UNAM 50P1721, BAUMER, ultrasonic proximity sensor, 350–2500mm, PNP, normally open (NO), cable 2m, IP67

UNAM 50P1721 is an industrial Baumer ultrasonic sensor for non-contact evaluation of the presence of an object. Detection distance 350–2500mm. Switching output PNP, normally open (NO); connection cable 2m.

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.

• The advantage of this variant is a range intended for more distant targets; for stable detection, the working limits of the range must be observed.
• The manufacturer states synchronisation for this model: yes. When several sensors operate simultaneously, verify the recommended wiring.

How to choose the right variant

• Range: 350–2500mm; design the target position within the declared interval, not on the basis of the series designation.
• Output: PNP, normally open (NO); check compatibility with the control unit input.
• Mounting: cylindrical version; observe the dimensions and recommended fixing.
• Wiring: The cable version allows direct routing to the switchboard. During mounting, verify the cable length, strain relief and suitable cable protection.
• 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.

Jde o cableovou variantu?

Yes. The connection of this model is cable 2m. When designing the cable route, take into account the length and mechanical protection of the line.

What output does this variant have?

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