UNDK 20N7914/S35A, BAUMER, ultrasonic proximity sensor, 10–200mm, NPN, normally closed (NC), connector M8, IP67

UNDK 20N7914/S35A is an industrial Baumer ultrasonic sensor for non-contact evaluation of the presence of an object. Detection distance 10–200mm. Switching output NPN, normally closed (NC); connection connector M8.

Technical parameters – overview

Function and suitable use

Suitable applications include checking the presence of parts on a conveyor, the position of an object in a machine or non-contact monitoring of a limit distance. Before choosing, compare the working range, output circuit and geometry of the detected target.

How to choose the right variant

• Range: 10–200mm; design the target position within the declared interval, not on the basis of the series designation.
• Output: NPN, normally closed (NC); check compatibility with the control unit input.
• Mounting: rectangular version; observe the dimensions and recommended fixing.
• Wiring: The M8 connector makes sensor replacement easier; when ordering the mating part, check the number of pins and the wiring of the individual wires.
• Environment: protection IP67; verify suitability for specific contamination, temperatures or chemical influences according to the operating conditions.

Most frequent selection questions

What determines the minimum detection distance?

The near limit of the working range stated by the manufacturer is decisive; objects outside this range cannot automatically be considered reliably detectable.

What connection is needed?

For this model, the stated connection is connector M8. 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 closed (NC). Before connecting, compare it with the input type of the PLC or other control unit.
