DC-SG-300kPS High Sensitivity
A high-sensitivity ultrasonic gas transducer designed for floor-cleaning robots and smart devices, focusing on precise material identification and wide dynamic ranging. Features a PC plastic housing and glass-reinforced epoxy acoustic window, operating at 290kHz (±10%) with a 2cm–4m ranging capability. Echo sensitivity >1.2Vpp (5cm distance) and a 9°±3° narrow beam angle enable accurate differentiation of surface characteristics (e.g., carpet, tile), meeting stringent consumer electronics durability standards. Twisted-pair shielded design suppresses EMI, weighs only 2g, and integrates seamlessly into smart devices, delivering reliable non-contact sensing for obstacle avoidance, material recognition, and automation.
