Overview
Hallogic Hall Effect Sensor Assembly OHB900 Features: • Non-contact motion sensing • Operates over a broad range of supply voltages • Excellent temperature stability • Hall element, linear amplifier, and Schmitt trigger on a single Hallogic silicon chip • Performs in high dust and dirt environments over a wide temperature range • 0.
125” (3.
18mm) wide gap Description: The OHB900 consists of a Hall Effect sensor similar to the OH180U 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, reducing the magnetic flux density at the Hall Effect sensor location, the open collector output transistor switches off.
The device provides up to 25 mA of sink current.
Output characteristics are constant at switching frequencies from DC to over 200 kHz.
The Uni-Polar turns on ...
