Safety button 3NC standard SP22-BN-03. SP22-BN-03\.

Safety button for industrial applications and control

This red safety button from the SP22 series is a reliable control element designed for applications requiring immediate stop or emergency shutdown of equipment. The mushroom-shaped design and red color ensure easy identification in crisis situations. Designed for mounting in 22 mm diameter holes, it offers a solid electrical connection using screw terminals.

Construction and functionality

The button is characterized by a non-latching design, which means that after pressing it remains in the active position until manually released. It has three normally open contacts, allowing effective circuit interruption in case of danger. The IP65 protection class guarantees resistance to dust and water jets, making it an ideal solution for harsh industrial conditions. Made of durable materials – plastic for the front ring – ensures long-lasting and reliable operation.

Application and compliance with standards

The SP22-BN-03 button is used in a wide range of devices and machines, such as:

• Industrial control systems
• Production lines
• Machines and equipment requiring emergency stop
• Operator panels
• Building automation

It meets the requirements of PN-EN 60947-5-1 and IEC 60947-1 standards, confirming its safety and compliance with European standards. Suitable for operation at temperatures from -40°C to +70°C, and also resistant to vibrations and mechanical shocks (according to IEC 60068-2-6 and IEC 60068-2-27), which ensures its reliability even in demanding operating conditions. Connection cables with a cross-section of 1…2.5 mm² (solid) or 0.75…1.5 mm² (stranded) provide a solid electrical connection.
