Banner Engineering SLE5 High Speed Optical Label Sensors

The SLE5 from Banner Engineering is a rugged, industrial label detection sensor. Its high performance, fast switching frequency and compact housing are ideal for labelling machines. The SLE5 can detect single layer as well as multi-layer booklet labels, such as coupons or instructions commonly used in food, beverage and pharmaceutical applications. Single button teach easily establishes the threshold between the backing paper and label, ensuring that product waste is minimized during set-up.

Key Benefits

High Performance – The small infrared light spot of the SLE5 can quickly detect the gap between opaque labels on clear or opaque backing. The 5mm slot width and 50mm slot depth allow precise detection of a wide variety of products, including multi-layer booklet labels. The SLE5 can detect as small as a 0.5mm minimum label or gap width. 40µs response speed (12.5 kHz switching frequency) for increased position accuracy assures precise detection and placement on fast moving production lines.

Easy to Use – The SLE5 can be taught via single teach button or remote teach wire and can be configured to detect the label or the backing paper based on teach order. Teach mode can be performed either statically or dynamically at speeds up to 20 meters per minute. Highly visible green and amber status LEDs confirm teach was accepted and current output status.

Simple Installation – The SLE5’s compact housing features make it easy to install in the dispensing ledge. The dovetail mounting option is designed for simple installation directly on machines, no tools required. Standard M5 mounting holes are also available for maximum versatility. Models are available with 2m cables or integral M8 connector and with NPN or PNP output.
