Multi Coin Mechanism Acceptor, for Vending Machine, Message Seat

Description

Coin mech acceptor for vending machine, message seat

Introduction:

Name: multi-currency coin discriminator CPU with lateral vote

Applicable coin: diameter 18mm- 32mm; thickness 1.2mm-3.2mm. Applicable to RMB, various foreign currencies and so on.

Operating voltage: DC +12 V. Power consumption: static, 0.5mW; dynamic 0.5 W.

Operating temperature: -20 C ~ +50 C.

Features: 1, based on the material of the coin, to identify the true diameter of counterfeit money, high precision.

2, learning. Free to set the desired currency, coins do not need to compare with the sample clip, the CPU and memory are automatically set as coins.

3, can be set in three different coin specifications (you can also identify three different coins). 1-99 can be set to an output coin pulse signal or 1-9 coins emit a pulse signal.

4, the three sections of the pulse frequency signal output, switching output NO and NC regulator, a wide range. The signal output can be modified according to needs: signal output Pulse (or BYTE value) or RS232;

5, increase cumulative signal output and time control functions; prohibit coin acceptance function;

6, good anti-phishing effect. Can be connected to the counter, easy to send units.

7, for a variety of self-service vending machines, video games, juke-box OK karaoke, public telephone, mobile service station, bar management and reception system for all coins without pilot.

8, signal output mode: pulse, BYTE value, PC RS232 serial protocol, USB interface
