ISU40-16TRBZ
40kHz Ultrasonic Reversing Radar Transducer | High Sensitivity & Reliable Obstacle Detection
Waterproof, Transceiver, Ultrasonic, Obstacle Detection, High Sensitivity, Reliable, Lightweight
The ISU40-16TRBZ is a high-performance 40kHz Ultrasonic Transducer (Probe) designed for OEM integration. Unlike standard sensors, this aluminum-encased component offers a massive 110° horizontal beam width, significantly reducing blind spots in automotive reversing radars and robot bumper systems. (Note: This is a raw component and requires an external driving circuit to operate.)
Engineered for durability and precision, the sensor features a waterproof, encapsulated design that ensures high reliability even in challenging environmental conditions. With superior sensitivity and a robust signal-to-noise ratio, it serves as the ideal detection core for enhancing vehicle safety and robotic navigation by effectively mitigating collision risks.

典型应用
As a versatile sensing solution, the ISU40-16TRBZ-T1 serves as the critical core for Automotive Reversing Radars, functioning as rear and corner bumper sensors for precise parking assistance. Its wide-angle coverage is equally vital for Robot Collision Avoidance, allowing manufacturers to build effective "electronic bumper" arrays for AGVs, delivery bots, and cleaning robots. Beyond direct integration, it stands as the foundational component for engineers developing custom Object Detection Modules and distance measurement systems.
