Siemens Emergency Stop Push Button, M20 Connectors, 85 (H) x 85 (W) x 112.5mm (D) - SIRIUS ACT Series - 3SU1801-0NA00-2AC2
Improve workplace safety with this emergency stop push button from Siemens. Its durable polyamide construction is resistant to oils and detergents and has been extreme-element tested to guarantee a long service life in demanding environments. An IP67 (ingress protection) rating means the device can withstand immersion in up to 1m of water for 30 minutes, while an IP69K rating indicates it can endure rough treatment and high-temperature cleaning. This makes it suitable for use in industries including food and beverage production and pharmaceuticals.
• Functions on AC and DC circuits, allowing for versatility in application
• Bright yellow casing and red push button make the unit clearly visible and easy to find in an emergency situation
• Snap-on design allows for straightforward one-handed installation
• Wide operating temperature range between -25°C to +70°C for use in demanding environments
What's the difference between an emergency and a general-purpose push button?
You can use an emergency push button to shut down machinery or equipment when a dangerous situation occurs in the workplace. It is used less frequently than a general-purpose one, which you can use daily to start or stop a machine.
