WTB4FT-21311120ZZZ, SICK, diffuse photoelectric sensor with background suppression, optical sensor, 1113176

WTB4FT-21311120ZZZ, SICK, diffuse photoelectric sensor with background suppression, 7 ... 120 mm, Protitakt: PNP/NPN, 10 V DC ... 30 V DC

WTB4FT-21311120ZZZ is a diffuse photoelectric sensor with background suppression made by SICK. This type evaluates the object within the set sensing area and limits the influence of the more distant background behind the monitored object. This variant combines a sensing distance of 7 ... 120 mm, output Push-pull: PNP/NPN, supply 10 V DC ... 30 V DC and connection Connector M8, 3-pin.

Typical applications

Model WTB4FT-21311120ZZZ is designed for detecting objects in front of a machine structure, conveyor or other fixed background, especially where more stable discrimination of the target from the background is needed. When designing the application, it is advisable to verify the actual working distance, target properties, mounting space and ambient conditions.

Technical specifications

Wiring and integration into the control system

Model WTB4FT-21311120ZZZ wire according to the technical data of this specific variant. Before integration into a PLC or control system, check in particular the supply 10 V DC ... 30 V DC; output type Push-pull: PNP/NPN; connection Connector M8, 3-pin. For versions with PNP/NPN selection, set the output logic according to the PLC input used.

Application example – detecting a part in front of a fixed background

The sensor is set so that it reliably evaluates the product at the working distance but does not respond to a more distant part of the machine or conveyor. This is useful, for example, when checking the presence of parts of different colours in front of a constant background.

Why choose this variant

Model WTB4FT-21311120ZZZ is a specific variant of the type diffuse photoelectric sensor with background suppression with a combination of parameters 7 ... 120 mm · Protitakt: PNP/NPN · 10 V DC ... 30 V DC · Connector M8, 3-pin · IP66 (EN 60529), IP67 (EN 60529). This configuration makes it easier to match the sensor precisely to a specific task and the electrical interface of the machine.
