URAR 12N8914/S14H, BAUMER, ultrasonic retro-reflective sensor, 0–200mm, NPN, normally open (NO) / break function (NC), connector M12, IP67

URAR 12N8914/S14H is a Baumer retro-reflective ultrasonic sensor. Detection is set relative to a fixed reference surface, so a change in the monitored space can be detected. Position of the reference surface: 40–200mm. Declared detection range: 0–200mm. Connection: connector M12.

Technical parameters – overview

Function and suitable use

The retro-reflective version is chosen when a stable reference surface can be defined in the machine and its covering or a change in distance can be detected. The position and stability of the reflecting surface are essential for correct setting.

• The series design is intended for chemically more demanding environments; compatibility with a specific substance must nevertheless be assessed according to the sensor materials.

How to choose the right variant

• Range: 0–200mm; design the target position within the declared interval, not on the basis of the series designation.
• Output: NPN, normally open (NO) / break function (NC); check compatibility with the control unit input.
• Mounting: cylindrical version; observe the dimensions and recommended fixing.
• Wiring: The M12 connector is suitable for detachable machine wiring; verify the coding and number of contacts corresponding to this sensor.
• Environment: protection IP67; verify suitability for specific contamination, temperatures or chemical influences according to the operating conditions.

Most frequent selection questions

Does a retro-reflective sensor need a reference surface?

Yes. The principle of this version is based on a set reference surface; the declared range of its position must be respected.

What connection is needed?

For this model, the stated connection is connector M12. The mating part and pinout must be verified according to the manufacturer's version.

What output does this variant have?

The output circuit is NPN, normally open (NO) / break function (NC). Before connecting, compare it with the input type of the PLC or other control unit.
