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.

Found the component i was looking for ad a great price. Great support from the staff as I was paying using a wire transfer. - Quick delivery and very good packaging.Adriano Tiberi
Extremely Helpful. Shipped me a replacement unit next day and i was up and running within 24 hours. Replacement new from machinery manufacturers was on a 7 day lead time.Sean Conlin
Found the part we needed at the best price. Spoke to Rob to make sure the part was actually in stock, as many companies don't actually have the part available to ship. It was in stock ready and the part was checked and shipped and received within a couple of days from their German stock. Would definitely use again and recommend.Chris Sentance
FIRST TIME WORKING WITH MARVO. THEY HAD WHAT I NEEDED AND TOOK GREAT CARE OF ME AND GOT MY ORDER OUT IMMEDITELY. WAS VERY IMPRESSED WITH THE SERVICE AND THE PERSON I SPOKE WITH. I WILL DEFINITELY WORK WITH THEM QGAIN IN THE FUTURE.Robert Cohen
