To make it easier for you, this Sensor is included with the Cylinder, Threaded - M5 package. It is possible for proximity sensors to operate effectively at temperatures below -25°C~70°C. To achieve maximum efficiency, it is recommended that proximity sensors have their supply voltage set to 24V. Proximity sensors can operate at temperatures as low as -25°C. A proximity sensor's operating temperature cannot exceed 70°C. In order to ensure the proximity sensors work correctly, the rate must be set to 1kHz. In order for proximity sensors to work properly, the reed switch's internal contacts should pass 15mA current.
