We offer many choices for battery operated Ledex® solenoids which provide a full range of specific design benefits.
Refer to the selection overview charts below for a complete listing of solenoids suitable for battery operation.
Selecting the appropriate solenoid in terms of force or torque and response time, the coil size (awg or resistance) must be made in conjunction with a battery set that will both provide the required length of service (number of solenoid cycles) and will provide adequate solenoid performance at the battery voltage representing its end of life voltage.
To begin, determine the minimum voltage required for the solenoid to produce the specified force or torque for a particular coil resistance. Use this voltage to represent the end-of-life voltage of the battery set.
Refer to the manufacturer's data sheet to find the minimum, or end-of-life operating voltage per cell (typically this will be 1.0 volt for nickel cadmium and nickel metal hydride batteries). The solenoid wire size must then be selected to operate based upon this voltage times the number of cells in series.
