PTC Thermal sensor

LMA actuator integrates Thermal switch (normally closed, open at maximum winding temperature) or PTC600 thermal sensor. This thermal sensor is composed by 3 x PTC series connected mounted in each primary part of the integrated linear motor. In order to map the PTC curve inside the drive please use DN44082 thermistor type curve, with 1800 Ohm of thermistor reset threshold and 3300 ohm of thermistor trip threshold.
