As piezoelectric materials, their application field is separated.

KP101-TRXXXX series, KP41-TRXXXX series: this is mainly used for sensor of creating electric signal from receiving the mechanical energy same as ultrasonic vibration and mechanical strain. they are called softener piezoelectric ceramics.
Use:
KP101-TRXXXX: sensor, medical device
KP41-TRXXXX: high sensitivity sensor
KP11-TRXXXX series, KP12-TR XXXX series: this is mainly used for transducer of creating mechanical energy same as ultrasonic vibration and mechanical strain from receiving electric energy. They are called hardener piezoelectric ceramics.
Use:
KP11-TRXXXX: knocking sensor on automobile
KP12-TRXXXX: ultrasonic cleaner, humidifier, welder
