The MG4600 are available in 20 mm, 30 mm and 50 mm resolution, provide protected heights from 17.13 inches (435 mm) to 82.52 inches (2086 mm) depending on system resolution, and offer a 65 foot (20 meter) sensing range. Control reliable circuitry eliminates the need for a separate controller, and patented Individual Beam Indicators simplify alignment. Additional features include field-replaceable safety relays and weld shield, Floating Blanking to block up to two beams anywhere in the zone, and Exact Channel Select to permanently block selected beams where machine parts will obstruct a portion of the zone.
Options include MPCE monitoring for control reliability, MTS (Machine Test Signal) for verifying proper operation of safety outputs, and DeviceNet interface for communication of non-safety related data between the MG4600, the main machine controller, and other nodes residing on this fieldbus. Optional Automatic Start and Start/Restart Interlock modes allow the MG4600 to be configured for either point-of-operation or perimeter guarding.
