GL-BC122-XX
For projects where raw inertial sensor data is sufficient, compact MEMS sensing element units (SEU) are manufactured — model GL-BC122-XX.
The GL-BCh122 (-20, -40, -60) SEU units are carefully calibrated over the operating temperature range of -40 to +55 °C.
They output (1000 Hz) accelerations and angular rates in the body-fixed (sensor) coordinate frame.
GL-BCh122 is designed to operate from an onboard supply powered by a single battery — 3.7 V (range from 2 to 5 V).
Lightweight — 40 g, dimensions — 44×40×16 mm; RS-422 (RS-485) interface and a configurable data communication protocol.
