The 3SE5 position switches differ from the previous series through the following new characteristics:
The modular structure of the product range allows a number of versions with a smaller number of bearing types for enclosures and operating mechanisms.
All actuators can be rotated around the axis in increments of 22.5°.
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.
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 three-pole contact blocks are available for all enclosure sizes.
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 2 x 2 mm contact opening is suitable for simultaneous shutdown and signaling, particularly in the elevator industry.
XL metal enclosures for accommodating two 2- or 3-pole contact blocks
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 figure for quick-connect technology).
