Complete drive safety ring black ST22-B\CZ

Safety button drive ST22-B\CZ – reliable control and protection

This safety button drive, catalog number ST22-B\CZ, is a control element designed for applications requiring reliable operation and minimizing the risk of accidental activation. It is a key component in systems where precision and safety are a priority. Manufactured by the renowned SPAMEL, it combines a solid construction with a functional design.

Construction and application

The ST22-B\CZ drive features a twist-release mechanism. This means that changing the button state requires intentional rotation, effectively preventing accidental switching on or off. This solution is particularly useful in industrial applications where unwanted machine start-up can lead to downtime or hazards. The red button color and gray front ring made of plastic provide good visibility and easy identification in production conditions. The standard mounting hole diameter of 22 mm allows for easy integration with existing control panels.

Advantages and characteristic features

• Safety: Twist-release mechanism minimizes the risk of accidental activation.
• Durability: Made of high-quality materials guarantees long life even in harsh industrial conditions.
• Resistance to external factors: IP65 protection rating provides resistance to dust and strong water jets, allowing the drive to be used in demanding environments.
• Standard dimensions: 22 mm hole diameter facilitates mounting and replacement.
• Clear identification: Red button color and gray front ring provide good visibility.
• Non-self-returning: Maintains state after activation – ideal for applications requiring a constant safety signal.
• Front ring material: Made of durable plastic, resistant to mechanical damage.

It is important to remember that this drive is not intended for emergency stop (E-STOP) function, and its application focuses on other safety scenarios requiring intentional unlocking and maintaining the state after activation. It is an ideal choice for machines and equipment where the safety signal must be maintained until operator intervention, e.g. in systems protecting against uncontrolled movement or start-up.
