"MTRS-614 is the ultra small and lightweight rate sensor assembly. The sensors are characterized by high sensitivity and very low intrinsic noise level. The sensor is available in two versions. The MTRS614B is optimized to achieve low self noise, while the MTRS614A has lower g-sensitivity and consequently can deliver better performance where vibration is a factor in conditions."
