Epson gyroscope sensors are divided into conventional and automotive gyroscope sensors and inertial measurement units (IMUs) in terms of usage. Divided by the number of detection axes, it can be divided into single axis gyroscopes, three-axis gyroscopes, and six axis gyroscopes (three directional angles+three directional accelerations);

There are two types of conventional single axis gyroscope sensors: X2A000271001200 (XV7011BB 49.600kHz K) and X2A000261001200 (XV7001BB 49.600kHz K), both with external dimensions of 5.0 * 3.2. The previous XV-3700CB was discontinued in 2021, and it is recommended to replace it with two single axis gyroscope sensor models, XV-3510CB and XV7011BB, in the future.

EPSON has a wide range of models for automotive gyroscopes, including the XV4001BC, which meets the AEC-Q200 standard XV4001BD、XV4001KC、XV4001KD。 The ones that meet the AEC-Q100 standard include: XV-9100CD XV9300LP、XC1011SD、 Wait.

For inertial navigation purposes such as autonomous vehicle, logistics robots and AGV carriers, EPSON currently sells three models of inertial measurement units, namely M-G370, M-G365, M-366 and M-G330. The former has an accuracy of 0.8 °/hour.

Epson's (EPSON) gyroscope sensor has superior temperature characteristics and low noise characteristics, and has been widely used in many application fields, such as optical stabilization correction for digital cameras. Optical anti shake correction is a processing system that uses a gyroscope sensor to detect hand shake during shooting, and then moves the lens or image sensor to counteract the shake and reduce its impact. The number of segments is one of the indicators that represents the ability of anti shake correction. One correction indicates that even if the shutter speed is doubled, its jitter will remain the same as when it was not corrected. The anti shake correction system using precision Epson gyroscope sensors can perform 4-stage correction (equivalent to 16 times the shutter speed), achieving more than twice the effectiveness of existing systems. In addition to the stabilization and correction of digital cameras, gyroscope sensors are also used for various other purposes, such as car navigation, remote control for home TV game consoles, 3D mice for computers, vacuum cleaners, or hobbies.
