The Pauly ET103/2000 is an adjustable reflex‑scanner featuring active background response suppression and a selectable scanning depth. The device uses a green LED source and a DIANA digital‑analog indicator to display signal levels. Scanning distance is set by a screw under the PG1 cover, allowing precise adjustment of the maximum usable range.
The scanner operates from a 24 VDC supply (40 mA without load) and provides a pnp 60 mA output with optional optocoupler protection. It is housed in an aluminum‑cast enclosure (≈1000 g) with an IP65 protection rating and can operate from –30 °C to +65 °C. Various connector options and accessories are available, including different plug types and cooling‑water flanges.

|---|---|
| Weight | ≈ 1000 g |
| Electrical connection | 3+1 pin Plug stH4 |
| Supply voltage | 24 VDC / 40 mA (no load) |
| Output type | PNP 60 mA, short‑circuit protected |

Turn the screw located under the PG1 cover clockwise; this increases the scanning distance L.
It is the distance L + 5 % beyond which the scanner will not reliably detect diffuse reflecting surfaces.
The delay interval can be set between 0 and about 10 seconds, with optional preset values of 1 s, 3 s, and 20 s on request.
