Frequently asked questions
What sensors work with the CIL359 6mm automotive M12 lens?
The CIL359 fits 1/2.5 inch sensors up to 3MP at 3μm pixel pitch, including the ON Semiconductor AR0341 and Sony ISX031. Those sensors are common in automotive ADAS and OMS modules.
Is the CIL359 sealed for exterior applications?
Yes. The CIL359 M12A variant is IP6K9K rated, so it handles dust, high-pressure water jets, and the thermal cycling that exterior vehicle and outdoor robotics systems see.
How does the CIL359 compare to 4mm wide-angle M12 lenses?
The CIL359 gives 78° field of view, while the CIL337 gives 133°. You choose the CIL359 when you need tighter framing and less distortion, and you choose the CIL337 when maximum coverage matters more than per-pixel detail.
Can I use the CIL359 for robotics navigation?
Yes. The 78° field of view, F/1.6 aperture, and 5g weight make the CIL359 practical for mobile robotics, AGVs, and forward-looking drone cameras.
Does the CIL359 6mm M12 lens ship from the US?
Yes. Commonlands ships in-stock lenses same day from San Diego before 12 PM PST.
What lens holder does the CIL359 require?
The Commonlands CLA019 holder is one compatible mount for the CIL359, and other M12 mounts work as well. e-con Systems boards need a 10–13mm tall holder, while FLIR, Allied Vision, iDS, The Imaging Source, and Basler cameras accept the M12A mount directly.
