The KEYENCE CZ-V21AP RGB Digital Fiberoptic Sensor is designed for high-speed and precise detection applications. This main unit amplifier features a PNP output and offers multiple response time settings, including 200 µs (HIGH SPEED), 1 ms (FINE), 4 ms (TURBO), and 8 ms (SUPER), ensuring optimal performance in various environments. The sensor is equipped with a PNP open-collector control output with four channels, capable of handling up to 30 VDC and 100 mA per output, with a total of 200 mA across all outputs.Built with robust protection circuits, including reverse-polarity protection, overcurrent protection, and surge absorbers, the CZ-V21AP ensures reliable operation in demanding industrial settings. The unit supports external tuning input, external bank switch input (C/C + I-mode), and external shift input (super I-mode), with an input time of 20 ms minimum. Additionally, the sensor offers versatile timer functions, including OFF-delay, ON-delay, and One-shot, with adjustable timer times ranging from 1 to 1000 ms for each bank.The CZ-V21AP allows for the expansion of up to three additional units, making it a scalable solution for complex detection systems. It features a durable polycarbonate housing and cover, ensuring long-lasting performance. The sensor is designed to operate within a temperature range of -10 to +55 °C (14 to 131 °F) and can withstand vibrations of 10 to 55 Hz with a double amplitude of 1.5 mm (0.06") for 2 hours in each of the X, Y, and Z axes.Ideal for applications requiring precise color detection and differentiation, the CZ-V21AP is a reliable choice for industries such as packaging, automotive, and electronics manufacturing. Its compatibility with DIN rail mounting and compliance with CE and UL standards further enhance its versatility and ease of integration into existing systems.
