Sick KT3L-N3216 Contrast Sensor
The Sick KT3L-N3216 is a rectangular contrast sensor with NPN switching output designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply and draws less than 35 mA. The housing measures 12 mm by 40 mm by 22 mm and weighs 11 g.
40 mm sensing with laser teach-in
The sensor uses a red laser at 655 nm producing a 1 mm by 2 mm vertical light spot. Operating distance ranges from 20 mm to 60 mm with a ± 20 mm tolerance on the 40 mm nominal sensing distance. A teach-in button enables static 2-point teach-in and retention time is 25 ms with non-volatile memory.
IP67 ABS housing with M12 connector
The ABS housing provides IP67 enclosure rating and protection class II. Circuit protection covers reverse polarity, output short-circuit and interference pulse suppression. Connection is via a male M12 4-pin connector. Switching frequency reaches 1.5 kHz with a 400 µs response time and maximum output current of 100 mA.

Questions about this item
Should I choose the NPN output version or is there a PNP alternative for this sensor?
This specific model provides an NPN switching output rated at 100 mA maximum; a PNP version would carry a different part number.
How does the 1.5 kHz switching frequency perform when the sensor is mounted on a production line?
The sensor switches at up to 1.5 kHz with a 400 µs response time, allowing reliable detection of contrast marks on materials moving at typical line speeds.
What does the M12 4-pin connector limit in terms of wiring and voltage range?
The M12 4-pin connector carries the 10-30 V DC supply and NPN output, supporting the specified 35 mA current draw and 100 mA load.
