This is included with the Cylinder, Threaded - M18 package for your convenience. Despite the operating temperature of -20°C~60°C, proximity sensors can function well. To achieve maximum efficiency, it is recommended that proximity sensors have their supply voltage set to 30V. To ensure that proximity sensors work properly, the rate should be set to 300kHz. To work well, the reed switch's internal contacts should pass 65mA current. A proximity sensor like this one is suitable for packages starting with Bulk.
