00:00Okay, so if you've ever tried building a brushless motor controller, a DIY tachometer, or even just a simple magnetic
00:06door switch, you know the whole project lives or dies on one tiny little part, the Hall Effect Sensor.
00:11And honestly, the prices on these things are all over the place.
00:15So I went digging and found the 5 best deals out there right now on Hall Effect Sensor ICs for
00:20motors.
00:22Let's get into it.
00:23First up, and this one genuinely made me do a double-take, it's a multi-pack of 44E and 49E
00:29Surface Mount Hall Sensors, and you're looking at SS49E, H49E, and a 3144E options in that tiny SOTY23 package.
00:38The big deal here is the price, 23 cents.
00:41Not a typo.
00:4423 cents.
00:45Now obviously that's for the smaller pack tier, but even so, this is the cheapest entry point on the list
00:51by a mile.
00:52Over 4,500 sold with a perfect 5-star rating, and if you're doing SMD work on compact motor driver
00:58boards, that SOTY23 footprint is exactly what you want.
01:02Buy a handful, blow a few up learning, who cares at this price.
01:07Number 2 is my pick if you're not sure what you actually need yet.
01:10This is a 10-piece lot, but the seller stock's basically the whole family 44E, 49E, 41F, 3144E, US1881, AH3503,
01:21OH137.
01:23That's linear sensors, latching sensors, and switching sensors all in one place.
01:28So you can grab a strip of latching US1881S for a BLDC commutation project and analog AH3503S for current sensing
01:36from the same order.
01:38$1.47, 5 stars, over 4,200 sold.
01:43Having options matters more than people think when you're prototyping.
01:47Third on the list, and this is the bulk buy.
01:50A hundred pieces of A3144, OYS3144, or Y3144 in the 292UA through-hole package for $6.05.
02:00Do the math on that, you're paying about $0.06 per sensor.
02:05The A3144 is the Workhorse Omnipolar Switching Hall Sensor, it's the one you see in almost every hobby BLDC build,
02:11every RPM counter, every DIY encoder wheel.
02:15If you're a makerspace, a classroom, or you're building something that needs dozens of these, this is the one.
02:21Nearly 3,500 sold, perfect rating.
02:24Number 4 is the Balanced Middle Ground Option, a 10-pack that mixes 49E, 44E, 41F, and a 3144 or
02:32Y3144 in classic 292.
02:35For 53, 4.9 stars, over 3,000 sold.
02:40Why pick this over the Big 100 pack?
02:43Simple.
02:44You get variety instead of volume.
02:47The 49E gives you a linear analog output that's great for measuring magnetic field strength or building a contactless throttle.
02:54While the A3144 handles clean digital switching.
02:57If you're a hobbyist working on one or two projects, 10 mixed sensors is way more useful than a hundred
03:02identical ones sitting in a drawer.
03:05I'm rounding out the list at number 5, 10 pieces of OH3144, A3144, or Y3144 in 292UA for $0.47.
03:15That's under $0.05 a chip, in a small pack, with no bulk commitment.
03:20It's from Lovcat, which a lot of you will recognize from other cheap component orders, and it's marked in stock
03:25which honestly is half the battle.
03:284.8 stars, almost 2,900 sold.
03:32This is the just throw it in the cart purchase, you don't need them today, but the day your motor
03:36project needs a rotor position sensor, you'll be very glad they're in the parts bin.
03:41All 5 of these are linked down in the description, so go grab whichever one fits your build.

03:52Thanks for watching, and I'll catch you in the next one.
