China-based supplier of magnetic sensors specializing in Tunneling Magnetoresistance (TMR) technology company, MultiDimension Technology Co. Ltd. (MDT) releases the TMR13DX pre-programmed TMR magnetic switch sensors at Sensors Converge 2021.
The new product allows factory-presetting of switching threshold parameters before delivery based on customer requests. TMR13DX offers performance consistency with enhanced adaptability for a variety of applications including utility meters, proximity switches, liquid level sensing, linear and rotary position sensing.
“The multi-function programmable sensor design of TMR13DX is suitable for various operating conditions of many magnetic sensor applications. Combined with MDT’s unique TMR sensor design, TMR13DX’s built-in signal conditioning circuitry and programmable logic unit can perform factory presetting of the on/off switching thresholds as well as the sensing polarity and output interface. It provides a universal solution that is readily available to meet new requirements from the market, without requiring customers to modify their designs, thus greatly accelerating their design cycle and time-to-market,” said Dr. Song Xue, Chairman and CEO of MultiDimension Technology. “In today’s semiconductor supply shortages, our ability to deliver this versatile and ready-to-use solution will promptly facilitate new customers who are looking for alternatives to short-supplied products on the market. Current MDT customers will also benefit from TMR13DX as a pin-to-pin compatible backup option to secure their supply during this difficult time.”
TMR13DX is available in the following default configurations, with options to factory-preset alternative switching points, different polarities (omnipolar, bipolar, or unipolar), and customizable output interface (open-drain or push-pull, active-high or active-low).
