Sick KT5W-2P2116 Contrast Sensor PNP
Rectangular contrast sensor with RGB LED, 10 mm sensing distance, PNP output, M12 connector and IP67 enclosure
- Precise colour detection with 10 mm sensing distance
- Fast 10 kHz switching frequency for high-speed lines
- Quick setup via teach-in button with 25 ms retention
- Rugged IP67 zinc housing withstands harsh environments
- Flexible 10–30 V DC supply with PNP output
Industrial contrast sensor for automated sorting
The Sick KT5W-2P2116 detects colour contrast at a 10 mm sensing distance with ± 3 mm tolerance. Its RGB LED emits at 470 nm, 525 nm and 640 nm from exchangeable long or short housing sides. A 4.2 mm x 1.2 mm horizontal light spot suits mark detection on packaging or print lines. The zinc diecast housing weighs 400 g and meets IP67.
Teach-in setup with M12 connector
Press the teach-in button for static 2-point teach-in; the ET input accepts PNP levels with 25 ms retention in non-volatile memory. Connect via a 5-pin male M12 connector to a 10 V DC … 30 V DC supply with < 80 mA draw. Reverse-polarity and short-circuit protection guard the PNP output rated at 100 mA. Verify cable pin-out before power-up to avoid wiring errors.
Switching speed and voltage limits
The sensor switches at 10 kHz with a 50 µs response time, limiting use to high-speed registration marks rather than continuous web inspection. Supply ripple must stay within 5 Vpp for stable operation. Protection class II and IP67 suit harsh environments but do not replace functional safety certification where required. Output voltage drops to VS–2 V at HIGH and near 0 V at LOW.

Questions about this item
How can I confirm the sensor is operating correctly after mounting it at the 10 mm sensing distance?
After a static 2-point teach-in via the button, verify the PNP output switches HIGH at VS minus 2 V and LOW near 0 V with a response time of 50 µs at 10 kHz switching frequency.
What accessories are included and what must be purchased separately for the M12 5-pin connection?
The sensor housing weighs 400 g with zinc diecast construction and IP67 rating; a compatible M12 5-pin female cable or connector must be bought separately for power and signal wiring.
Which teach-in mode should I select for reliable contrast detection on the 4.2 mm by 1.2 mm light spot?
The sensor uses static 2-point teach-in only; press the teach button for the mark and background positions to store the threshold in non-volatile memory with 25 ms retention.
