Product details

The Siemens 3SF5814-2DE20 is a 22 mm panel-mount emergency stop pushbutton with an integrated LED, housed in an IP67-rated AS-Interface enclosure. It carries both EMERGENCY-STOP and EMERGENCY-OFF functions, with a pull-to-unlatch release mechanism. The operating voltage range is 26.5 to 31.5 V DC, and the unit is pre-wired on a strip terminal for quick panel integration.

IP67 and washdown deployment

Rated IP67, the enclosure withstands temporary immersion and high-pressure washdown — suitable for food-and-bev lines, washdown zones, or outdoor installations where moisture ingress is a concern.
