To make it easier for you, this Sensor is included with the Cylinder, Threaded - M18 package. The proximity sensors can work well with the operating temperature of -40°C~70°C. This electronic component has 4 pins. It is recommended that the supply voltage of proximity sensors be set to 24V for maximum efficiency. The lowest operating temperature of the proximity sensors can be reached -40°C. The operating temperature of the proximity sensors cannot be higher than 70°C. The rate should be 400Hz to ensure that switch of the proximity sensors performs its function. The current that the reed switch's internal contacts pass should be 200mA to make the proximity sensors work well. The maximum voltage of 32V can be applied to the proximity sensors without damage in DC circuit. The current of the proximity sensors in the DC circuit should not be lower than 10V, otherwise, it will be dangerous. If you want to maximize efficiency, you should set the current of this electronic part to 10mA.
