Sick Device columns with external grooves
No reviews yet.
Device columns from SICK are used wherever there are no mounting options for opto-electronic protective devices. The opto-electronic protective devices are mounted on free-standing device columns to provide protection at machining centers and material locks. For locks that convey material automatically, a muting system is frequently used for protection. The stable device columns with two grooves on the outside, working together with mounting arms, brackets and protective plates, ensure flexible and straightforward attachment of the muting sensors. Pre-mounted kits significantly reduce order volume and the time needed for on-site installation. Suitable accessories such as compensating plates and steel anchors simplify installation in the floor and alignment of the device columns.

Sick Safety light curtains miniTwin
No reviews yet.
For more than 10 years, SICK has been writing a success story with the miniTwin – the safety light curtain in miniature format – in hazardous point protection for finger and hand protection. Its two twin sticks, in which the sender and receiver are installed symmetrically in a compact housing for the first time, have received several awards. One of the Twin-Sticks is mounted opposite the other one and rotated by 180 degrees. This creates a safe protective field. The miniature design of the miniTwin, the option of cascading it and its different protective field heights save production space and enable small safety distances. At the same time, this mini device achieves great things: it functions perfectly, even when subjected to very strong shocks and vibrations and temperatures down to –20° Celsius.
