FAQ
Q: Which sensor does the IV4-L4M work with?
A: It is listed for the IV4-400MA smart camera. Check your camera model before buying. Other IV4 heads may not match the mounting or connector.
Q: Does the ring light keep IP67 with any filter?
A: No. IP67 applies only when attached to the applicable sensor. It does not hold when polarizing filters OP-88644, OP-88645, OP-88646, or OP-88647 are installed.
Q: When should I choose infrared over white light?
A: Pick infrared for shiny metal, glossy plastic, or low-contrast marks. It cuts glare and boosts stable detection. White light may still suit color inspection.
Q: How do I know the light is genuine and working?
A: Oiltech Controls checks each unit before shipment. We test fit, LED output, and housing condition. You get a 12-month warranty for extra cover.
Q: What if my IV4 system is discontinued?
A: We support obsolete control systems. Tell us your camera model and current setup. We help match a tested surplus or refurbished IV4-L4M option.
