Module includes it for your convenience. A temperature of -25°C~70°C is suitable for the operation of proximity sensors. It has a pin count of 3. In order for the proximity sensors to perform their function, the rate must be 600Hz. If the proximity sensors are to function properly, the current passing through the reed switch's internal contacts should be 100mA. In DC circuits, proximity sensors can be exposed to a voltage of 30V without being damaged. As long as the current of the proximity sensors in the DC circuit does not fall below 10V, it is dangerous. In order to maximize efficiency, you should set this electronic part's current to 15mA.
