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
