What type of sensor is this?

This unit is a photoelectric proximity sensor, often described as a photoelectric switch, designed to detect objects without physical contact. It uses background suppression and optical time-of-flight technology to provide reliable detection over a long adjustable sensing range.

What is the sensing range?

The sensor offers an adjustable sensing range from 100 mm up to 3,800 mm, with a maximum range stated from 50 mm to 3,800 mm depending on the target and application conditions.

Is this suitable for detecting objects in front of a background?

Yes. Its background suppression design helps it distinguish the target from objects or surfaces behind it. This makes it a strong choice for conveyor, handling and packaging duties where background objects could otherwise cause false switching.

What light source does the sensor use?

It uses a visible red laser light source with a wavelength of 658 nm. The device is rated as Laser Class 1.

How is the sensing distance adjusted?

Adjustment is carried out using a 4-turn potentiometer, and the housing also includes a single teach-in button. This gives the user a practical way to set the switching point for the application.

What supply voltage does it require?

The operating supply voltage is 10 V DC to 30 V DC. Current consumption is 70 mA without load at 24 V DC.

What output type does it provide?

This model provides push-pull outputs, allowing PNP or NPN integration. It has two switching outputs, Q and /Q, which are complementary and support light switching or dark switching.

What is the maximum output current?

The maximum output current is 100 mA. At ambient temperatures from 45 °C upwards, the permitted maximum load current is reduced to 50 mA.

How fast does the sensor respond?

The response time is 5 ms or less, with a switching frequency of 100 Hz. This makes it suitable for many general industrial detection tasks where quick object recognition is required.

What electrical connection does it use?

The sensor uses a 5-pin M12 male connector. This is a common industrial connection format and can simplify integration into existing machinery and sensor cabling layouts.

What environmental protection rating does it have?

It is rated IP67, which means it is built for industrial environments where protection against dust ingress and temporary exposure to water is important.

What are the operating temperature limits?

The operating ambient temperature range is -35 °C to +50 °C. The storage temperature range is -40 °C to +70 °C.

What are the physical dimensions of the unit?

The housing dimensions are 20 mm x 49.6 mm x 44.2 mm. The compact rectangular body can help where mounting space is limited.

What material is the housing made from?

The housing is made from VISTAL plastic, while the optics material is PMMA. This gives the sensor a lightweight but practical construction for industrial installation.

Can it be used for long-distance object detection?

Yes. This sensor is intended for relatively long-range detection for its class, reaching up to 3.8 metres. In the SICK range, the WTT12L-B2561 version is often chosen where a compact sensor is needed but standard short-range diffuse sensing is not enough.

Does the sensor include a complementary output?

Yes. It provides both Q and /Q outputs, giving complementary switching signals. This can be useful where the control system needs a normally-on and normally-off style signal arrangement from the same device.
