Advantages:

Suitable for both AC and DC systems – versatility in installation
No programming required – simple connection is sufficient
Compact size – easy integration into panels and consoles
Retains counts even after power off
Simple setup and installation without complex configuration
Disadvantages:

Limited counter range (up to 9999) – may not be suitable for large quantities
No compatibility with network data transmission (Wi-Fi, Modbus, etc.)
Designed only for general counting function – does not offer analytical functions
Suitable only when a clean signal from the sensor can be ensured
The infrared 4-digit counter is a compact, efficient, and easy-to-install solution for industrial automation. With wide signal support (from dry contacts to AC/DC pulses) and robust construction, this device is ideal for counting objects in moving systems. It is an excellent choice for both professional installers and engineers who value reliability without complex programming.
