OHN3120U

The OHN3120U is a Hall Effect Device containing a monolithic integrated circuit which incorporates a hall element, a linear amplifier, a threshold amplifier and Schmitt trigger on a single Hallogic® silicon chip. Included on-chip is a band gap voltage regulator to allow operation with a wide range of supply voltages. These devices feature logic level output and provide up to 21mA of sink current. This allows direct driving of more than 7 TTL loads or any standard logic family. Output amplitude is constant at switching frequencies from DC to over 200kHz. The Uni-Polar turns on with a (logic level "0") after a sufficient magnetic field from the south pole of a magnet approached the symbolized face of the device (Operating Point) and turns off (logic level "1") after the magnetic field reached a minimum value.

• Designed for non-contact switching operations
• Operates with excellent temperature stability in harsh environments
• Drive capability up to 7 TTL loads
