Lable sensor improves reliability and requires no user adjustments

April 2000 Sensors & Transducers

RET Automation now offers Banner Engineering's SLC1 Series label sensor, a high-precision label sensing device that requires no programming or adjustments. Designed to provide accurate detection of labels on web backing, the SLC1 reliably senses the difference between extremely low contrast materials, including clear labels on opaque or clear backing and opaque labels on opaque or clear backing. The SLC1 is a good solution for label-registering applications and label-counting tasks in slitting or rewinding applications.

The SLC1's patent-pending adaptive digital logic (ADL) system enables its high-resolution microprocessor to 'learn' label characteristics, in just 250 ms or the passing of four labels, and provide continuous automatic adjustment of sensing threshold and drift compensation for maximum sensing precision. Users simply place the label web in the sensing slot location marked 'sensing area' and allow the labels to run through the sensor.

The label sensor has a maximum label counting speed of 40 000 labels per minute; web speed of 3660 m per minute. The minimum sensing speed is one label per minute; web speed of 90 mm per minute. It provides a typical registration accuracy of ±0,3 mm at speeds up to 1000 labels per minute.

Green and yellow LEDs indicate Power on and Output on status and flash to alert the user of overloaded output or incorrect detection.

Integral circuitry protects the sensor against reverse polarity, transient voltages, overload, shorted load and low voltage. The output configuration is bipolar, one sourcing (PNP) and one sinking (NPN) open collector transistor. Each output is capable of switching up to 150 mA.

This compact, self-contained, 10 to 350 V d.c. sensor features a heavy-duty machined aluminium housing, with a 1 mm slot and black anodised finish. It has environmental ratings of IP67 and NEMA 6 and operates reliably in temperatures of 5–50°C. The SLC1 is available with a 2 or 9 m attached cable, or an integral five-pin Euro-style quick disconnect fitting.
