| Item Description | The TMR6218 magnetic pattern recognition sensor consists of tunneling magnetoresistance (TMR) sensing elements, a high-quality magnet, a robust plastic base with outstanding mechanical strength, and a durable non-magnetic stainless steel cover. The TMR6218 series of TMR magnetic pattern recognition sensor is a magnetic signal reader head for use in detecting and recognizing the magnetic properties of paper bills, bank notes, and securities documents. Designed with outstanding weak field detection capability of mul's TMR technology, along with a customized hollow-shaped bias magnet, the TMR6218 features high sensitivity, high signal to noise ratio, and wide air-gap tolerance, and it is not susceptible to tilt or misalignment in installation or shock and vibration along the vertical direction (z-axis) during operation.the TMR6218 sensor series applies high mechanical strength plastic, and |
