About Safety switches with separate actuator (Without Locking)
Safety limit switches with separate actuator
The safety limit switches with separated actuator represent the most simple and economical solution in order to ensure the monitoring of safety gates, according to the standards in force. Available in different sizes and body material (thermoplastic or metal casing) and configurable with several contact versions.
Reliable Machine Guard ProtectionDesigned for the highest safety standards, this switch provides reliable and secure disengagement when machine guards are not in place. The device's positive opening contacts guarantee safety even in case of welded contacts, while the rugged housing and IP67 rating ensure performance in tough industrial settings.
Versatile Installation OptionsAccommodating top, side, or front actuator entry and multiple cable entry ports (2 x M16), the switch is simple to install within various machine layouts. Its compact dimensions (88 x 40 x 38 mm) and screw mounting offer flexible placement, making it ideal for both new installations and retrofits.
Durability and Long LifeManufactured with high-strength thermoplastic and built to withstand shock (30G, 11 ms), vibration (10-55 Hz/1 mm), and wide temperature ranges (-25C to +80C), the switch ensures lasting operation. The mechanical life of over one million cycles highlights its suitability for continuous industrial use.
FAQ's of Safety switches with separate actuator (Without Locking):
Q: How is the safety switch with separate actuator connected to a machine?
A: The switch utilizes screw terminals (M3.5) for easy and secure electrical connections. It features multiple actuator entry points (top, side, front), allowing flexible mounting options to suit different machine guard designs.
Q: What process ensures safety in this switch type?
A: The safety switch uses a positive opening NC contact system as specified in IEC 60947-5-1, ensuring that the circuit breaks mechanically when the actuator is removed, providing reliable disconnection in safety-critical applications.
Q: When should this safety switch be used?
A: The switch is intended for machine guard monitoring and access protection in industrial settings, especially when preventing unintended machine startup during maintenance or guard removal is essential.
Q: Where can the switch be installed on industrial equipment?
A: The compact, durable design with multiple actuator entry directions and dual M16 cable entry ports allows the switch to be placed on various machine types and guard locations, providing versatile installation options.
Q: What are the benefits of the separate actuator design?
A: The separate actuator enables flexible fitting to moving guards, while the non-lockable design simplifies installation and operation. It enhances safety by ensuring machines will only operate when the guard is closed and the actuator properly inserted.
Q: How does the switch withstand harsh operating environments?
A: Constructed with high-strength thermoplastic housing and rated at IP67 for dust and water resistance, the switch is suitable for challenging environments. It withstands vibration (10-55 Hz), shock (30G), and operates across a wide temperature range (-25C to +80C).
