MS120 Pen Scanner (Stainless Steel Wand) The MS120 Series Barcode Wands are targeted toward low reading volume and cost effective solutions. The advanced optics and electronic design convert barcode labels into a high quality digital signal. Able to read color, faded and low contrast barcodes quickly and accurately, the MS120 is a proven solution. The polished sapphire tip reduces wear on labels and is also easily replaced if damaged. The MS120 is available with three different interfaces. The MS120 A is an undecoded model which interfaces via a 9-Pin squeeze release connector. The MS120 -2 has an RS232 interface with a built-in decoder. With a key-board wedge (AT or PS/2) interface the MS120 -3 also has a built-in decoder. It's shape gives the MS120 the comfort and handling of a normal ink pen. Just sweep the tip of the wand across the barcode in either direction and listen for the good read beep that lets you know the data has been successfully captured. It doesn't get any easier than that.
