None Thermal CurrentI 5 A (10 A if A600) lth Rated Insulation Voltage 2500V Description Switching Current Voltage, Min. 5 mA 5V DC The Elf is a tongue-operated (or key-operated) safety interlock Utilization Category switch designed to fit at the leading edge of sliding, hinged or lift-off A600/AC-15 (Ue) 600V 500V 240V 120V guards. The Elf s unique miniature housing (only 75 x 25 x 29 mm (le) 1.2 A 1.4 A 3.0 A 6.0 A (2.95 x 0.98 x 1.14 in.)) makes it the smallest interlock currently DC-13 (Ue) 24V available. It is designed for smaller machines such as printers, copiers and domestic machinery which, until now, have been unable (le) 2 A to use safety interlocks due to space restrictions. With its dual entry Operating Characteristics slots and rotatable head, the versatile Elf can offer up to eight Break Contact Force, Min. 6 N (1.35 lbf) different actuator entry options. Actuation Speed, Max. 160 mm (6.29 in.)/s Operation of the switch is achieved through the insertion of a Actuation Frequency, Max. 2 cycles/s specially-profiled stainless-steel key that is permanently mounted to 150 mm (5.90 in.) 60 mm (2.36 in.) with the guard door. The semi-flexible key allows the Elf to be used on Operating Radius, Min GD2 kit, min. small-radii doors (60 mm or 2.36 in.). 6 Operating Life 100 mA load 1 x 10 operations The Elf is available with a variety of contact configurations, conduit Environmental entry types and connectors. It is sealed to IP67 (watertight and Enclosure Type Rating IP67 dustproof). A blanking plug is supplied for the unused key entry.
