Feature
- The modular design of the product range allows a number of versions with a smaller number of bearing types for enclosures and operating mechanisms.
- All operating mechanisms can be rotated around the axis in increments of 22.5° (see Overview → Mounting).
- Rounded and roller plungers according to EN 50041 with 3 mm overtravel (total travel 9 mm) for greater tolerance when switching.
- All enclosure sizes – now also including the small enclosure 31-mm wide – are optionally available with an LED signaling indicator (see Overview → Optional LED indicators).
- All enclosure variants have an integrated chlorinated rubber diaphragm for high functional safety in cold and aggressive environments.
- All contact blocks are replaceable (see Accessories and spare parts).
- The 3-pole contact blocks are available for all enclosure sizes (see Overview → Diverse contact types).
- Elements with 1 NO + 2 NC slow-action contacts with make-before-break and 2 NO + 1 NC
- The short-stroke contact block 1 NO + 1 NC improves the precision of the switching operation through a reduced actuation path.
- The contact block with 1 NO + 1 NC snap-action contacts with a contact distance of 2 x 2 mm is suitable for simultaneous shutdown and signaling, particularly in the elevator industry.
- XL metal enclosures for accommodating two 2- or 3-pole contact blocks
- Versions with plugs for safe and fast connection, e.g. to fail-safe field modules of SIMATIC ET 200eco PN or SIMATIC ET 200AL
- The plastic enclosures with a width of 31 mm have simple and fast wiring equipment, making it possible to achieve time savings of approx. 20 to 25% when connecting (see Overview → Quick-connect technology).
- The ASIsafe electronics are integrated in the enclosure for the versions with AS‑Interface connection (see SIRIUS 3SF1 mechanical safety switches for AS-Interface); an additional adapter is not required.
