The Sick WT34-R220 is a versatile and robust photoelectric sensor designed to meet the diverse needs of industrial automation. This compact sensor is engineered to provide reliable detection and measurement, ensuring precision in a variety of applications. With a rectangular housing measuring 27 mm x 92 mm x 70 mm, it is suitable for space-constrained environments.

The WT34-R220 operates on the principle of object reflection with background suppression, which allows it to accurately identify objects within a range of 100 mm to 2,500 mm. It utilises infrared light as its light source, with an LED that boasts an average lifespan of 100,000 hours at an ambient temperature of +25 °C, highlighting its longevity and reliability.

This sensor features a potentiometer for easy adjustment and customisation to specific application requirements. It is equipped with a relay output that is galvanically isolated, providing flexibility with a selectable light/dark switching function. The switching output can handle a current of up to 4 A at 250 V AC or 24 V DC, and 0.125 A at 250 V DC, making it suitable for a wide range of load conditions.

Constructed with a durable ABS plastic housing, the WT34-R220 is rated IP67, ensuring protection against dust and water ingress, which allows it to operate effectively in harsh industrial environments. It can withstand operating temperatures ranging from –40 °C to +60 °C and storage temperatures from –40 °C to +75 °C.

The WT34-R220 is a reliable choice for those seeking a high-quality photoelectric sensor that combines functionality, durability, and ease of use for efficient industrial automation processes.
