Part 1

What is a photoelectric contrast sensor?

A photoelectric contrast sensor shines light on a surface and measures how much comes back. A dark printed mark reflects less light than the lighter background around it, so the sensor switches its output every time a mark passes. This is why a contrast sensor is also called a registration mark sensor or colour mark sensor: it keeps cutting, sealing and printing in register with the print on the material.

The TLµ-515C contrast sensor belongs to Datalogic's compact TLµ family. The white LED works across a wide range of colours, so one sensor covers most jobs without changing the light source.

Why choose the Datalogic TLµ-515C sensor

  • Reliable mark reading: white light handles colour marks on printed film, foil and paper
  • Fast setup: teach the mark and background with the buttons, or remotely from the PLC
  • Compact and rugged: metal housing with IP67 protection for washdown and dusty areas
  • Easy wiring: standard M12 connector and PNP output for most Indian machine PLCs
  • Genuine replacement: direct match for older Datasensor TLu-515C units
Part 4

Typical applications of this industrial contrast sensor

  • Form-fill-seal (FFS) and flow wrap packaging machines
  • Pouch and sachet machines: cutting on the print mark
  • Label applicators and labelling machines
  • Printing, slitting and rewinding of laminates
  • Carton and tube marking, tea, spice, pharma and FMCG packaging
Part 5

TLµ-515C wiring and setup tips

Connect the M12 connector to a 10–30 V DC supply and wire the PNP output to the PLC or machine controller input. Mount the sensor about 9 mm from the material, roughly perpendicular to the surface, so the light spot sits on the mark track. Run teach-in on the mark and then on the background, and check the output LED as material moves past. For glossy film, tilt the sensor a few degrees to avoid direct reflections.

FAQ

Frequently asked questions

Is the TLµ-515C a contrast sensor or a colour mark sensor?

Both terms describe the same job. The Datalogic TLµ-515C is a photoelectric contrast sensor that detects printed registration marks (colour marks) by the difference in reflected light between the mark and the background.

What is the order code of the Datalogic TLµ-515C?

The Datalogic order code is 954151360. Quote both the model name and this code when you send an enquiry so you get exactly the right version.

What light source does the TLµ-515C use?

It uses white LED emission, which handles a wide range of mark and background colour combinations on printed film, labels and cartons.

What is the sensing distance?

The TLµ-515C works at a short fixed distance of about 9 mm from the target, which is typical for registration mark sensors on packaging machines.

What output and connection does it have?

A PNP switching output on an M12 connector, powered from 10–30 V DC.

How is it set up?

Using teach-in: you teach the mark and the background with the push-buttons on the sensor, or remotely through the cable.

Do you supply the TLµ-515C across India?

Yes. Industrypapa is a Datalogic sensor distributor in India with stock, GST invoice and pan-India dispatch.

Can I replace an old Datasensor TLu-515C with this model?

TLu-515C and TLµ-515C refer to the same Datalogic (formerly Datasensor) model. Share the label photo of your old sensor and we will confirm the match.
