Waterproof LSR Overmolded Ultrasonic Transducer Assembly

Waterproof LSR Overmolded Ultrasonic Transducer Assembly is designed around the requirements of ultrasonic distance measurement sensors, medical ultrasound equipment components, and automotive parking and detection systems. As a electronic and electrical assembly component, the design is defined by encapsulation material: Liquid Silicone Rubber (LSR); process: LSR Injection Overmolding; operating temperature: -40°C to 200°C and should be evaluated as part of the complete product or equipment assembly.

A successful custom part depends on more than the outer shape. The sealing path, contact surfaces, wall sections, bonding areas and installation method all influence how the component performs in service. The points below summarize the component in an engineering-focused format for RFQ and supplier comparison.
