Wiegand Access Control Panel Guide
What is a Wiegand device?
Wiegand equipment refers to a type of electronic equipment commonly used in access control systems
Wiegand devices consist of a card or fob embedded with a Wiegand wire or coil. Wires are usually made of stainless steel and surrounded by insulation. When a Wiegand device is brought close to a Wiegand reader, the wire interacts with the reader's magnetic field, generating an electrical pulse. The pulse is then interpreted by an access control system, allowing or denying access based on information encoded in the device.
Wiegand devices are known for their reliability, durability, and resistance to tampering, making them popular in security systems.
These devices follow a similar basic function to what we see in bank cards. However, the bank card will use a strip of ferromagnetic material instead of wiring. The wiring in the Wiegand equipment made the system more difficult to replicate.
In summary, a Wiegand device is a card and any type of data reader that operates on a special wired communication system. These need to be used with Wiegand sensors to work.
What is 26-bit Wiegand?
A complete Wiegand system includes the device to hold the data as well as the reader. A proprietary wired communication format between the reader and the access control technology is key here. You'll also come across the term "26-bit Wiegand" when dealing with these devices.
26 bits is the encoding used by the reader and proximity credentials. Basically, this is the protocol for the data found on your Wiegand device. 26-bit is the industry standard format for open coding of access control systems.
Data encoded using this format provides a large number of possible facility codes and unique card numbers. This helps to ensure that your data is more secure within the Wiegand system.
What is the Wiegand Effect?
The Wiegand effect refers to the behavior of the magnetic field from the specially designed wiring of the above system. This effect occurs when a Wiegand device comes into contact with a Wiegand reader.
It produces nonlinear magnetic effects in this specially annealed wire. The type of wire used in the Wiegand system is important here. The wire is a low carbon Vicat alloy wire. It is a ferromagnetic alloy of cobalt, iron, and vanadium.
For example, the Wiegand effect occurs when you use an ID card or access control device to open a security door. It's this magnetic effect between the wiring and the card reader that makes your device work.
