The GP90 type of proximity readers recommended to use at such installation where bigger reader distance needed and high security cards are not required. The reader transmit frequency is 125 kHz and belongs to the so called „non-conversational” system category, which means the communication between the reader and identification not encrypted. The reader works with the ASK type of EM4001 card and with the 64-bit Manchester encoded or compatible cards.
It has an automatic tuning feature that helps to minimize the negative reading-distortion effects of metal and other sources of noise in the reader's ambient.
Ideally, the reading distance may reach 90 cm, but in practice, a lower value is acceptable. In order to avoid faulty reading between two readers, a distance of three times the reading distance must be maintained.
The device has Magstripe AbaTrack2, Wiegand, RS-232 and RS-485 interfaces, allowing for extensive use. In Seawing system the AbaTrack2 interface is preferred.
The reader comes in black colour with a matte plastic cover, without power supply. It can also be fitted with a mounting column that facilitates the installation of the vehicle entry points.
