integrates with Siemens’ SIRIUS control ecosystems and complements other 3SE29 safety-foot-switch components in the same family, delivering reliable, rapid actuation for safety-related tasks in automation.
