Sensors and sensing equipment, Safety switches & accessories
RFSS are standalone, non-contact RFID safety switches. With 2NO 1NC contacts that can switch 400mA at 24Vdc, with tamper proof RFID switching, the RFSS is suitable for use with most safety relays. A dual color built in LED helps the operator to quickly diagnose any faults. The RFSS safety switches are available with 2, 3 or 5 meter pre-wired cables which are fully sealed and suitable for use in most wet / harsh environments.
Features
- Security contact: 2 x redundant NO 200mA/24V
- Auxiliary diagnostics contact: 1 x 400mA PNP
- Detection encoding: inviolable multi-code
- Indicator: LED indicates code recognition
- Pre-wired system: 2, 3 or 5 meter cable
- Protective class: IP 67
- Controls the position of safety doors/casings with RFID encoding
- Level of performance with safety controller is up to PLe
- Safety class without an external controller is SIL3 (ISO 13849-1)
Applications
- Can forming and filling (aluminum, steel and plastic)
- Packaging equipment
- Pick and place assembly equipment
