GP20 Proximity Reader

The GP20 Reader is a very compact Reader using contactless Passive Transponder Cards offering long reading distances (max. 20 cm) despite its’ compact dimensions. It is fully potted and therefore particularly suitable for indoor and outdoor use like access control, parking and Time & Attendance. It is suitable for a wide range of applications due to its’ variable operating voltage (5 – 13.5 Volts DC) and the user-selectable output formats.
