The RM5B HD in Housing B is an electronic coin and token validator by Comestero, designed for devices requiring high resistance to counterfeit coins and fast operation. The HD series was developed for the vending, amusement, and automated fare collection industries, where precision, diagnostics, and operational stability are paramount.
The model recognizes coins at a speed of up to 6 coins per second and utilizes an advanced measurement system based on five sensors and the analysis of ten comparative parameters.
Application
The RM5B HD coin validator is used in:
vending machines
amusement and gaming machines
fare collection systems
self-service devices operating in continuous mode
OEM projects requiring high levels of anti-fraud security
Housing B – coin track
Housing B allows for coin insertion from both the top and the front of the device. Once inserted, the coin passes through the validation track and security system, and is then directed to the appropriate outlet at the bottom of the validator.
accepted coins are directed to the lower outlet, into a cash box, container, or separator
rejected coins are also directed to the lower return outlet within the machine's structure
This layout is ideal for devices where both the accepted coin path and the return path are located in the lower part of the housing.
