Safety button 2NC black ring ST22-B-02\CZ

Safety button for control panels

This two-position safety button, designated ST22-B-02\CZ, is a reliable control element designed for mounting in 22 mm diameter holes. Made of high-quality plastic, it features a solid construction and a high degree of protection IP65 – guaranteeing its resistance to dust and water jets. It is ideal for use in demanding industrial conditions and in equipment exposed to moisture.

Construction and application

This button is designed with operator safety and reliable operation in mind. A round lens and black front ring provide clear visual identification. Thanks to its two control positions, the button allows for the implementation of various functions depending on the application needs – from simple on and off switching to more complex control operations. It finds application in control cabinets, machines and industrial equipment where high reliability and safety are required.

Key features and benefits

• Mechanical durability: The button withstands up to 300,000 switching cycles, which translates to a long service life and minimizes the need for replacement.
• Environmental resistance: A wide operating temperature range (-40°C to +70°C) and high resistance to vibration and shock make the button perform perfectly in harsh industrial conditions.
• Safety: IP65 protection protects against dust and water ingress, ensuring safe operation even in humid environments.
• Compliance with standards: The product meets the requirements of PN-EN 60947-5-1, IEC 60947-5-1 and IEC 60947-1 standards, confirming its high quality and safety of use.
• Adapted to different types of wires: The possibility of connecting solid wires with a cross-section of 1…2.5 mm² and stranded wires with a cross-section of 0.75…1.5 mm² provides installation flexibility.
• Electrical parameters: Suitable for operation with rated currents up to 10A (continuous) and switching currents depending on the load category (AC-15/DC-13). Short-circuit protection of the switching element is 10A (fast fuse insert) or 1kA (expected short-circuit current).
