Overview
Phares Electronics Digital Output Hall Effect Sensors are simple on/off non-contact switching devices. Digital output signal is clean,
fast and switched without bounce – an inherent problem with mechanical contact switches. They are magnetically activated switches
that detect the motion, position, or change in field strength of an electromagnet, a permanent magnet, or a ferromagnetic material with
an applied magnetic bias. The digital output is a square-wave signal that is directly proportional to the input (linear). The digital
output signal is ideal for logic inputs (PLC/DCS) and other devices that can measure frequency directly. This includes our Tachometers and Remote Zero Speed Switch. A pull up resistor may or may not be needed depending on the logic input or device.
Our Hall Effect Sensors are compatible with all digital families. They provide reliable, repetitive operation in close tolerance
applications. They are more efficient and effective than inductive or optoelectronic sensors as they are virtually immune to
environmental contaminants and are suitable for use under severe service conditions. Our Hall Effect Sensors can see precisely through
dirt and darkness.
Description
The Phares Electronics Digital Output Hall Effect Sensor switches logic low ("0") when the magnetic field strength at the
sensor face exceeds the hall effect operate point threshold, and switches logic high ("1") when the magnetic field strength
falls below release point threshold. The difference in the magnetic operate and release points is the hysteresis of the Hall Effect
Sensor. This built-in hysteresis allows clean, fast switching of the output, even in the presence of external mechanical vibration and
electrical noise. The omnipolar operation allows activation with either a north or a south polarity field of sufficient strength.
In the absence of a magnetic field, the output is off.
Installation
The Phares Electronics Digital Output Hall Effect Sensor can be secured via ½" conduit fitting, bracket, or both depending
on sensor housing length. Various sensor housing lengths allow greater flexibility regarding mounting and bracket location. Use our
Terminal Strip Assembly (TSA) Box for quick mounting and termination, and applications that require long cable runs. When using a bracket
do not over tighten jam nuts. If vibration is an issue, use removable thread lock to keep jam nuts secure.
