This product is a high-performance ultrasonic transducer assembly encapsulated with LSR (Liquid Silicone Rubber) overmolding technology.

It is designed to provide stable ultrasonic signal transmission and reception while offering excellent environmental protection, including waterproofing, dust resistance, chemical resistance, and mechanical shock resistance.

By encapsulating the transducer with medical/industrial-grade liquid silicone rubber, the structure ensures long-term reliability in harsh operating conditions without compromising acoustic performance.
