BZJ-311 Color Mark Sensor
VIOX BZJ-311 Series Color Mark Sensors offer a 9mm detection distance and utilize a coaxial reflex sensing method with red, green, blue, and white light sources. Featuring adjustable sensitivity, response time of 50µS, and supply voltage of 10-30Vdc±10%, these sensors are ideal for detecting opaque objects. Rated output currents include 300mA for N.P Type, 400mA for A Type, and 2A max for J Type. Built with reverse polarity protection, surge suppressor, and short-circuit protection, they have an IP67 rating and operate from 0 to 50°C. Constructed with an aluminum die-cast case and PMMA lens.
