• IP69K (ingress protection) rating indicates the unit is completely sealed against dust, water jets and submersion in water
• Compact (75mm) installation width so you can mount it easily in confined spaces
• Latching actuation keeps the button in place until it's manually released, for added safety

NC (normally closed) refers to the contact position. Closed contacts supply uninterrupted power to an application. When you push this emergency push button from Siemens, it opens the contacts to interrupt the power supply and stop the machinery.
