This is included in the Module package to make it easier for you to use. At temperatures of -40°C~70°C, proximity sensors work well. It is recommended that the supply voltage of proximity sensors be set to 30V to achieve maximum efficiency. Ensure that the proximity sensor switch performs its function by setting the rate to 224kHz. In order for proximity sensors to work properly, the reed switch's internal contacts should pass 40mA current. An appropriate package for this proximity sensor is Bulk.
