Industry Background: Miniature Ultrasonic Sensing for Compact Equipment

Nowadays more and more compact smart devices demand small‑size ranging components that keep stable detection performance within limited PCB space. Conventional large‑size ultrasonic sensors cannot fit miniaturized product designs. As SWT’s smallest ultrasonic ranging transducer, this 10 mm USC10T/R‑40MPWA sensor delivers reliable transmit‑receive performance while taking up very little installation space, ideal for space‑constrained ranging and obstacle‑avoidance projects.

Core Electrical Performance Parameters

This miniature 10 mm ultrasonic sensor features center frequency of 40±1.0 KHz. Transmitting sound pressure level ≥90 dB, reception sensitivity ≥‑60 dB. Its ‑6 dB directivity reaches 70±10°, ringing time ≤1.2 ms. Capacitance is 2000±20% pF at 1000Hz. Maximum allowable input voltage is 150 Vp‑p. Working temperature covers wide range from ‑40℃ to +80℃. Pin terminal design supports direct through‑hole soldering on control boards.

Structural & Performance Advantages

As SWT’s smallest ranging ultrasonic transducer, its 10 mm outer diameter greatly saves installation space for miniaturized end products. Robust aluminum alloy shell brings excellent shock resistance and environmental adaptability. The wide operating temperature range enables stable operation under extreme cold and high‑heat conditions. Optimized 70° beam angle balances detection coverage and anti‑interference capability, while low ringing time improves short‑distance measurement accuracy. Pin‑out structure is friendly for high‑volume SMT/through‑hole production.

Wide Application & Procurement Support

This 10 mm smallest ultrasonic ranging sensor is widely applied for mini smart devices, small‑size obstacle‑avoidance modules, compact parking auxiliary equipment, consumer‑grade robot ranging, intelligent sanitary appliances and other space‑limited distance‑detection devices. Both sample evaluation and bulk purchasing are available. With stable production capacity, strict quality management and factory‑direct pricing, it becomes an excellent miniature sensing solution for global customers.
