Frequently asked questions
What sensors does the CIL337 automotive M12 lens support?
The CIL337 fits 1/2.5 inch sensors up to 3MP at 2.1μm pixel pitch, including the Sony ISX031 and ON Semiconductor AR0234. Those sensors are common in automotive ADAS camera modules.
Is the CIL337 weatherproof for exterior vehicle mounting?
Yes. The CIL337 M12A variant carries an IP69K rating, so it is sealed against dust and high-pressure water jets used in exterior vehicle testing.
What is the field of view of the CIL337 4mm M12 lens?
The CIL337 gives 133° field of view at the 7.2mm image circle. You should model the exact horizontal and vertical angles on your sensor at field of view calculator
Can I use the CIL337 for ADAS surround-view cameras?
Yes. The 133° field of view, F/1.6 aperture, and IP69K sealing make the CIL337 a strong choice for surround-view, parking assist, and other ADAS cameras that need wide coverage.
Does the CIL337 ship same day from the US?
Yes. Commonlands ships in-stock lenses same day from San Diego, California for orders placed before 12 PM PST.
What lens holders work with the CIL337?
The Commonlands CLA019 is one compatible holder for the CIL337, and other M12 mounts work as well. e-con Systems boards need a 10–15mm tall holder, while FLIR Blackfly S, Allied Vision Alvium, iDS, The Imaging Source, and Basler Dart cameras accept the M12A mount directly.
