SICK NT8-04612 1005993 Contrast Detector

The SICK NT8-04612 (part 1005993) is a compact contrast sensor from the NT8 family that detects light–dark contrasts using a white light source with a sensing distance of ≤ 9 mm and a light spot measuring 1.5 mm by 3.5 mm. Its rectangular housing (76 mm wide × 30 mm high × 58.8 mm deep) supports light emission from the long and short sides with exchangeable light-spot orientation and a vertical light-spot configuration. Electrical characteristics include a 10–30 V DC supply for the electronics (< 50 mA), a separate lamp supply of 4.5 V ± 10% at 840 mA, a switching frequency up to 10 kHz, a response time > 50 µs, and an NPN switching output capable of up to 200 mA (with a 1:1 light/dark ratio). The unit is delivered with a 5-wire cable and male connector for straightforward integration and is cataloged as NT8-04612, part number 1005993, in SICK’s contrast sensor lineup.
