HTM Perimeter and Area Guarding
Coil line, robotic cell, turret presses or similar perimeter guarding requirements may be protected by the HTM body protection light curtain system. A transmitter/receiver optics pair will detect front area access to the process area and initiate line shut down if personnel enter the processing zone. A second set may be added to guard the back side of the process, if required. Alternatively, mirrors and stands are available to provide 3 sided protection zones.
Safety system reset can be automatic or require manual reset via customer supplied key lock switch.
HTM Electronics 2, 3, or 4 beam category 4 control reliable body protection optics systems are available with 21.37″ to 48.93″ high protective zones. These perimeter guarding systems require a 24 vdc power supply and safety relay in addition to the optics. Scanning range is .5 to 25 meters.

MillerEdge Safety Mats for Auxiliary and Area Guarding
Safety mats, also known as safe guarding mats, provide reliable, cost-effective area guarding. Safety mats are presence sensing safety devices (PSSD) used to monitor protected areas. A single mat or multiple mats may be wired to a control device which is considered a category 4 safety device; however, the mats themselves are not category 4. Accordingly, mats are best suited for auxiliary guarding and area guarding where the likelihood of serious injury such as amputation, crushing, etc. does not exist.
MillerEdge Safety Mats
MillerEdge safe guarding mats consists of two conductive Alumaglas plates held apart by non-conductive compressible foam separators.
Upon mat activation, the non-conductive separator compresses, allowing the two plates to make contact. This increases the overall sensitivity of the mat surface.
