STI Safety Light Curtain OMRON STI Safety Light Curtains From compact models designed for machine locations where space is tight, to larger, robust light curtains powerful enough to guard large perimeters. Omron STI offers you a choice, because when it comes to automation safeguarding, one size does not fit all.


STI Safety Mat  OMRON STI Safety Mats An Omron STI Universal Safety Mat system (UM series safety mat combined with an MC3, MC4, or MC6) offers a simple method for guarding personnel around hazardous machines. A safety mat system offers freedom, flexibility, and reduced operator fatigue when compared with traditional guarding methods such as interlocked fences, pullback restraints or perimeter barriers. Full visibility of and access to the work area is maintained.


STI Safety Interlock Switches  OMRON STI Safety Interlock Switches Designed to work together with hinged, sliding, or lift-off guards and barriers. When the guard is opened, the power supply to the machine is disconnected.


STI Laser Scanner  OMRON STI Safety Laser Scanner Intrusion indicators immediately identify where the safety zone is encroached.


STI Perimeter Access Guarding  OMRON STI Perimeter Access Guarding Single-Beam Devices, Multi-Beam Devices, and Accessories


STI Safety Contact Strips  OMRON STI Safety Contact Strips & Bumpers The safety edge or safety bumper are flexible strips which can be fixed to the edge of a moving part such as a machine table or powered door where there is a risk of a crushing or shearing hazard. If the moving part that includes the safety edge or bumper strikes operator (or vice versa) the flexible safety edge is depressed and will send a signal to the power source to stop.


STI Force Guided Relays OMRON STI Force Guided Relays Force-guided (or positively-guided) relays have contacts that are mechanically interlocked such that two contacts on the relays will not contradict each other, even in the event that the relay welds. Force-guided relays have contacts that are force-guided/mechanically linked conforming to IEC60947-1-1 as required for use in safety-related control systems.


STI Safety Relay  OMRON STI Safety Monitoring Relays Control reliability is mandated in U.S. and European standards for safety implemented circuits. These criteria can be met by using redundant safety-rated device outputs in conjunction with a safety relay. Safety relays range in function from stop motion detection to 2 -hand palm button control, to dual channel input units with time-delayed outputs that provide conformity to ANSI B11.19, Section 5.1.  All safety relays carry the CE mark and are UL and C-UL listed.


STI Power Relays  OMRON STI Power Relays with Mirror Contacts All materials used are compliant wit the RoHS Directive.


STI Two Hand Control  OMRON STI Two-Hand Control TouchStart™ capacitive palm switches for two hand control applications actuate with a soft touch. No physical pressure is required, and they are sensitive enough to work even when an operator is wearing gloves.
