TT Electronics OHB900 Hallogic Hall-Effect Sensor detects non-contact motion with a Hall-effect principle, operating within a supply voltage range of 4.5V to 25V and over a wide temperature range. These sensors integrate a hall element, linear amplifier, and Schmitt trigger in one chip, housed with a rare earth magnet in a plastic casing. The sensor has an open collector output that activates when the slot is open and deactivates when blocked by ferrous material. These sensors support up to 25mA of sink current and function reliably at switching frequencies from DC to over 200kHz, making them suitable for non-contact switching applications.
