The RM5F HD in F-housing is an electronic coin and token validator by Comestero, designed for applications requiring high discrimination of counterfeit coins and high-speed operation. The HD series was developed for the vending, amusement, and ticketing industries, where precision, diagnostics, and operational stability are paramount.
This model identifies coins at a speed of up to 6 coins per second and utilizes an advanced validation system based on five sensors and the analysis of ten comparison parameters.
Applications
The RM5F HD coin validator is used in:
vending machines
amusement and gaming machines
ticketing and payment systems
self-service kiosks operating in continuous mode
OEM projects requiring high-level anti-fraud security
F-Housing – coin path
The F-housing allows for both top and front coin insertion. Once inserted, the coin passes through the validation path and security systems, and is then directed to the appropriate outlet.
accepted coins are directed to the bottom outlet, into a cashbox, container, or sorter
rejected coins are returned to the front of the device
This configuration facilitates installation in machines with a front-entry faceplate and ensures a clear, user-accessible coin return.
