Rotation Detectors Notes on Detection Gears Detection Gear •In theory, a detector is a magnetic body. Since it has a large magnetic permeability, soft metals (such Rotation Detectors as S20C, SS41) are generally used. When performing normal rotating speed measurements, if the gate time is specified at 1 second, using a 60 P/R gear enables direct readout of the rotating speed by the counter. Shape •Fig. 1 showsof a Detection Gear various types of external rotors (detection gears and so detector output waveforms from Notes on Detection Gears forth). If the gear is a spur gear, an involute gear...

Electromagnetic Rotation Detectors The MP-900/9000 Series detectors have been designed primarily to detect frequency signals in proportion to the rotating speed by bringing the detector in close proximity to the addendum of a detection gear fitted to a rotating shaft (sine wave output). Various types are available, from general-purpose, oil-proof and heat-resistant types through to user-customized types, enabling you to select the one that best suits your application. Extension cables, signal cables and connectors can also be purchased separately. Rotation Detectors Mounting example •Features...

•The Relationship between the Gap and Detection Rotation Range ¥ MP-900/9000 Series: Rotating speed (r/min) that can be measured Rotation Detectors (1) The relationship between the gap between the detector and the detection gear and the detection range (Lowest measurable value) is given in the tables below. (2) The rotating speed range is that for which an output voltage of 0.5 Vp-p or greater can be maintained (load resistance = 10 k½). (3) The rotating speed that can be measured varies according to the type of display unit used. Note: When a 60-tooth gear is used Lowest measurable value Model...

Magnetoelectric Rotation Detector MP-981 For detection of low-to-medium speeds These detectors utilize magnetic flux response (the resistance value changes according to the magnetic flux). The internal mechanism comprises magnetic resistance elements, permanent magnets, a direct current amplifier, and a voltage regulator. Detection can be performed as square wave output over a wide range from ultra-low speeds to high speeds (1 to 20,000 r/min [60 P/R]). There are two models: the general-purpose MP-981 model and the waterproof AP-981 model. ¥ Output from ultra-low to high speeds (1 to 20,000 r/min...
