TCT TCT40-16T/R Piezoelectric Ultrasonic Sensor Transceiver

Description

Description

The TCT TCT40-16R is a 40kHz ultrasonic sensor transceiver designed for precise distance measurement and object detection. It integrates both emission and reception functions, with a narrow beam angle of 60 15 and a typical detection range of up to 4 meters in air. The sensor operates at 5V DC with low current consumption, producing a sound pressure level of at least 112dB and a receiving sensitivity of -65dB. It features a capacitance of 2400pF 20% and supports operation in temperatures from -20C to +70C. The module is compatible with standard microcontrollers and embedded systems, making it suitable for robotics, automation, and level sensing applications.
