Miniature photoelectric sensor

The Sick WTB4-3N1361S16 is a rectangular photoelectric proximity sensor that uses visible red PinPoint LED light and background suppression to detect small objects. It operates on 10 V DC to 30 V DC and provides an NPN light-switching output with a maximum load of 100 mA. The housing measures 16 mm by 39.5 mm by 12 mm and carries IP66 and IP67 enclosure ratings.

Suited for DC-supplied automation needing precise

This sensor suits machine builders and electricians who require a compact background-suppression device for 15 mm to 150 mm sensing on a 10 V DC to 30 V DC supply. It is not for applications that need AC supply voltages, PNP switching outputs, or detection ranges beyond 150 mm.

150 mm maximum sensing range with 2 m PVC cable

The decisive specification is the 150 mm maximum sensing range combined with a fixed 2 m, 3-wire PVC cable. This range and cable length determine whether the unit fits the mounting distance and wiring layout of the intended installation.

Questions about this item

How can I verify the WTB4-3N1361S16 is operating correctly after wiring it to a 10 V DC ... 30 V DC supply?

With power applied, the visible red PinPoint LED projects a Ø 7 mm spot at 50 mm; place a target within the 15 mm ... 150 mm sensing range and the NPN output should switch within < 0.5 ms at up to 1,000 Hz.

What does the box contain for the WTB4-3N1361S16 and what must I source separately?

The box includes one sensor with a 2 m PVC cable (3-wire, 0.14 mm², Ø 3.4 mm) and a mounting bracket; you must supply a 10 V DC ... 30 V DC power source and any mating connector or terminal blocks.

Which sensing-range version of the WTB4-3N1361S16 should I choose for detecting small objects at close distance?

This model offers a fixed 15 mm ... 150 mm range with background suppression and a Ø 7 mm light spot at 50 mm, making it suited for small-object detection at short distances.
