This range of Head Emergency Buttons are used in control cabinets, control panels, in elevator construction, on conveyor or transport plants. After the manual actuation, the components initiate or switch off work processes and functional processes. The range of NDR Series Emergency Stop Push Buttons are available in the form of pushbuttons, joystick switches or key-operated switches. They are available in a single, dual and tri state contact blocks. There is an option to have N/O (normally open) and N/C (normally closed) contact versions to satisfy every requirement.

Schmersal Contact Block for NDR E-Stop, NO Contact, 400V - EF03.2
This contact block from Schmersal is used to make or break electrical connections. It quickly cuts off power to industrial equipment in the event of an accident. It has silver contacts that are highly conductive for a reliable electrical connection. The unit is made of a glass-reinforced thermoplastic material that's durable and impact-resistant for long-lasting use in demanding environments. As this material is flame-resistant and self-extinguishing, it won't promote the spread of flames in the event of a fire.
Features & Benefits
• Robust mechanical life of 10,000,000 operations for long-lasting performance • Wide operating temperature range of -25°C to +80°C for use in harsh environments • IP40 (ingress protection) rating indicates that it's protected against solid objects larger than 1mm in size • Compact dimensions of 46 (length) x 10 (width) x 60mm (depth) for use in areas where space is limited • Light weight of 20g to reduce strain on equipment
Applications
• Construction machinery • Process and packaging equipment • Conveyors
What is a normally open contact?
A normally open (NO) contact is one that's in a non-conductive state when the switch is de-energised. This means it doesn't allow current flow until it's switched on.
