LTJ 系列磁性識別傳感器

LDJ-CM-T12-DS

?LDJ-CM-T12-DS is a high-resolution thickness detection module, which is usually being used to detect the thickness of bank notes and the tape on the bank notes. The principle is to detect the movement of permanent magnets caused by bank note’s passing through. TMR-based magnetic sensor enables the high accuracy and high signal-to-noise ratio.
