3 GENERAL DESCRIPTION
HITAG(1) is the name of one of the universal and powerful product lines of our 125 kHz family. The contactless proximity read and write system that works with passive transponders is suitable for various applications. Inductive coupling helps you to achieve reading ranges up to
200 mm and the use of cryptography guarantees highest data security.
The HTRM440 provides you with a universal, cost-effective, small and complete reader module. It enables communication with the 125 kHz transponders HITAG 1 and HITAG 2.
Easy integration and application of the HTRM440 is due to small size and uncomplicated interfaces.
