## **Description** 

**Transmitter Sensor SQ-40-T-10B SQ-40-R-10B** 

Ultrasonic ceramic transducers transfer acoustical energy to mechanical energy or vice versa. The Standard Open Type Transducer is constructed in a manner which incorporates the fundamental structure of piezoelectric ceramic element of the monomorph type with a conical metal resonator. This Special combination provides high sensitivity (Over – G5dB/V/µBar), wider bandwidth, excellent temperature and humidity durability, stable electrical and mechanical characteristics, and small size. 

## **Applications:** 

- Remote control devices 

- Liquid & bulk sensors 

- Level controls 

- Intrusion alarms 

- Motion detectors 

## **Housing QHP10** 

- Auto doors 

• Counting devices
