OH34 Unipolar Hall Effect Switch IC

General Description:
Part No.: OH34 Operate temperature: -40～125℃ Package:3000pcs/reel

OH34 Hall switch IC is internally consisted by reverse voltage protection device, voltage regulator, hall voltage generator, a differential amplifier, Schmitt trigger and the open collector output level, which can change magnetic field signal into digital voltage output. With the typical feature of small size and stable performance, OH34 is widely used in all kinds of position control, speed detection, flow detection occasions as a non-contact switch.

Precautions of OH Series Hall ICS
Hall ICs are sensitive devices which performance could be influenced in some extent by magnetic, optical, thermal and mechanical stress.
1) A pull-up resistor RL should be connected between the power supply (Vcc) and the output (Vout) since most of hall ICs are open collector output (OC output) circuits, such as OH44E, OH137, OH513, OH543. Hall ICs with Build-in Resistor are not necessary to add one, for example OH921.
2) Avoid reversing the power supply (Vcc) and the output (Vout) as well as no overload use. Be careful of the burn and damage caused by instant large current and instantaneous high voltage.
3) The Protection circuit should be added in the test circuits of hall ICs, such as large capacitor and a voltage stabilizing diode, which could absorb the effects of the external circuit and power fluctuation.
4) Try to minimize the mechanical stress applied to the device and leads during the installation, especially on the pins where close to the root of the device when bending shaping etc.
5) Strictly regulate the welding temperature and time. When manual welding, the temperature of soldering iron shall not exceed 260℃and time should be less than 3 seconds.
6) When designing, please fully consider the influence factors of temperature, magnetic field attenuation, the movement way, etc.
