Description
:
The OHB3040 consists of a ceramic Hall-effect sensor (OMH3040) and a rare earth magnet mounted in a low-cost plastic housing. The magnet produces optimum magnetic flux at the Hall-effect sensor location. The sensor has an open collector transistor output, which is activated when the slot is open. When the slot is blocked by a ferrous material that reduces the magnetic flux density at the Hall-effect sensor location, the open collector output transistor switches off. The device provides up to 25 m A of sink current. Output characteristics are constant at switching frequencies from DC to over 200 k Hz. The OHB3040S has...
