Safety Edges & Bumpers Safety Edges Safety Edges (SGE & SCS Series Profiles) Profile materials NBR (SCS series only), EPDM or TPE Available in six sizes for SGE Series and two sizes for SCS Series Description Safety edges are used on edges of guards and gates at possible crushing or shearing points. They are used on gates, machines, and handling equipment to protect people and equip- ment. Our SGE Series safety edges use the innovative design of co-extruded safety contact as an integral part of the safety edge. Aluminum Mounting A complete unit consists of an aluminum mounting channel, the Channel safety contact, and the safety edge. The special shapes of the EPDM, TPE, or NBR rubber profiles protect the safety contact from Molded Wiring Plug damage and allows actuation angles to exceed 90 degrees. The last safety edge in a serial connection is terminated with a SGE Extruded Profile resistor, which is continuously monitored by the controller. This al- with Integrated lows the entire circuit to be monitored for shorts and wire breaks. Co-Extruded Safety Contact The SGE Design SGE series profiles are patented and offer improved technical characteristics with fewer components. Inside the safety edge is the co-extruded switching unit, which consists of two conduc- Molded End Cap tive rubber extrusions inside the chamber and a high-isolating with Cable Entry material EPDM or TPE outer. Inside of each conductive rubber and Water Drain extrusion is a copper wire with low-resistance evaluation. The molded wiring plug at each end ensures the constant contact of the two conductive rubber extrusions of the switching unit. The end caps seal and protect the safety contact from dirt and water The SCS Design ingression. This innovative design significantly reduces assembly time, saving both time and money. In SCS series safety edges, the safety contact is inserted into the switching chamber of the safety edge. The two ends Important features of the SGE profile: are then sealed with Conducting Fast, accurate response even during lateral application of force a permanently elastic Contact Surfaces Fewer components required for complete assembly adhesive and end Fast and easy assembly caps to keep the unit Integrated water drain (some models) 0.24 watertight. Reduced weight 6 All SCS series safety Insulating edges are available in Outer Sleeve The SGE profile is currently available in six sizes from 8 mm NBR only. to 65 mm in height. Profiles are available with sealing lips for Reinforced applications such as doors. 0.71 Copper Wire 18 1 www.omron247.comSafety Edges Safety Edges & Bumpers Specifications SGE-245/ SGE-365 SGEY-365 SGE-88 SGE-1510 SGE-125 SGE-225 SGE-245L (Black) (Yellow) SCS-2525 SCS-2540 Material: EPDM TPE TPE EPDM EPDM EPDM TPE NBR NBR Mounting: DBL Side Integrated SCA-15-9 SCA-25/25L SCA-25/25L SCA-35/35L SCA-35/35L SCA-25/25L SCA-25/25L Tape Angle on Profile or SCA-15-9 Material Hardness: 68 Shore A 65 Shore A 65 Shore A 68 Shore A 68 Shore A 68 Shore A 68 Shore A 68 Shore A 68 Shore A Max.
