Advanced Silicone Seal Rings for Lens Modules

This is a precision seal ring especially used in lens modules of the on‐vehicle camera modules. The camera is one of the key parts and keeps operating safely and steadily to play functions involved with driving safety, that is, vision. Since the function of vision involves long‐time test on road, the lenses suffer exposure from various harsh conditions when used in on‐vehicle vehicles, for example, sand and dust attacks, falling down at rainy snow weather, shaking vibration on bumpy roads, being moved by vehicle engine rooms at high temperature, and others. On condition of providing reliable waterproof and dustproof sealing effects, this seal ring can protect the lens itself from harm from the external conditions (sand and moisture), etc. Performance of the seal ring is directly related to image of on‐board vehicle image; it helps avoid equipment failure or camera malfunctioning due to entering harmful impurity in camera or shaking of the lens assembly by road shaking and helps increase service life of the equipment and provides support for such visualizing functions as the assisted driving and driving recording.

Product Features:

1、Exceptional sealing capability：Maximum sealing effects are ensured by ensuring the maximum control for designing tolerance on seal key sizes. DOIT's Precision automotive seal achieve an industry leading design tolerance ensuring tight sealed, snug fit with housing and edge of the lens.

2、Extreme environment endurance： The Lens Module Seal Rings always remain elastic— that is, not hardened or softened— even after experiencing the extreme heat or cold cycling range of -40℃ to +120℃, which prevents gaps from occurring in the expanding and contracting temperature conditions of any type, prevents risks from appearing, eliminates seal issues, and constantly guarantees the adherence state between sealing surfaces.

3、Deformation resistance: With a compression set controlled at 25% or lower, these Automotive Seal will not experience irreversible deformation when compressed for long periods and under continuous vehicle vibration, thus they won’t be loose or shift off the sealing surface.

4、Multi-layer contamination protection: The product delivers comprehensive defense against dust, water, moisture, and oil, safeguarding against infiltration of dust, rainwater, fog, or engine oil into the lens interior. This prevents issues such as blurred imaging, light spots, circuit shorts, or sensor corrosion.

This Precision O-Ring Seal combines the above characteristics and provides reliable seals for cars and becomes an important product to create high performance Automotive Sealing Assemblie, thereby enhancing the identity of excellence among Seals as selected by the Seals.
