PONO 18GM75-1000-I Ultrasonic Distance Sensor, 4~20mA Output, 12~30VDC, M12 Connector, IP67, Range: 60mm~1000mm

The standard pinout for this 4-20mA ultrasonic sensor with a 4-pin M12 connector is typically: Pin 1 = Power Supply (+V), Pin 2 = Not Used (NC), Pin 3 = Signal Output (4-20mA), Pin 4 = Power Supply Ground (0V). Always refer to the specific datasheet for the confirmed wiring diagram before connection.

The teach-in function allows you to set the 4mA and 20mA output points corresponding to specific distances. Typically, you place a target at the minimum desired range, trigger the teach-in sequence (often via a button or a specific wiring sequence), then repeat with the target at the maximum range. The sensor stores these points, scaling its output linearly between them.

Yes, the IP67 rating signifies the sensor is dust-tight and can withstand temporary immersion in water up to 1 meter for 30 minutes. It is suitable for use in damp industrial environments, washdown areas, and outdoors, provided it is not subjected to continuous high-pressure water jets or permanent submersion.

A 4-20mA current loop is highly resistant to voltage drop and interference, allowing for long cable runs. Using standard 18-22 AWG shielded twisted-pair cable, reliable transmission over distances of 1000 meters or more is typically achievable, depending on wire gauge and loop voltage compliance.
