SIRIUS Mechanical Position and Safety Switches
Precise and reliable - our SIRIUS detecting devices are vigilant
There is a diversity of information in the field. To capture this correctly and precisely, you need devices you can rely on. A clear case for SIRIUS detecting devices – our comprehensive range for just about every application case at the field level.
The position switches score on reliable shutdown in the event of hazards, even under extreme environmental conditions. Machines and plants can be safety shut down in the event of faults or hazards.
The range of SIRIUS 3SE5 position switches encompasses both complete units and modular designs with which special versions can be assembled simply and quickly.
Advantages at a glance
Modular design offers high flexibility and low warehousing costs
Diverse combination options thanks to different contact elements, pulleys and plugs
Position switches are available in a metal or plastic enclosure in accordance with EN 50047 and EN 50041
Versions for extreme environmental conditions such as enhanced corrosion protection (ECP) or -40 °C versions
High-speed on-site diagnostics thanks to LED display
Integrated ASIsafe electronics in the basic enclosure
Position Switches SIRIUS 3SE5, 3SE2, 3SE3 (Standard)
Simple plug-in mounting for fast replacement of the drive heads.
The position switches score on standardized design and functionality. These facilitate selection of the right switches, also simplifying storage, installation and wiring. Our position switches are also convincing in just about all applications thanks to a host of new features:
Detection of hazardous machine part movements
Monitoring of protective devices with rotary joints such as swing doors, flaps, covers etc.
Monitoring of laterally sliding protective devices, such as sliding doors, protective guards, etc.
Faster and more accurate position sensing using short stroke element
The position switches score on compact design and modularity. The modularity is characterized by the fact that any enclosure can be combined with any drive. The position switches are available both as complete units and as modular systems.
Position switches also suitable for safety applications if they are marked with positive opening identifiers.
Frequently demanded complete units are offered both in plastic and metal enclosures.
The right solution comprising basic switch and drive can be selected with the modular system. Short installation times are guaranteed thanks to fast replacement of the drive heads.
Quick-connect technology reduces mounting times by up to 25 % with 31 mm plastic position switches
The compact position switches with metal enclosure specialize in:
Harsh environmental conditions IP67
Limited space conditions
All compact position switches are pre-assembled with molded cable of 2 or 5 m length. The switches are also available with M12 plug connectors.
Time savings in installation because already wired
Available in different drive versions
Impervious to electromagnetic interference
The open-type switches are suitable for restricted installation conditions in the control cabinet to IP20. They are equipped with two or three contact elements in the versions snap-action, slow-action or slow-action with overlapping.
Increased abrasion resistance thanks to metal plunger enables two directions of approach:
- Stroke direction - Lateral actuation at an angle of 30 degrees
The position switches are used for safeguarding doors and covers. The switch is secured on the door frame, and the actuator is secured on the door. Thanks to the combination of switch and multiple-coded actuator, the position switches have optimal tamper protection. In the secure state – in other words, when the protective door is closed – it forces the positive opening of the NC contacts.
Tamper protection possible thanks to a host of coded actuators
Integrated ASIsafe electronics in the enclosure
Fast on-site diagnostics thanks to LED display
If a locking mechanism for a protective door is required for securing the operating area of a robotic system, for example, position switches with separate actuators and additional electromagnetic solenoid interlocking are used. These ensure that the protective door is kept shut until it is safe to enter the operating area.
Increased safety and reliability due to high locking forces: 2600 N (metal enclosure); 1300 N (plastic enclosure)
Space savings in the control cabinet due to integration of ASIsafe and low current consumption ≤ 170 mA due to direct connection to the As-i network
Various additional unlocking variants ensure the right solution for all applications - Auxiliary release / with lock - Escape release - Emergency release
Minimized storage overhead made possible by limited 2x3 contact variance
The range of hinge switches with hollow or solid shafts supplements the range of position switches for monitoring swing doors and flaps. The solid keyed connection between the switch and safety door hinge provides maximum protection against tampering.
Tamper-proof monitoring of flaps and doors
Simple mounting using models with integrated hinges
Safe shutdown and reporting from a switching angle as low as 10 degrees
Connection with AS-Interface: system-wide flexibility
SIRIUS detecting devices are suitable for networked systems within your plant. A host of switches can be connected via AS-Interface. This keeps you flexible – even in large, wide-ranging plants. The operating state is indicated via the LED display on the AS-i devices. This facilitates troubleshooting and saves time.
Our new generation of switches enables simple and fast connection to the AS-i network thanks to:
Integration of ASIsafe
a M12 connector is used for connection to the AS-Interface system
Direct integration of the safety position switch with tumbler into the AS-i network means that the data cable has a current requirement of just ≤ 170 mA
Position switches and safety switches with AS-i
The entire range of position switches is available as 3SF1 position switches with integral ASIsafe electronics:
Standard position switches
Position switches with separate actuator
Position switches with tumbler
The 3SF1324-...-1BA4 position switches are optimally suited to series connections for protective door tumblers. As well as the ASIsafe standard, it complies with the high safety category SIL 2 / PL d and is equipped with special logic: the operator receives feedback from solenoids and now no longer has to open the protective door specially after unlocking the solenoids to bring the machine or plant back to the safe state. This enables fast restart after door enable
Need safe position switches? You've come to exactly the right place. Because our position switches and safety switches detect movement sequences and states in the field – safely. This makes them the first link in the safety chain. After detecting, they forward the signals safely to safe evaluation units such as safety relays, software-parameterizable safety relays, or fail-safe controllers. The switches offer the right solution depending on the hazard.
With a large number of position switches, personnel protection is ensured by positive opening of the NC contacts. The 3SE5 position switches with positive opening enable safety category SIL 1 / PL c.
Safety category SIL 2 / PL d can be achieved with just one safety switch.
Higher safety categories such as SIL 3 / PL e can be achieved by using combinations of switches. Depending on the requirements of the application, different switches can be combined.
