Schneider Electric ZB5AS844 Emergency Stop Push Button, 40 mm Mushroom Head, Red, Plastic, IP69K

The Schneider Electric ZB5AS844 is a robust emergency stop push button from the Harmony XB5 series, designed for industrial safety applications. Featuring a 40 mm red mushroom head actuator with turn-to-release mechanism, this plastic-bodied button offers high ingress protection up to IP69K, making it suitable for harsh environments including high-pressure washdown. The latching operation ensures reliable emergency stop functionality, and the unmarked head allows for custom labeling. This component requires a ZB5AZ009 fixing collar and ZBE10x contact blocks (sold separately) for full assembly.
