Magnetic Gear Speed Sensor IMG Series

Options
Dimensions and Wiring
Applications
DXF Data

Measurement from 0 Hz.
Noise suppression technology enables more accurate gear rotation measurement.

Composed of Hall elements, a magnet, and signal processing circuitry, it converts magnetic variations caused by rotation of a ferromagnetic detection gear into electrical signals for logic output.

Capable of detection from 0 Hz, with jitter suppression technology enabling precise rotation measurement.

A line driver output type is available for stable operation even with long wiring distances.

Equipped with a reverse-connection protection circuit to prevent failures caused by wiring mistakes.

Features

Excellent noise immunity

The detection section resists magnetic field noise and suppresses jitter.
Line-driver type ensures high resistance to transmission noise.


 

Detectable frequency range: 0 - 20 kHz

Accurate detection from start to stop of movement.

Operating temperature range: -20 °C to +105 °C

Stable detection even in high-temperature environments.
Contact us for models with extended temperature ranges.

Reverse-connection protection circuit

Prevents failures caused by wiring mistakes.
 

IP67

Sensor detection surface: fully sealed, integrated metal housing.
Cable: uses our original "Conical PressTM" technology.
 
Sensor Detection Surface / Conical PressTM

Three output types available

- Line driver output
- Semi-open collector output
(open collector + pull-up)
- Differential (balanced) CMOS logic output

Capable of detecting objects other than gears

Can detect ferromagnetic gears of module m0.5 or larger, and ferromagnetic objects with uneven surfaces (1-2 teeth, holes, etc.).

Operation-check LED on the sensor body

Allows checking the operational state while observing the gear.

Note
Extending the sensor cable increases susceptibility to external noise.
The impact depends on conditions, so it is recommended to verify performance in the user's environment.
