Sensing and Control Ratiometric Linear Hall-Effect Sensor OHS3150U, OHS3151U Features: Ra�ometric linear output capable of sinking and sourcing current 4.5 V to 6.0 V opera�on Responds equally to posi�ve and nega�ve magne�c Ţelds Excellent temperature stability to operate in harsh environments Robust package capable of withstanding harsh environments Descrip�on: Each ratiometric linear Hall-effect sensor contains a monolithic integrated circuit on a single chip. This circuit incorporates a quadratic Hall sensing element, which minimizes the effects of mechanical and thermal stress on the Hall element and temperature compensating circuitry to compensate for the inherent Hall element sensitivity change over temperature current. These ratiometric linear Hall-effect sensors provide an output voltage that varies in proportion to the applied magnetic field. The voltage output will increase in response to a south pole (positive) magnetic field applied perpendicular to the package symbolization face, and will decrease in response to a north pole (negative) magnetic field. These ratiometric linear Hall-effect sensors can be used as a non-contact sensor for rotary and linear position sensing and for current sensing. Ordering Information Applica�ons: Through Hole Temp.

The change in quiescent voltage output over temperature gives the device’s equivalent accuracy and is speciŢed in gauss by the calcula�on. V ‐ V OQ (TA) OQ (25°C) ΔV = ————————‐ OQ (T) Sens (25°C) Sensi�vity: A magne�c south pole at, and perpendicular to, the device’s symbolized package face will increase the voltage output above the quiescent value. Conversely a magne�c north pole will decrease the voltage output below the quiescent value. This change in voltage output with applied magne�c Ţeld is sensi�vity and is speciŢed in mV/G by the calcula�on.

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
