While inverters are widely used for motor control as energy-saving measures, they are also sources of electrical noise.
Consequently, inquiries regarding noise countermeasures in measurement applications have been increasing.
In rotational speed and angle measurement, many encoders feature line driver signal outputs, but they often cannot accommodate EV or high-speed motors.
Here, we introduce gear sensors with line driver outputs that adopt differential methods for both sensing and transmission, making them less susceptible to noise.
Measurement from 0 Hz
Detectable from 0 Hz; precisely measures right from the start of rotation through to stopping.
Stable Detection with Reduced Jitter
The sensor part utilizes a 2-Hall element differential method. Unaffected by ambient magnetic fields, it ensures stable detection with reduced jitter.
Reliable Long-Distance Transmission
Line driver output is resistant to transmission noise, allowing safe and reliable use even over long transmission distances.
Rotational Speed Measurement
Pair with the TDP-4921-ND-□□ (line driver input & isolated input support) for even greater noise immunity during measurement.

Adopts a 2-Hall element differential method to eliminate magnetic field noise at the sensing part, providing a stable output with suppressed jitter.
The LD type with line driver output also eliminates the effects of transmission noise, making it suitable for long-distance wiring.
The sensor detection surface features a completely sealed single-body metal case with IP67 rating, supporting environments exposed to water or oil.
