Non-Contact Safety Switches

No margin for manipulation

Non-Contact Safety Switch SIRIUS 3SE63, RFID

The new electronic non-contact safety switch for protective equipment is based on non-contact RFID transponder technology and offers comprehensive protection against interference, manipulation and defeat. The rugged and vibration-proof safety switch with cleaning agent-resistant plastic enclosure and high degree of protection up to IP69K is dimensioned for a long service life and application under extreme ambient conditions. It supports wear-free switching and covers a broad application area: From difficult to adjust, down to frequently opened and closed protective hoods, flaps or doors.

Highlights:

Reliable monitoring of protective equipment on highest safety level – even with the application of multiple switches connected in series.

Advantages at a glance:

  • Comprehensive protection against interference and manipulation thanks to diverse coding versions

  • Highest safety level thanks to compatibility with safety evaluation units (e.g. SIMATIC PLC, SIRIUS 3TK28 or 3RK3)

  • Multiple RFID switches can be jointly connected in the same safety circuit as they feature integrated cross-fault, wire breakage and external voltage monitoring functions

  • Low investment costs as only 1 switch is required for safety applications up to PL e in accordance with EN 13849-1 and SIL 3 in accordance with IEC 61508/62061

  • Long service life thanks to wear-free switching

  • Increased system availability thanks to comprehensive diagnostic functions

  • Rugged and resistant to cleaning agents: Degree of protection up to IP69K

  • Vibration-proof thanks to optional magnetic latching  up to 18N

  • Ideal applicability for metal-processing machines and systems thanks to non-magnetic technology (RFID)

  • Easy mounting and maintenance:
    - Universal fastening holes: Mountable on any side
    - Applicability as limit stop with small to medium-sized doors
    - Rapid adjustability thanks to greater switching offset compared to mechanical
      switches and limit range detection via LED display on the switch => improved
      mounting and sagging tolerance
    - Easy replaceability – thanks to standard inside micrometer and boreholing as with
      magnetically operated switches  SIRIUS 3SE66/67


3SE66, 3SE67 Standard range

Non-Contact Safety Switch SIRIUS 3SE66, 3SE67, Magnetic

The magnetically operated switch SIRIUS 3SE6 is designed for attachment to movable protective equipment (hoods, flaps, doors, etc.). Evaluation is realized via a safety relay or connection to a bus system. The non-contact magnetically operated safety switches 3SE66 are characterized by their enclosed design with high degree of protection IP67. They are therefore particularly suited for areas subject to contamination, cleaning or disinfection conditions.

3SE66, 3SE67 Supplementary range

Advantages at a glance:

  • Tamper-proof protective door monitoring

  • Small footprint thanks to minimal housing dimensions

  • SIL 3 acc. to IEC 61508, IEC 62061 and PL e acc. to EN ISO 13849-1 achievable with single switch pair
