DESCRIPTION AND ORIENTATION OF VARIOUS PZN-(5-7)%PT CRYSTAL TYPES AND THIER SYMBOLS
011P-32A /
011P-32S
[011]-poled transverse (32) mode crystal of [0-11]1 x [100]2(A) x [011]3(P). Type A is recommended for Actuator and Type S for Sensor applications, notably as motor section of underwater projectors and sensing elements of hydrophones respectively.
011P-31T [011]-poled transverse (31) mode crystal of [0-11]1(A) x [100]2 x [011]3(P) cut for transverse-mode transducers (31T) where high transverse loads are present.
011P-33T 011P-33T [011]-poled longitudinal (33) mode crystal of [0-11]1 x [100]2 x [011]3(A,P) cut for longitudinal mode transducers (33T) when relatively high d33 and crystal stiffness are advantageous.
001P-31T-110L 001P-31T-110L [001]-poled crystal of [110]1(A) x [1-10]2 x [001]3(P) cut as transverse-mode transducers (31T) where a high d31/sE11 value is advantageous.
001P-33T-100L



001P-31T-100L
001P-33T-100L
001P-31T-100L
[001]-poled crystal of [100]1 x [010]2 x [001]3(A,P) cut as longitudinal mode transducer (33T). Said cut may also be used as transverse mode transducer (31T), i.e., [100]1(A) x [010]2 x [001]3(P).

For other crystal compositions and cuts, please kindly contact us with your request.

Key on crystal designation / symbols:
  • 011P and 001P indicate poling direction being [011] and [001], respectively, which is also the 3-direction.
  • 33, 32 and 31 denote the mode of actuation/sensing, 33 being the longitudinal mode, and 32 and 31 are the transverse modes with the active direction being along the 2- and 1-axis.
  • A, S and T denote actuator, sensor and transducer, respectively.
  • 100L and 110L indicate the active length directions in [001]-poled crystals.
  • Superscripts (A) and (P) next to directional axes denote the active and poling direction respectively.
