Tubular Electromagnet, 0.82" (21 mm) DIA X 0.77" (20 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)
