Simple one-touch calibration with a dual digital display and ability to store up to 8 colors. Color, luster and fluorescent/UV sensing heads all connect to CZ-V20 Series amplifier. The CZ-V20 Series uses a completely different detection principle than other photoelectric sensors. This allows for. Amplifier Unit, Main Unit, NPN Amplifier Unit, Main Unit, PNP Amplifier Unit, Expansion Unit, NPN Amplifier Unit, Expansion Unit, PNP Reflective Sensor Head, Variable Spot Reflective Sensor Head with Shine Cancellation Reflective Sensor Head with Shine Cancellation, Small Spot Reflective Sensor. This manual describes the instructions, operating procedures and precautions for using the CZ Series. Keep this manual handy for future reference. With a coaxial design and a minimum spot diameter of just 6 mm, it enables precise object detection even at close distances.
