Sick KT5W-2N1116 Contrast Sensor NPN
The Sick KT5W-2N1116 is a rectangular contrast sensor with an NPN switching output designed for industrial detection tasks. It uses an RGB LED light source with wavelengths of 470 nm, 525 nm and 640 nm to distinguish surface marks. The sensor offers a 10 mm sensing distance with a ±3 mm tolerance and a 1.2 mm by 4.2 mm vertical light spot. Teach-in adjustment is performed via a static two-point button on the zinc diecast housing.
Installation checks for KT5W-2N1116
Verify that your control system accepts an NPN output with a HIGH level near the supply voltage and a LOW level at 2 V. The unit requires a 10 V to 30 V DC supply with ripple below 5 Vpp and draws under 80 mA. Confirm the M12 5-pin male connector matches your cabling and that the IP67 enclosure rating suits the environment. The teach-in input expects less than 2 V for teaching and 10 V to UV for run mode with a 25 ms retention time.
Upgrade from basic photoelectric sensors
This sensor replaces simple through-beam or diffuse units when colour or contrast differentiation is required at close range. The 10 kHz switching frequency and 50 µs response time support high-speed production lines. The jump is worthwhile when print marks, coloured labels or grey-scale variations must be detected reliably at 10 mm. It is not for applications needing longer sensing distances or analog output signals.

Questions about this item
Does the sensor ship with an M12 cable or do I need to buy one separately?
The unit has a 5-pin M12 male connector; a matching cable is not included and must be purchased separately.
Should I choose the NPN or PNP version for my PLC input card?
This model provides an NPN switching output (HIGH ≈ supply voltage, LOW ≤ 2 V) with a maximum load of 100 mA.
What does the 10 kHz switching frequency mean for my packaging line speed?
A 50 µs response time and 10 kHz switching frequency allow reliable detection of marks moving at high web speeds.
