THE SQ-S200A Safety Switch, designed and manufactured in Australia by Jemtech , features fully sealed operation using RFID tag technology.
RFID technology means that the unit contains no mechanical parts and all switching is accomplished by sensing a unique tag embedded in a small key. Device outputs are self tested by the embedded dual-diverse-redundant microcontrollers.
These devices are fully sealed and have no spaces for materials to become embedded. This makes them suitable for use in food and pharmaceutical applications where cleanliness and the ability to hose equipment down is required.
Total lack of any mechanical actuation means the units have longer a service life than their mechanical counterparts. Self tested outputs also remove the need for additional redundant switches in high safety integrity applications.
The units are supplied with information about replacing existing mechanical switches and engineering new reliable safety systems.
