High RPM Rotary Encoder?

Need a new type of sensor? Interfaced a sensor that you want to tell everyone about?

If you are measuring RPM of a nitro rc car engine then you need to use a micro infrared sensor like the Spektrum 1452 and the phidgett high speed encoder.

Has anyone connected the Spektrum 1452 or FrSky RPMS-01 Sensor to Phidgets?
I need to measure the RPM of 4 motors. Current motors run unloaded at 19000 RPM.
I am thinking the sensors will work with a Phidgets 1057 High Speed Encoder?
Does anyone know?

After a few searches, it looks like the Spektrum 1452 is designed specifically to be used with spectrum receivers, in remote-control applications. There is very little information on how this sensor operates, but it certainly does not look like something that would be compatible with Phidgets Inc. encoder interfaces.

The FRSky RPMS-01 appears to be a light sensor of some sort, designed to be pointed at a surface with a reflective strip or light source on it. While it's possible that this sensor may work with a Phidget InterfaceKit like the 1018, this product also seems to have very little documentation available online.

If you want to search for encoders that are compatible with the 1047 or 1057, search for quadrature encoders, with an open-collector or push-pull type output.
