Model E-188 and TR-2465 are ultrasonic air transducers that operate at frequencies of 220 kHz and 150 kHz respectively. A unique design feature results in the air transducer having a narrow directional pattern completely free of side lobes. The transducer face is silicon. These air transducers are typically used in non-contact echo ranging or web detection applications, and are RoHS compliant.

The TR-2436 is a 150 kHz transducer that features a plastic housing that can be waterproof when mounted in an appropriate housing.
