Industrial Smart Color Mark Photoelectric Sensor (8-16mm, NPN)

The Industrial Smart Color Mark Photoelectric Sensor is an optical detection device engineered for reliable registration mark recognition. Operating on 12-24V DC with an NPN output, it provides accurate tracking over an 8-16mm sensing distance. It is well suited to makers, engineering students, and technicians building automated packaging, sorting, or inspection mechanisms.

Targeted 8-16mm sensing distance

The sensor operates effectively within an 8-16mm detection range. This close-range focus ensures accurate tracking of passing targets on conveyors and production lines.

Industrial NPN output interface

Equipped with an NPN switching output, this device interfaces cleanly with microcontrollers, PLCs, and digital logic circuits. It delivers rapid, reliable triggering for downstream control hardware.

On-board LED display

An integrated LED display provides immediate visual feedback on the sensor status. This assists with quick optical alignment, setup, and live monitoring.

12-24V DC operating input

The unit operates on a standard 12-24V DC power supply. This wide direct-current input matches typical industrial control panels and bench power supplies.

Packaging and inspection applications

Engineered for high-contrast color mark identification, this sensor suits automated packaging, labelling, and quality inspection machinery. It ensures consistent triggering on registration marks across various materials.
