Safety button 1 NC nickel-plated ring ST22-B-01. ST22-B-01\.

Safety button – reliable control and protection

This safety button, designated ST22-B-01, is a control element designed for applications requiring operational certainty and minimizing the risk of accidental operations. Equipped with a single normally open contact, it is ideal for systems where precise and controlled starting or stopping of processes is essential. The construction with a red mushroom-shaped button and a gray front ring provides high visibility and easy identification in industrial conditions.

Solid construction and high resistance

The button is characterized by a solid construction, confirmed by the IP65 protection class. This means effective protection against dust and water jets, guaranteeing reliable operation even in harsh environmental conditions. The front ring made of high-quality plastic ensures durability and resistance to mechanical damage. A standard 22 mm mounting hole diameter simplifies integration with existing control panels and electrical cabinets.

Key features and applications

• Safety function: The non-latching button requires deliberate unlocking, preventing accidental starting or stopping of the device.
• Durability: Suitable for operation in a wide temperature range (from -40°C to +70°C) and resistant to vibrations and shocks.
• Versatility: Can be used in various industrial applications, such as automation, access control systems or specialized devices.
• Screw connection: Provides a secure and durable electrical connection of wires with a cross-section from 1 mm² to 2.5 mm².
• Compliance with standards: The product meets the requirements of PN-EN 60947-5-1 and IEC 60947-5-1 standards, guaranteeing safety of use.

The ST22-B-01 button is a reliable solution for installers and end-users looking for a control element with high functionality and durability. However, it should be remembered that this is not an element intended for emergency stop (E-STOP) function, but for specific applications requiring maintaining the state after activation and deliberate unlocking.
