The TLµ series of optical sensors are based on a microprocessor and offer red/green or white LED emission with automatic selection, and can operate on all contrasts, also amongst same-coloured objects and backgrounds, presenting different surface treatments or workings. Various interchangeable lenses and fibre-optic versions are available.
The TLµµ series from Datasensor provides reliable contrast sensors with LED emission in red/green or white, suitable for detecting register marks and coloured references. The micro‑processor based settings include Teach‑in, Remote and Auto‑Set modes, and the sensors can be equipped with interchangeable 9 mm, 18 mm, 22 mm or 50 mm lenses as well as various fibre‑optic options.
Technical data cover power supply (10‑30 V DC), output type (selectable NPN or PNP), operating distances for each lens, response time (down to 25 µs), and environmental ratings (IP67, –10 °C to +55 °C). The catalogue also lists connection details, dimensions, and model‑specific codes for quick identification.
| Power supply | 10 – 30 V DC with reverse polarity protection |
|---|---|
| LED emission colors | Red 630 nm / Green 526 nm or White |
| Operating distance (9 mm lens) | 6 – 12 mm |
| Output type | Selectable NPN or PNP |
| Response time | ≤ 50 µs (≤ 25 µs for TL µ‑4/5xx versions) |
The sensors can emit red/green LEDs (630 nm/526 nm) or a white LED, allowing detection on all contrasts.
The output polarity (NPN or PNP) is selectable via an internal switch on each model.
The sensors operate from 10 V to 30 V DC and include reverse polarity protection.
Response time is up to 50 µs, with some versions achieving 25 µs.
