Rite-Hite Machine Guarding introduces the Guardian Defender™, the industry's most effective machine guarding device yet. Designed with the latest regulations and most demanding manufacturing process in mind, the Guardian Defender is the ideal device for safeguarding machinery in many manufacturing environments. Anywhere that a machine operator interfaces with a machine, robot or process is an ideal application for the Guardian Defender.
Visibly safer than light curtains, the Guardian Defender combines safety interlock switches/controls capable of achieving up to PLe, Category 4 level safety with a movable physical barrier restricting access to dangerous machine movement while at the same time containing process driving hazards such as weld flash/sparks, flying debris, mist, spray and other containment and exposures.
Features & Benefits
- Protects operators from application driven hazards while restricting access from machine/robot operation both physically and electronically with optional safety rated switches and controls.
