*1. TPE: Thermoplastic Elastomer
      EPDM: Ethylene Propylene Rubber
*2. Values of actuation distance and actuation force are characteristic values tested according to EN 1760-2 using a test
       object of ϕ80 mm and actuating point C3 under a test temperature of 20°C and test speed v = 10 mm/s. Refer to
       “Characteristics” on Catalog for details.
*3. There is an inactive region (including an end cap) in both ends of the safety edge.
      2617_sp_2
*4. The SGE-225 can be used for finger protection.The actuation force is 20 N when the SGE-225 is used for finger
       protection.
       (Characteristic values tested according to EN 1760-2 using a test object of ϕ20 mm and actuating point C3 under a
       test temperature of 20°C and test speed v = 10 mm/s)
