Frequently asked questions
What is the CLA021 M12 lens mount hole spacing?
The CLA021 uses 20mm hole spacing with a 17mm × 17mm footprint, and it accepts M1.7 mounting screws. That spacing fits many standard board-level camera PCB layouts.
What material is the CLA021 lens holder made from?
The CLA021 is made from LCP, or liquid crystal polymer, which is a low-CTE engineering thermoplastic. It stays dimensionally stable across -40°C to +85°C and handles thermal cycling better than ABS or nylon holders.
Is the CLA021 compatible with all M12 lenses?
Yes. The CLA021 accepts any M12x0.5 threaded lens, including all Commonlands M12 lenses. The thread depth fits standard S-mount lens barrels.
What is the CLA021 profile height?
The CLA021 has a 7.4mm profile height. That low stack height helps in space-constrained camera modules.
How does the CLA021 compare to the CLA018 lens holder?
The CLA021 uses 20mm hole spacing, and the CLA018 uses 18mm spacing. Both use LCP construction and have similar thermal behavior, so the board hole pattern is the real deciding factor.
Does the CLA021 M12 lens mount ship same day?
Yes. Commonlands ships all in-stock accessories same day from San Diego for orders placed before 12 PM PST. The CLA021 currently has 820+ units in US stock.
