Features:Intelligent LED display reminder function, making operation intelligent and simple. Plastic panel, special plastic for car bumper, durable. High-performance CPU processing system, integral accuracy rate of 100%. Anti-interference isolation circuit design, greatly improving product stability and durability. With human mechanics design, it is quick and easy to return coins. Support hot plug and pull, plug and play, no need to power off operation, installation is more convenient. Anti-large coins adjust the metal sheet, you can manually adjust the accuracy of the coin size. The spring elasticity is optimized, and the coin clutch state can be quickly restored after the fault is cleared, ensuring smooth coin-operated operation. The opening angle is optimized to prevent the opening angle from being too large, resulting in the disconnection of the back cover and the coin channel. The cover can be opened 130, the card is worry-free, and the cleaning is convenient. VR: Precision adjustment knob, and it can be adjusted the precision manually. SW1: COIN polarity switch, adjust output polarity, normally open (NO) / normally closed (NC).
