OPTEK TECHNOLOGY OHS3020U Hall Effect Sensor, Unipolar, 21 mA, SIP, 3 Pins, 4.5 V, 24 VThe OHS3020U is a Hallogic Hall effect Sensor contains a monolithic integrated circuit which incorporates a Hall element, a linear amplifier, a threshold amplifier and Schmitt trigger on a single Hallogic silicon chip. Included on chip is a band gap voltage regulator to allow operation with a wide range of supply voltages. These devices feature logic level output and provide up to 21mA of sink current. This allows direct driving of more than 7 TTL
The OHS3020U is a Hallogic Hall-effect Sensor contains a monolithic integrated circuit which incorporates a Hall element, a linear amplifier, a threshold amplifier and Schmitt trigger on a single Hallogic� silicon chip. Included on-chip is a band gap voltage regulator to allow operation with a wide range of supply voltages. These devices feature logic level output and provide up to 21mA of sink current. This allows direct driving of more than 7 TTL loads or any standard logic family using power supplies ranging from 4.5 to 24V. Output amplitude is constant at switching frequencies from DC to over 200kHz. The Uni-polar turns on with a (logic level "0") after a sufficient magnetic field from the south pole of a magnet approached the symbolized face of the device (operating point) and turns off (logic level "1") after the magnetic field reached a minimum value.
- Designed for non-contact switching operations
- Operates over broad range of supply voltages
- Operates with excellent temperature stability in harsh environments

This is an awesome product and affordably priced! I'll buy more in the future!
Color: Comet - Small, Size: Small
This is a great ball for my dog Polly! It doesn't stink or have any weird oils on the ball. It is definitely durable. It has a nice chirping sound and it's great exercise for my dog's jaws. It's not too bouncy and it's the perfect weight that she feels satisfied having in her mouth and when she catches it in mid-air. It's not too heavy that I have to worry about it knocking her teeth out. I almost cancelled the order after I found out the size of the ball, I thought it was a larger ball that Bark makes. It turns out it is larger than a tennis ball which is what I wanted. Someone gave us a black, knobby, ball that is 12.5 inches in diameter and she absolutely loves it, it's her favorite ball. It's the perfect size for her American Pit Bull mouth! I cannot find this product anywhere or a comparable alternative that's the same size. If you know where I can purchase another ball that I've described @ 12.5 in. diameter, please let me know! I'll likely buy this ball that was just delivered, today, in the future, if it's not discontinued! It's a great deal for only $14.99!! Thanks from a happy satisfied customer, V.B.

Sort of good for tough chewers??
Color: Deep Roots Carrot - Small, Size: Small Dog
The actual carrot part (orange part) is tough chewer approved and my dog loves. It’s basically the same shape and size as his kong. However the leaves (green part) is not tough chewer approved. He ripped ALL those leaves off and ate them within 5 minutes of me giving him the toy. However they passed through him fine.
