Commercial Ultrasonic / Audio Transmitter & Receiver Probe

Transducer Receiver consist of a piezoelectric ceramic disc mounted with-in a probe.  A conical metal resonator bonded at the center of disc acting as a rigid piston. This special construction provides high sensitivity, wider bandwidth and excellent durability in wide temperature and humidity ranges and high stability in electrical and mechanical characteristics. Due to its free vibration character the open type transducers are very suitable for continual wave driving, such as Doppler motion detector.

High Quality Distance Ultrasonic Sensor Head

Marked in Red: "2-5-10cm. 3-8 Vol. 1-2 Inch & 2 - 12 Feet.

Has two DIN Male connectors, a 5-pin and a 3-pin plug attached to the special microphone with a 5 foot long flat cable with widely separated conductors.

Specific Application and Specifications Unknown - Great for Hobbyist/Experimenters/Inventors 

Typical Ultrasonic Probe Applications: Measurement, Motion, Sensing & Instrumentation, Automation & Process Control, Robotics, Security, Power Management, Leak Detection. and Inspection In Industrial, Aerospace, Medical, and Manufacturing.
