WL-OSEN – the compact infrared sensors – are the founding members of a new product group: optical sensors from Würth Elektronik. The particularly compact version measures just 2.0 × 1.6 × 0.75 mm. — Image source: Würth Elektronik
Würth Elektronik launches a new program for optical sensors (product code: WL-OSEN) with the first two components. These compact modules contain both emitters and detectors for infrared light at 940 nm wavelength. A special feature: The Würth Elektronik sensors filter out visible light up to 800 nm, rather than just up to 700 nm as is the case for many other sensors of this type available on the market. So they are less susceptible to errors occurring under artificial lighting.
The sensor in the 4-SMD gullwing standard housing measures 2.7 × 3.4 × 1.5 mm without contacts. It is designed for close range, typically at a distance of 1 mm and serves as a simple touch switch, for example under a glass plate.

The second compact SMD sensor, with its lower beam angle and measuring 2.0 × 1.6 × 0.75 mm, can detect at a greater distance up to 10 mm, making it more robust against crosstalk than a simple touch switch, e.g., when used under glass. Both sensors offer an analog output and low energy consumption. Possible applications include optical encoders, switches and interlocks, as well as object detection or touch applications.
The Würth Elektronik infrared sensors are now available from stock without a minimum order quantity. Developers can receive free samples.
