Overview

Versatility for standard applications

The WLL170-2 fiber-optic photoelectric sensor family features a standard operating system that is especially suitable for basic applications, but can be used when rapid response times are crucial. There are several variants. The WLL170(T) version is optimized for a number of key applications, such as detection of very small objects, colored marks, or transparent objects. The WLL170T-2 is a teach-in version where the switching threshold can be set either automatically by pressing a button or via a cable. In contrast, the WLL170-2 has a manual switching threshold adjustment via a potentiometer. Both models are available in a high-speed version with a switching frequency of 10 kHz for extremely fast response times. For optimum detection of color contrasts, you can choose between devices with a red or green LED emitter. Detection tasks are handled securely and reliably using the LL3 series of fiber-optic cables.
