To make it easier for you, this Sensor is included with the Cylinder, Threaded - M30 package. The proximity sensors can work well with the operating temperature of -25°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 -25°C. The operating temperature of the proximity sensors cannot be higher than 70°C. The rate should be 500Hz to ensure that switch of the proximity sensors performs its function. The current that the reed switch's internal contacts pass should be 10mA to make the proximity sensors work well.
