To make it easier for you, this Sensor is included with the Module 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 30V for maximum efficiency. The rate should be 224kHz to ensure that switch of the proximity sensors performs its function. The current that the reed switch's internal contacts pass should be 40mA to make the proximity sensors work well. This proximity sensor is suitable for Bulk package.
