URAM 50P6121, BAUMER, ultrasonic retro-reflective sensor, 0–3000mm, PNP, normally open (NO), cable 2m, IP67

URAM 50P6121 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: 600–3000mm. Declared detection range: 0–3000mm. Connection: cable 2m.

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 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.
• Stated multiplex version: on request. The setting must correspond to the specific application.

How to choose the right variant

• Range: 0–3000mm; 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.

Difference from a related model

Compared with the variant URAM 50P6121/S14 this model differs in the parameter connection: zde cable 2m, for variant URAM 50P6121/S14 connector M12. This is decisive when choosing the correct version.

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.

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.
