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.","metaTitle":"Siemens 3SF5814-2DE20 Emergency Stop, 22 mm, IP67","metaDescription":"Siemens 3SF5814-2DE20 emergency stop pushbutton with integrated LED. 26.5-31.5 V DC, IP67 rated.
