Machine Safety Devices & Controllers
Balluff safety switches and safety sensors are designed for a variety of applications to protect both workers and machines. These safe switches and sensors offer various operating principles:
- Inductive for non-contact safe detection of position and end-of-travel of metallic objects
- Electromechanical and magnetic/REED or RFID-based for access
- Position verification for protection of personnel and machines
- Safety sensors and switches for a wide variety of applications
- Rugged housing versions with LED indicator
- Suitable for safety applications up to PLe/SIL3
- Savings of time and money plus prevention of errors due to standardized M12 connection technology
- Reduced installation expense and space requirements
- Suitable for heavy protective equipment
- Tamper resistant
- Insensitive to vibration and imprecise door alignment
Universal-use standard M12 cables save time and money during installation and assembly. They also help avoid wiring errors, gain clarity and ensure reliable monitoring.
Electromechanical Safety Switches
Interlock switch devices with a separate actuator simultaneously provide personnel and machine protection. When used with a machine controller and an isolating protection device, they secure the hazardous area against access.
- Sturdy metal housing with status display
- Rotatable actuator head with two insertion openings
- Plug-in M12 connection
Inductive Safety Sensors
Inductive safety sensors detect end-of-travel and positions of metallic objects without contact. Unlike traditional safety switches or RFID safety sensors, they require no special mating part, only standard M12 plugs. OSSD outputs can be used to easily connect the safe sensors to any desired safety processor.
As is the case with all Balluff safety switches and sensors, the inductive safety sensors can be directly connected to the Safety over I/O module, which bundles all signals and forwards them via an IO-Link master module to the safety controller. As a bonus, you benefit from all the advantages of an intelligent Industry 4.0 solution.
Magnetically Coded Safety Switches
Non-contact, magnetically-coded REED switches are outstanding for monitoring guard doors, especially in environments where contamination or dust is expected. The non-contact operating principle makes them insensitive to mechanical play, for example when doors settle or are imprecisely aligned. This makes the switches easy to install. With separate processing electronics, the safety switch can be used for applications up to PLe/SIL 3.
Magnetic Safety Encoder Systems
Magnetic safety encoder systems feature a safe incremental sin/cos interface and a safe absolute SSI or BiSS C interface. This makes them ideal for safety applications (certified by TÜV Rheinland). These systems meet the requirements of DIN EN ISO 13849-1:2015 (Machine Directive, Pld), IEC 61508:2010 (Functional Safety, SIL2) and EN IEC 61800-5-2:2007 (Safety Function, SIL2). A measuring length up to 48 m and high repeat accuracy (< 1 µm) makes them are highly versatile.
Transponder-Coded Safety Sensors
Non-contact, transponder-coded safety sensors offer tamper resistant, wear-free access security for guard doors and flaps. They are insensitive to contamination, vibration and mechanical play. These devices can be used reliably in applications up to PLe/SIL 3. Their compact size makes them easy to integrate, while an optional integrated magnetic clamp can be used to hold protection devices in position.For more information on Safety Switches from Balluff, as well as how Power Motion can help, please contact us.
