Quantity adjustment on next page Series E-66-75  If the internal wire gauge for winding is predetermined or if the "voltage" is different from the above, enter the desired information in the above box labeled "Special Comments" and select the closest "voltage" and "duty cycle". C = Continuous (100%) Duty Cycle, Maximum On-Time = Infinite Approximate Input Power = 1 Watt Holding force against cold rolled steel with a thickness of: 0.125” (3.2 mm): 5.2 Lb (23 N) 0.063” (1.6 mm): 4.7 Lb (21 N) Available for voltages equal to or less than 36 Volts DC I = Intermittent (50%) Duty Cycle, Maximum On-Time = 300 Seconds Approximate Input Power = 2 Watts Holding force against cold rolled steel with a thickness of: 0.125” (3.2 mm): 6.7 Lb (30 N) 0.063” (1.6 mm): 6.2 Lb (28 N) Available for voltages equal to or less than 48 Volts DC L = Long Pulse (25%) Duty Cycle, Maximum On-Time = 120 Seconds Approximate Input Power = 4 Watts Holding force against cold rolled steel with a thickness of: 0.125” (3.2 mm): 9.1 Lb (40 N) 0.063” (1.6 mm): 8.6 Lb (38 N) P = Pulse (10%) Duty Cycle, Maximum On-Time = 30 Seconds Approximate Input Power = 10 Watts Holding force against cold rolled steel with a thickness of: 0.125” (3.2 mm): 11.9 Lb (53 N) 0.063” (1.6 mm): 11.5 Lb (51 N) Tubular Electromagnet, 0.75" (19 mm) DIA X 0.66" (17 mm) L. Mounting: 6-32 threaded hole. Minimum Heat Sink: Equivalent of 1.25” x 1.25" x 0.125" (32 mm x 32 mm x 3.2 mm) metal plate All values are at 25ºC. Duty Cycle= on time/(on time+off time) in one cycle of operation when voltage is being cycled on and off. V = R × I P = V × I = V² /R = R × I² V = input D.C. voltage (volts) R = electromagnet resistance (ohms) I = current used by electromagnet (amperes) P = input power to electromagnet (watts) Quantity adjustment on next page
