The device therefore supports vending machines with simple payment systems or cash registers that rely on discrete coin value detection.\u003c\/p\u003e \u003cp\u003eThe module detects coins by weight and diameter, checks the denomination, and reports the result through pulses on the 4-bit data bus as well as handshake signals for data transfer. Since the coin value is output directly, time-consuming post-processing in the control code is no longer necessary.\u003c\/p\u003e \u003cp\u003eOperation requires 12 V DC. The data outputs use standard logic levels and can be connected directly to the digital inputs of microcontrollers or single-board computers. The device is suitable for beverage vending machines, parking barriers, washing machine coin mechanisms, or simple vending machines in environments where fast and reliable coin detection without complex software logic is required.\u003c\/p\u003e \u003cp\u003eA 12 V power supply and connecting cables for the data bus and handshake signals are required. A laboratory power supply is sufficient for prototypes; for productive operation, a stable power source with sufficient current capacity for the number of coins processed per minute should be selected. The module is limited to coin values up to CHF 5.00 and processes Swiss denominations only.\u003c\/p\u003e \u003ch3\u003eSafety notice\u003c\/h3\u003e \u003cp\u003eThe device is intended exclusively for building prototypes and for testing and development purposes. It is not intended for direct connection to power supplies without protective measures. Work on or near electrical installations must be carried out by qualified electricians; if there is any uncertainty regarding the power supply, consult a qualified electrician before commissioning.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x CH926 coin counter\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66045643456861,"sku":"F23107796","price":23.4,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/muenzzaehler-ch926-funduino-5100949.png?v=1791490636","url":"https:\/\/funduino.com\/en\/products\/coin-counter-ch926","provider":"Funduino","version":"1.0","type":"link"}
