Cost-effective bipolar Hall-effect sensors in the SS50AT series in an SMD-equippable housing have a thermally balanced integrated circuit over the entire temperature range. The bipolar magnets respond to alternating north and south poles. An integrated regulator ensures stable operation at a supply voltage of 4.5-24 VDC, and an internal circuit prevents damage to the sensor if the polarity of the supply voltage has been inadvertently reversed. The cost-effective bipolar Hall-effect sensors in the SS50AT series are small and versatile digital Hall-effect devices that are driven by the magnetic field of a permanent magnet or an electromagnet. The voltage of the P-switching power output of the open collector can be easily connected with a large selection of electronic circuits. - Miniature construction: SOT-89B plastic housing in belt packaging for automatic insertion - Max. power consumption of 5 mA at 4.5 V DC for energy efficiency - Digital P-switching power output - Bipolar magnets for ring-magnet applications - High output rating (20 mA) - High speed - operating speed of 0 kHz to more than 100 kHz - Large temperature range from -40°C to 125°C (-40°F to 257°F) - Integrated reverse-polarity protection Technical product data: Product type: Integrated circuit for digital Hall-effect position sensors Package type: SOT-89B Supply voltage: 3.8-30.0 V DC Output type: Sink Connection type: Surface-mounted installation Magnetic actuator: Unipolar Operating temperature: -40°C to +150°C Output voltage: 0.4 V DC max.
