Detecting – SIRIUS Magnetically-operated switches

Used to monitor protective doors

SIRIUS Magnetically-operated switches are ideally suited to monitor protective doors. They operate contactlessly. The reed contacts in the switching element are actuated via a coded switching magnet and are therefore especially tamper-proof.

Product features of SIRIUS Magnetically-operated switches with evaluation unit

• System comprising magnet, switching element and evaluation unit
• Three different designs
• Monitoring of 1 to 8 protective doors with a single evaluation unit
• Cat. 4 according to EN 954-1
• Signal output for each connected protective door
• Manipulation-proof due to coded switching elements
• Due to high degree of protection, can also be used in extreme ambient conditions
• High operational reliability/safety

Expanded options with SIRIUS Magnetically-operated switches through ASIsafe

New: In conjunction with the AS-Interface ASIsafe 3RK modules, the magnetically-operated switches 3SE6605-2BA are approved for applications up to Cat. 4 according to EN 954-1.

Customer benefits

Efficient and cost-effective due to:

• Savings potential through monitoring of up to eight protective doors with a single evaluation unit
• Small footprint, simple mounting
• Concealed installation option

Detecting – SIRIUS Hinge switches

SIRIUS Hinge switches serve to monitor and protect hinged protective devices, such as doors and flaps.

Product features

• Positive opening of NC contacts according to IEC 947-5-1
• Applications up to Cat. 4 according to EN 954-1
• High contact reliability - even at 5V DC/1mA
• Suitable for ambient temperatures of -35° to +85°C
• High degree of protection, IP 65
• Versions for mounting with integrated hinges, on hinges, doors and flaps
• Extremely small opening angle:
• 4° with slow-action contact
• 5° or 15° with snap action contact

Customer benefits

Efficient and cost-effective through

• Manipulation-proof monitoring of flaps and doors
• Simple mounting
