The Omron E3ZM-V81 5M is a compact, high-speed color mark photoelectric sensor designed to detect color contrast and registration marks with extreme precision. Featuring a diffuse reflective sensing method and a white LED light source (450โ700 nm), this sensor offers a sensing range of 12 ยฑ 2 mm, making it ideal for packaging, labeling, and printing applications where accurate color mark detection is critical.
This model operates on a 10 to 30 VDC power supply and features a PNP output configuration. It connects via a 5-meter pre-wired cable and consumes a maximum of 750 mW (25 mA at 30 VDC). The control output supports up to 100 mA at 30 VDC with a residual voltage of 2 V max. The sensor is configured using a simple teaching method, allowing quick setup for target colors and background calibration. It supports Light-ON or Dark-ON logic set through teaching, and responds in just 50 ยตs, ensuring performance in high-speed production lines.
Indicators include a yellow operation indicator, green stability indicator, and red teaching indicator for user-friendly setup and diagnostics. It withstands ambient light up to 10,000 lx and operates reliably in extreme temperature ranges from โ40ยฐC to 60ยฐC. The E3ZM-V81 5M also meets industrial standards for humidity resistance (up to 85% RH operating, 95% RH storage) and electrical insulation (20 Mฮฉ at 500 VDC, 1,000 VAC dielectric strength).
With vibration resistance (10โ55 Hz, 1.5 mm double amplitude) and shock resistance up to 500 m/sยฒ, this sensor performs reliably in harsh environments. Protection circuits include reverse polarity, output short-circuit, and output polarity reversal safeguards. Built with durable materials such as SUS316 stainless steel and chemical-resistant polymers, the housing meets IP67 and IP69K protection ratingsโperfect for food, beverage, and washdown applications.
The Omron E3ZM-V81 5M is a top choice for fast, accurate, and reliable color mark detection in demanding automation systems.
