The GU1008C-40T & GU1008C-40R ultrasonic sensors manufactured by INGHAi are electronic components used for distance measurement. They feature a Through Hole design and are RoHS compliant. Both components include a transmitter and receiver, which emit an ultrasonic signal and detect the reflected signals, respectively. The 40T and 40R represent the electrical characteristics of the parts, with T denoting Transmitter and R denoting Receiver. The distance range for these components is 0-8 mm (determining by the emission frequency). They operate reliably over a wide temperature range of -20°C to +90°C.Additionally, these sensors can withstand shock and vibration up to 10 g. They have no electrical contact during operation, making them ideal for applications where low-noise operation is required. The GU1008C-40T & GU1008C-40R can also detect small objects from a long range, which makes them suitable for robotic applications.
