It comes with the Module package to make it easier for you. Operating temperatures of -25°C~85°C can be suitable for proximity sensors. Electronic components have 4 pins. In order to achieve maximum efficiency, proximity sensors should be supplied with a voltage of 30V. To ensure that the proximity sensor works, the rate should be 150Hz. Reed switches' internal contacts should pass 200mA current to make proximity sensors work. A voltage of 30V can be applied to the proximity sensors in DC circuits without the proximity sensors being damaged. If the proximity sensors are connected to a DC circuit, the current should not be lower than 10V, otherwise, it could result in danger.
