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.

We know where to find the rare and obsolete equipment that our customers need in order to get back to business. We stand apart from our competition through our commitment to quality, and look forward to the opportunity to show you how.

Is there a warranty for the OHS3150U?

chervon down
The warranty we offer will be based on what we negotiate with our suppliers. Sometimes, a part will be sold as-is and without a warranty. We usually offer a one-year warranty for single board computers in particular because they are our specialty.

Which carrier will Electronics Finder use to ship my parts?

chervon down
We use FedEx, UPS, DHL, and USPS. We have accounts with each of them and generally ship using one of those, but we can also ship using your account if you would prefer. We are able to ship with other carriers if you would find it more convenient.

Can I buy parts from Electronics Finder if I am outside the USA?

chervon down
Electronics Finder will definitely serve you. We work with international clients all the time, which means we are regularly shipping goods all across the globe.

Which payment methods does Electronics Finder accept?

chervon down
Visa, MasterCard, Discover, and American Express are all accepted by Electronics Finder. We will also accept payment made with wire transfer or PayPal. Checks will only be accepted from customers in the USA. Terms may be offered (upon approval) for larger orders.

What they say about us

FANTASTIC RESOURCE

star star star star star

One of our top priorities is maintaining our business with precision, and we are constantly looking for affiliates that can help us achieve our goal. With the aid of GID Industrial, our obsolete product management has never been more efficient. They have been a great resource to our company, and have quickly become a go-to supplier on our list!

EXCELLENT SERVICE

star star star star star

With our strict fundamentals and high expectations, we were surprised when we came across GID Industrial and their competitive pricing. When we approached them with our issue, they were incredibly confident in being able to provide us with a seamless solution at the best price for us. GID Industrial quickly understood our needs and provided us with excellent service, as well as fully tested product to ensure what we received would be the right fit for our company.

HARD TO FIND A BETTER PROVIDER

star star star star star

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.

CONSISTENTLY DELIVERS QUALITY SOLUTIONS

star star star star star

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

star star star star star

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

star star star star star

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.
