Things You Should Know About Coin Acceptors

Coin acceptor

Before you buy a Coin acceptor, there are several things you should know about it. For example, the diameter and thickness of a coin are crucial factors. Then, you should look for its pulses. If they’re too fast or too slow, you shouldn’t buy it. Also, consider the price and size. If you’re going to use it frequently, you should look for one that’s able to withstand the high demand.

Coupling between coils

Depending on the material of the coin, the coupling between coils on a coin acceptor can change. When a coin is introduced to the coin acceptor, the coupling between coils changes depending on the diameter, transit speed, and material. Once a coin is recognized, a solenoid-driven flap is moved out of the way to store it. Otherwise, it falls out of the coin return slot.

The sensing coil unit measures the diameter of a coin, based on the impedance of the coin as it passes. The coil unit generates a pulse whose width depends on the diameter of the coin. This pulse is then converted to a digital signal, and the parameters of the coin are stored in a memory. Coupling between coils on coin acceptors is a critical component in detecting counterfeit coins.

The coin acceptor sensor comprises an inductor for inductive coupling and two capacitors with substantially equal values. The detector is connected to the output of the coin acceptor by a feedback loop. The sensor coil and inductor are then connected to each other sequentially using a multiplexer. The multiplexer feeds successive samples of the amplitude deviation to a microcontroller.


The coin acceptor uses logic signal pulses to decode the coin value. Its firmware must be developed properly to prevent double or missed detection. These applications involve monetary transactions and any bugs in the system can create serious issues with customers or clients. Here are some tips to ensure that your coin acceptor is working correctly and efficiently. Weigh the advantages and disadvantages of each model to find the one that is the most suitable for your needs.

The main difference between the two models is that the one with six slots can accept more than just four coins. This allows it to accept six different kinds of coins. It can be used for arcade cabinets and charge admission to a house. If you have a creative idea, why not monetize it? You can buy this unit for around $600. It comes with full instructions. In addition to that, it can be used in various settings.

The coin acceptor works by validating the coin. Then the host controller extracts the coin value and assigns it to the coin. These devices use a proprietary protocol to communicate with each other, detecting logic levels on multiple pins. But this type of technology still has limitations. Pulses for coin acceptors are limited in their usefulness. You can find them at any retail store, convenience store, or other retail location.


The size of coin acceptors can vary considerably. Some accept coins in multiple directions and offer many sizes. They are also available with a faceplate for mounting directly onto the surface. These can range in size and material. If you intend to use the coin acceptor in a business setting, you should determine which type is suitable for your location. Considering the size of your business, you should choose a coin acceptor that is large enough for the space available and has a small footprint.

There are two general sizes of coin acceptors. The smaller 3.5-inch coin acceptor is an excellent choice when space is at a premium. While this model is compact, it provides excellent reliability for businesses that need the coin-sorting capability in a small area. Coins will generally fall into the cash box if one is not supplied. Some models offer optional sorting methods. The larger 5” diameter version offers additional routing options and can sort coins in up to four or six directions. It is usually used in conjunction with coin hoppers.


A coin acceptor is a machine that allows users to deposit coins. They can choose to use either real or fake coins. They can also be programmed to accept various types of coins. The weight of the coin acceptor is an important consideration, as it affects its ability to handle different kinds of coins. However, you should not make the mistake of thinking that a large coin acceptor is always the best choice. Instead, consider the weight of the coin acceptor before purchasing it.

The coin acceptor comprises two rods, one mounted in a support 50, and the other fixed to the door 40 of the vending machine. The rods have generally spherical ends 52. Each rod is attached to a socket 54 that allows it to move freely in a horizontal plane and pivot upwards and downwards. A hinge 42 joins the two pieces together, and the door opens and closes.


One embodiment of a mass coin acceptor is illustrated in FIG. 2. This embodiment of the coin acceptor comprises a main body section 122 of molded plastic with opposed side walls. The transverse wall 128 extends between the side walls and merges with a mid-width portion thereof. In addition, guide walls 130 and 132 project outwardly from the transverse wall and define a coin chute, with the confronting coin path defining surfaces 12 and 14 defined by the wall.

Another type of mass coin acceptor incorporates a light emitting and sensing arrangement for determining the mass of a coin. It also examines a coin’s size and reflectivity, and is capable of detecting if the coin has a central opening. When this coin is detected, the device generates a timing or pulse signal that is then used to activate an electronic counting circuit. An electrical count of pulses indicates that the coin is valid.

Another embodiment of the mass coin acceptor incorporates a light responsive detector which serves as an open-circuit element. The light source and the sensor unit are typically located on opposite sides of the coin track. This complex mechanical configuration increases cost and difficulty of manufacture. A further embodiment of the mass coin acceptor is described in FIG. 4. It has a switch that is triggered when a coin is dropped through the accept side of the machine.


A coin acceptor is a device that can accept coins. Coins with a specific size and shape will pulse through the device for 20-60 milliseconds to indicate whether they are valid. Then, when the coin is dropped through the acceptor, it will fall into a reject chute. The device also features a cable that directs coins to a suitable location. To determine the value of a coin, you will need to know its size, thickness, and diameter.

Some coin acceptors also feature sensors to measure the diameter, thickness, and fall time of coins. These sensors are fully programmable. Simply select a coin profile, insert a sample coin, and set the value. The acceptor then reports the value of each coin to a serial output. The baud rate of the unit is adjustable. The user can also change the amount of precision and resolution desired. The value of a coin acceptor is a good indicator for determining how much it is worth.
