The SS443A is a temperature compensated digital hall effect sensor IC in 3 pin TO-92 package. This small, versatile digital hall effect device is operated by magnetic field from permanent magnet or an electromagnet. It is designed to respond to alternating north and south poles or to south pole only. Band gap regulation provides stable operation over 3.8VDC to 30VDC supply voltage range. The SS443A is capable of continuous 20mA sinking output and may be cycled as high as 50mA maximum. Its 3.8V capability allows for use in many potential low voltage applications. The digital, open collector sinking type output is easily interfaced with wide variety of electronic circuits.
- Unipolar magnetics, medium gauss operating characteristics
- Straight leads, 14.99mm long and 1.30mm spacing
- Quad hall IC design minimizes mechanical stress effects
- Temperature compensated magnetics helps provide stable operation over a wide temperature range
- Automated component placement and potentially reduces installation costs
- Broad supply voltage capability from 3.8VDC to 30VDC for application flexibility
- Digital, open collector sink output for easy interfacing with variety of common electronic circuits
- Operating temperature range from -40°C to 150°C (-40°F to 302°F)
Applications
Sensing & Instrumentation, Medical, Industrial, Robotics, Motor Drive & Control

It works, quality could be better
I was going to use this on a trip from Boise to Alaska as a multi use radio to listen to LADD, FRS, GMRS, and talk on Ham frequencies. After programming it and playing around with it, I decided to take my FT7250D.
Like:
Small size
Lots of memories
Audio is OK
Programming cable included.
Multi frequency monitoring, if you’re into that (I’m not).
Dislike:
Quality - knobs are soft rubber and come off easily.
4 frequency displays. Why? Cannot turn them off.
Display text is small because of the 4 displays.
Accessing features and menu items can be confusing.

Tight Top Loaders
Size: 200 Hard Sleeves+200 Soft Sleeves
Fine cases, just a little tight trying to put cards in. Seller acknowledged and gave his advice to alleviate the matter. And offered a partial refund for the trouble. Very much appreciated, this is a great seller and will order from them again.
