Industrial contrast sensor
The Sick KTM-WN11181P is a rectangular contrast sensor with an RGB LED light source emitting at 470 nm, 525 nm and 625 nm. It detects marks at a 12.5 mm sensing distance with a ± 3 mm tolerance. The 1.5 mm x 6.5 mm vertical light spot suits precise registration tasks on packaging or print lines.
Sensing capacity and limits
A 15 kHz switching frequency and 32 µs response time handle high-speed web or conveyor applications. NPN light/dark switching supports 50 mA output current. Teach-in via button or dynamic ET input stores settings in non-volatile memory with a 28 ms retention time. Operation stops beyond the 12.5 mm range or if supply voltage falls outside 12 V DC to 24 V DC.
Upgrade context
This unit replaces older contrast sensors that lack RGB discrimination or teach-in flexibility. The jump is worthwhile when an application needs multi-wavelength detection at 15 kHz in a compact ABS housing rated IP67. It is not for buyers who require analogue output, longer sensing distances or PNP switching logic.

Questions about this item
Will the 12.5 mm sensing distance and M8 4-pin connector work with my existing 24 V DC control cabinet wiring?
Yes, the sensor operates on 12 V DC to 24 V DC with an M8 4-pin male connector and NPN output, compatible with standard 24 V DC PLC inputs.
How can I verify the 15 kHz switching frequency is performing correctly after installation?
Use the teach-in button for 2-point static or dynamic setup; the output toggles at up to 15 kHz with a 32 µs response time, confirm with a frequency counter on the NPN signal.
Does the box include the M8 4-pin mating cable or must I order it separately?
The sensor ships with the M8 4-pin male connector on the housing; a matching female cable assembly is not included and must be purchased separately.
