Industrial Photoelectric Sensor for Automation
The Sick NT6-N112 is a rectangular photoelectric switch sensor designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply voltage with NPN switching output. The sensor uses a red and green LED light source at a 560 nm wavelength. It offers a sensing distance of 9 mm with a ± 2 mm tolerance.
Low Power Consumption and Fast Response
Power consumption is rated at 80 mA with a switching frequency of 5 kHz and a response time of 100 µs. The output current maximum is 200 mA and the analog output ranges from 0.15 V to 6 V. Circuit protection includes reverse polarity protection and output short-circuit protection. The IP67 enclosure rating ensures resistance to dust and water ingress.
Zinc Diecast Housing with Cable Connection
The housing measures 80 mm x 30.4 mm x 64 mm and is constructed from zinc diecast for durability. Light emission can be configured on the long or short side of the housing. Connection is via a 2 m cable with a male connector. A potentiometer allows for sensitivity adjustment and a 22 k OHM pull-up/pull-down resistor is integrated.

Questions about this item
How do I install the NT6-N112 sensor and what step is often missed?
Mount the rectangular zinc diecast housing using its 80 mm by 30.4 mm by 64 mm dimensions, connect the 2 m cable with male connector to a 10 V DC to 30 V DC supply, then set the potentiometer for the 9 mm sensing distance — the step often missed is verifying the ± 2 mm tolerance after power-up.
What maintenance or replacement will the NT6-N112 need later?
The IP67-rated housing and reverse-polarity-protected circuit require no scheduled maintenance; only the red/green LED light source at 560 nm or the NPN switching output may need replacement if the 200 mA output current limit is repeatedly exceeded.
What limit appears first during sustained operation of the NT6-N112?
At a 5 kHz switching frequency the 100 µs response time and 200 mA output current ceiling are reached before thermal limits, so continuous high-speed cycling will hit the current limit first.
