Estos sensores que utilizo para medir RPMs funcionan realmente bien por el precio que tienen.

Used it as a temp for a Dyno it was fine for anything up to about 750cc but could not handle most 1000cc +It is not designed for use at the speeds that a Motorcycle Dyno can run but it held up well, the speed is pretty accurate up to about 155,then it gives up. I have had to change to a different sensor but keep a couple of these just in case.

I hadn't noticed that the photo-interrupters are mounted on little printed circuit boards. I don't know what voltage they can work off, but they seem happy with my Raspberry Pi's 3.3V. Just 3 connections: power, ground and output.In case anyone's interested in the dimensions, the mounting holes are 3.2mm diameter, 21mm between centres, and the gap for the slotted wheel is 6mm wide.

They work well. Making and breaking the beam produces a nice clean square wave on my oscilloscope.

I am pleased with this purchase. The optocouplers worked without a problem and they fitted neatly in the pre-cut holes in the robot car kit I bought (see image above) -something I was concerned about. The wheel encoders are fine, made of good quality plastic and they fit those yellow gear motors that are so popular.I would recommend this product for purchase.
