The LD46-UL-755 is a midi-format luminescence mark reader that emits UV light (375 nm LED) and detects reflected visible light from fluorescent objects or marks, independent of background color. It offers a nominal sensing distance of 40 mm (practical range 10–50 mm), 2 kHz switching frequency, and 250 µs response time. Outputs include selectable NPN/PNP digital (dark/light) and a 0–5 V analog channel, all accessible via a 5-pole M12 connector. The aluminium/glass housing is rated IP67 with an operating temperature of –10 to +55 °C and teach-in sensitivity adjustment via push-buttons.
