Safety button 2 NC 1 NO standard SP22-BN-21. SP22-BN-21\.

Safety button – reliable emergency stop

This red safety button, with a diameter of 22 mm, is a key element in machine and device control systems requiring immediate shutdown. Designed for mounting in 22x22 mm openings, it provides a quick and reliable response in emergency situations. The mushroom-head design and clear red color make it easily recognizable and accessible when needed.

Construction and application

The SP22-BN-21 button is a complete element, ready for connection thanks to the screw connection. It has two normally closed and one normally open contact, allowing its versatile use in safety circuits. The IP65 protection class guarantees resistance to dust and water jets, making it an ideal solution for both production environments and more demanding working conditions. Made of durable materials – plastic for the front ring – ensures long-term reliability.

This button is used in:

• Industrial machines and equipment
• Control panels
• Automation systems
• Applications requiring safe emergency shutdown
• Workstation equipment where operator safety is a priority

Characteristics and benefits

• Safety first: Mushroom-head design and non-latching function (with release by pulling) ensure a reliable and secure emergency stop.
• Durability and resistance: IP65 protection class protects against external factors such as dust and moisture, which translates into a long device life.
• Versatility: Can be used in various circuits thanks to the contact configuration (2NC, 1NO).
• Easy installation: Screw connection facilitates quick and efficient connection to the electrical installation.
• Compliance with standards: The product meets the requirements of PN-EN 60947-5-1 and IEC 60947-5-1/5/5 standards, which guarantees its safety and reliability.
• Solid construction: Made of high-quality materials, ensuring durability even in harsh industrial conditions.
• Clear identification: The red color of the button and the round shape of the lens facilitate quick identification in emergency situations.

Additional information regarding electrical parameters (rated continuous current 10A, rated switching current AC-15 2.5A) allows for the selection of appropriate electrical installation protection. Vibration and shock resistance (according to IEC 60068-2-6 and IEC 60068-2-27) confirms its suitability in demanding industrial environments.
