VF526DT

SS520 Series Hall-effect digital position sensor IC with speed and direction outputs, dual latching, SOT-89B, 1000 units/pocket tape and reel.
The VF526DT Bipolar Latch, Dual Hall-effect Digital Position Sensor has two distinct Hall sensing elements precisely located 1,4 mm [0.055 in] apart on a single integrated circuit chip. The elements are encapsulated in a thermoset molding material. The two active Hall latches provide speed and direction indication of a magnetic gradient (such as a rotating ring magnet) across the face of the package. The miniature, 4-pin SOT-89B package surface mounts on PC (Printed Circuit) boards and flexible circuits. The VF526DT’s built-in temperature compensation is designed to match the temperature coefficient of low-cost magnets, allowing for a reliable, yet cost-effective, sensor-magnet combination. A unique, regulator circuit provides extremely stable operation with supply voltages from 3.4 Vdc to 24 Vdc. It can directly interface with many electronic components without buffering or compensation circuitry.

A built-in regulator provides very stable operation over 4.5 Vdc to 24 Vdc supply voltage range, and internal circuitry prevents sensor damage in case the supply voltage polarity is accidentally reversed. The SS50AT Series Low-Cost Bipolar Hall-Effect sensors are small, versatile digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet. The open-collector sinking output voltage is easily interfaced with a wide variety of electronic circuits.

NOTE: The integrated circuitry provides excellent temperature stability and accuracy in a robust design. These digital Hall sensors have an operating temperature range of -40 °C to 125 °C [-40 °F to 257 °F], appropriate for commercial, consumer, and industrial environments.
