IR Cut-Off Filter Switcher for M12 Lenses

IR Cut-Off Filter Switcher, 18mm Hole Spacing, 9.5mm Height, 1/1.7" Format

The CLA219-ICR is an M12 Lens IR Cut-Off Filter Exchanger (Switcher) with 9.5mm height. The exchanger has 0.21mm thickness IRC filter with a 0.21mm dummy glass filter. The CLA219 uses a linear magnet for drive mechanism, resulting in better lifetime than coil based rotary switchers. The large glass size is suitable for 1/1.7" type sensors. The switcher is controlled using an h-bridge that has 3.3V (forward polarity for open, reverse for close) and has a 60mm long 2-pin 1.25mm JST connector.

Frequently asked questions

What is the CLA219-ICR IR cut-off filter switcher?

The CLA219-ICR is a linear-magnet IR cut-off filter exchanger for M12 lens assemblies. It swaps between a 0.21mm 650nm IRC filter and a 0.21mm dummy glass for day and night camera operation.

How does the CLA219 differ from the CLA216 filter switcher?

The CLA219 has 18mm hole spacing, 9.5mm height, and a larger glass aperture for 1/1.7 inch sensors, while the CLA216 has 20mm hole spacing, 7.6mm height, and a 0.30mm IRC filter. The CLA219 also uses a linear magnet drive, which generally lasts longer in the field.

How do I wire the CLA219-ICR?

You connect the 2-pin 1.25mm JST connector to an H-bridge driver and apply 3.3V for 100-500ms. Positive on the red leadwire opens the filter, and reverse polarity closes it.

What sensors does the CLA219-ICR support?

The CLA219 glass aperture supports sensors up to 1/1.7 inch format. It works with any M12 lens ordered in the M12ANIR variant and pairs with holders such as the CLA019 or CLA024.

How many lifecycles does the CLA219-ICR last?

Commonlands guarantees at least 50,000 switching cycles. The linear magnetic drive typically exceeds 100,000 cycles in the field, but the guaranteed number remains 50,000.

Does the CLA219 ship same day from the US?

Yes. Commonlands ships in-stock accessories same day from San Diego for orders placed before 12 PM PST.

The CLA219-ICR is an M12 lens IR cut-off filter exchanger with 18mm hole spacing and 9.5mm height. It uses a linear magnet drive instead of the rotary coil mechanism found in cheaper switchers, and that change matters because cycle life is usually the first thing that fails in day and night camera hardware.

The unit switches between a 0.21mm IRC filter and a matched 0.21mm dummy glass, so back focal length stays consistent between day and night modes. You drive it with a 3.3V pulse for 100-500ms through the 60mm long 2-pin 1.25mm JST connector. Positive on the red leadwire opens the filter, and reverse polarity closes it. Coil resistance is 20Ω±10Ω, operating voltage is 3.0-5.0V, and the D263T glass substrate has a T=50% cutoff at 645±10nm.

The larger glass aperture, compared with the CLA216, makes the CLA219 a better fit for 1/1.7" and larger sensors where the optical path widens quickly. Commonlands guarantees at least 50,000 lifecycles, and the linear magnetic mechanism typically exceeds 100k in field deployments.

The CLA219 pairs with any Commonlands M12 lens in the M12ANIR variant plus a CLA019 or CLA024 lens holder for a complete day and night camera module. You can plan field of view at field of view calculator and depth of field at depth of field calculator

The CLA219 is in stock at our San Diego warehouse. Orders placed before 12 PM PST ship same day.
