KJ353-F card reading substation product introduction
KJ353-F card reading substation is a kind of mine monitoring devices. Mine intrinsically safe equipment.Card reading sub-station is a main component of KJ353 type underground mine personnel management system, which adopts microprocessor as the core, can receive inflammations that send by multiple identification cards around at the same time, transfer the received information simultaneously to the ground host.
