QS30ELVC Series high-performance retroreflective sensor with a 5-pin Euro-Style QD:

The Banner QS30ELVC series is an easy-to-use, high-performance retroreflective sensor optimized for detection of clear, translucent, or opaque objects. The optical design of the sensor ensures reliable detection of PET bottles, glass containers, and optically engineered surfaces such as mirrors, LCD glass with polarizing films, or semi-conductor wafers. The sensor will not be tricked by specular reflections from the object under normal operating conditions.

The compact housing has a large, easy-to-see bargraph display for easy configuration and status monitoring during operation. The sensor housing can be side-mounted, using integral mounting holes, or front-mounted, via the 30 mm threaded barrel. A wide assortment of mounting brackets are also available for applications requiring adjustability or robust mechanical protection.

The QS30ELVC is simply aligned to the included retroreflective target and the Light SET procedure is initiated either via the push button or the remote wire input. A reliable detection is assured when the appropriate threshold for clear, translucent or dark object is selected.

Continued reliable operation is maintained as the thresholds adapt to changing signal levels over time using Banner Engineering’s auto compensation tracking algorithm. The sensor tracks the amount of light returned at every opportunity and makes fine adjustments to the switching threshold as required due to dust or contamination in the environment building up on the lens window or reflector. If the retroreflector is cleaned, returning the light to its original level, the sensor quickly adapts and continues operating with no need to perform another Light SET procedure.

The sensor can recover from a cold power-up by re-using the stored threshold values from the last Light SET procedure. You only need to perform the Light SET procedure if the sensor is moved or the sensor to reflector separation distance is changed.

The sensor ships from the factory as a DARK OPERATE (DO), non-polarized retroreflective sensor with auto compensation enabled for easy set-up and reliable operation. The automatic compensation tracking algorithm can be disabled if required through the user SETUP buttons or the remote teach wire.
