Overview
General description
The coded non-contact switches Sense7 are designed to provide position interlock detection for moving gards.
They are designed to fit the leading edge of sliding, hinged or lift off machine guards. The actuator is fitted to the
moving part of the guard, and is aligned to the switch, placed on the frame of the guard. Its design makes it
advantageous to operate in environments that require the highest level of safety.

Function description
The magnetic switch is small in size, which makes it easy to position and hide on gates and hatches. Sense7 is
resistant to both dirt and water, and has no dust collecting cavities, which make it useful in environments where
hygiene is paramount. The non-contact coded safety switch has a long working life since no mechanical contact is
necessary for operation. The Sense7 has 2NC and 1NO contacts and a sensing distance to the actuator of 14mm.
It has a high tolerance to misalignment. Actuator is always delivered with the non-contact switch.
Depending on the environment where the switch will be used, different material can be chosen on the Sense7. The
basic version is in a full plastic body (polyester). In harsh applications as for food processing and chemical industry
there is a Sense7Z with a total rugged stainless steel 316 body. Both versions have an enclosure protection up to
IP69K and can be high pressure hosed with detergent at high temperature.
Warning! Application consideration must be given to the fixing of the actuator which has to be in a way that
prevents disassembly by easy means.
