Mühlbauer’s inlay test handler ITH 540 is a semi-automatic machine for the testing of transponders integrated in sheets. The system is well-proven, easy-to-operate and offers the possibility to freely program different sheet layouts. The processes of testing and pre-personalization of RFID pre-laminated sheets, collated sheets, laminated sheets and inlay sheets have significantly been simplified. The integrated ETS-surface for ergonomic operations guarantees convenient functionality for operators. The easy-to-maintain construction with a prolonged lifetime reduces running costs. The IT 50 inlay tester is used to manually check the functionality of the transponders which are integrated into sheets. The simple device offers highest flexibility as it can be transported to any location and allows an operator to quickly determine if the antenna is defect. Two LEDs indicate the test results: green indicates a functional antenna, whereas red indicates a defect. Damaged antennas are then marked to ensure that all antennas used in production are fully functional.
