Large Format Printer (SSIN-01)
The Challenge

The OEM customer needed a flexible and cost effective encoder solution for a line of high quality large format printers. The customer had been having quality issues with inconsistent performance from a competitor’s glass scales, and was looking for a more convenient metal tape scale solution for the required travels up to 4500mm.

The Solution

MicroE paired a standard configuration compact Mercury II series digital output sensor with 1µm resolution along with Marker Tape featuring an index every 50mm.  The multi-index Marker Tape can be supplied in dispenser of lengths up to 30 meters long (or cut to a specific length), making it ideal for OEMs that produce axes of various lengths.

The Benefit

The selected Mercury II sensor is a standard product, minimizing cost and lead time. The application calls for various long lengths of tape scale, and the ability to purchase up to 30 meters of tape on a reel allows the customer to stock just one scale part number. With indexes every 50mm, the customer can cut scales to length and have the index placed where needed.
