ZENITH - 49-1267-02 Ultrasonic Transducers

In the early 1960s, solid-state circuitry (i.e., transistors) began to replace vacuum tubes. Handheld, battery-powered control units could now be designed to generate the inaudible sound electronically. Ultrasonic remote control lasted through the early 1980s or a quarter century from its inception. More than 9 million ultrasonic remote control TVs were sold by the industry during the 25-year reign of this Zenith innovation. By the early 1980s, the industry moved to infrared, or IR, remote technology.

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.
