Automotive Lens – S03712310120

S03712310120 is 3.7mm Wide-angle HD lens 1/2.3″ F2.0 High-Resolution M12/S-mount lens, 5 Megapixel IP67 Durable waterproof automotive lens.

3.7mm IP67 Waterproof Automotive Lens

This 3.7mm 5MP M12 IP67 waterproof automotive lens is designed for compact vehicle imaging systems that require wide-angle coverage, high-resolution imaging, and protection against water and dust. Supporting 1/2.3″ and 1/2.7″ image formats, the lens provides flexible integration across different automotive camera platforms while maintaining broad scene coverage.

With a 3.7mm focal length, the lens delivers a 132° diagonal FOV on a 1/2.3″ sensor and a 120° diagonal FOV on a 1/2.7″ sensor. Its F2.0 aperture, 0.2m minimum object distance, and M12×0.5 mount make it suitable for compact vehicle cameras and embedded imaging modules. The IP67 waterproof construction adds an important layer of protection for outdoor and automotive environments where exposure to dust, rain, and moisture is expected.

Waterproof Automotive Lens Applications

IP67 Wide-Angle Imaging for Automotive Systems

The combination of a 3.7mm focal length and wide field of view makes this lens suitable for automotive cameras that need to capture a broad area around the vehicle. When paired with a 1/2.3″ sensor, it provides a 132° diagonal FOV, 101° horizontal FOV, and 74° vertical FOV.

This wide coverage can help camera systems observe nearby objects, vehicle surroundings, parking areas, and other scenes where a broad viewing angle is more important than long-distance telephoto imaging.

The IP67 waterproof rating makes the lens particularly suitable for camera assemblies installed in environments exposed to rain, road splash, dust, and changing outdoor conditions.

Designed for Automotive Vision Application

This lens is Designed for automotive vision application where wide-angle image coverage and environmental protection are both important. Its 5MP resolution provides additional image detail compared with lower-resolution compact camera lenses, while the M12×0.5 mount allows integration into small camera assemblies.

Potential automotive applications include:

• Surround-view and auxiliary vehicle cameras
• Parking assistance cameras
• Side-view imaging
• Front or rear wide-angle cameras
• Vehicle monitoring systems
• Outdoor automotive sensing cameras
• Commercial vehicle camera modules
• Off-road vehicle imaging
• Industrial vehicle cameras

For broader automotive vision requirements, see TOWIN’s ADAS optical solutions.

Compatible Device Types

The lens can be considered for integration with:

• Automotive camera modules
• Vehicle monitoring cameras
• Parking cameras
• Surround-view camera systems
• ADAS-related imaging devices
• Commercial vehicle cameras
• Outdoor embedded cameras
• Industrial vehicle vision systems
• IP67-protected camera assemblies

Wide-Angle Coverage for Vehicle Imaging

The lens provides different FOV performance depending on the sensor format.

With a 1/2.3″ sensor, the 3.7mm focal length produces:

• 132° diagonal FOV
• 101° horizontal FOV
• 74° vertical FOV

With a 1/2.7″ sensor, it provides:

• 120° diagonal FOV
• 97° horizontal FOV
• 52° vertical FOV

This dual-format compatibility allows camera designers to select the sensor according to the required image area and system architecture while retaining the same basic lens platform.

Because wide-angle automotive lenses naturally produce greater geometric distortion than narrow-angle optics, this lens should be selected for applications where broad scene coverage is more important than precision geometric measurement. The specified distortion is <-31%.

For projects where distortion is a critical design parameter, consult the Distortion Guide before selecting the final lens.

IP67 Protection for Outdoor Automotive Environments

The IP67 waterproof rating is one of the key differentiators of this lens. It is designed for camera assemblies that may encounter dust, rain, water splash, or other outdoor environmental exposure.

For automotive applications, optical performance alone is not enough. The lens and camera assembly must also be considered in relation to the installation environment, housing design, sealing structure, and overall environmental protection requirements.

This lens is therefore particularly relevant to vehicle-mounted and outdoor camera platforms where a compact M12 optical interface and IP67-rated protection are required.
