Generic E3F-DS30C4 Infrared Photoelectric Sensor Switch - NPN NO, DC 6-36V

The NPN NO output has three wires: Brown (V+), Blue (V- / GND), and Black (Output). Connect Brown to your DC supply positive (6-36V), Blue to supply negative/ground. The Black output wire will switch to ground (sink current) when an object is detected, pulling a PLC input or relay coil low. A pull-up resistor to V+ may be required on the Black wire for some microcontroller inputs.

No, the specified operating voltage range is 6-36V DC. Applying 5V may not power the internal circuitry correctly. For 5V microcontrollers, you must power the sensor with a separate 6-36V DC supply. The NPN output can interface with a 5V logic input if you use a suitable pull-up resistor to 5V on the sensor's output wire, ensuring the voltage does not exceed the sensor's supply rating.

The provided data does not specify the exact sensing distance or operating mode (through-beam, retro-reflective, or diffuse). The 'C4' suffix typically indicates specific sensing characteristics. For accurate specifications, consult the manufacturer's datasheet for the E3F-DS30 series. Generally, these industrial sensors offer ranges from a few centimeters to several meters depending on the model and reflector used.

The product description does not list an IP (Ingress Protection) rating. The housing offers basic protection but is not designed for direct exposure to rain or hose-down conditions. For outdoor or wet environments, select a sensor model with a specified IP67 or IP68 rating to ensure protection against dust and water ingress.
