In 1984 our R3 148 KHz product line debuted. These products are still supported today! In the late 1990’s the RFID industry began to gravitate toward 125 KHz as a standard for electronic components within our industry thus our R3-1 125 KHz product line began to take shape in 1998. By 2002 we had learned a few things and introduced a more advanced networkable product line, or what we call R3-2 125 KHz, and is today our premier LF (low frequency) product offering. New users and projects in the LF realm should look only to this line given it’s advancements and broader hardware offering. These 3 products are not interchangeable.

Current users, if you are not sure which frequency you have installed please refer to a product manual, cross reference the part number (Assy Number) on the part to a price list or product brochure, or contact us via our contact page
