KR500E is a series of outdoor IP65-rated proximity card readers designed to read only ZKAccess-supplied proximity cards.

Due to its conveniently small mullion size, KR500E is the ideal card access solution for any metal doors with thin frames, parking gates, fences, turnstiles or any security device having a narrow mounting surface. KR503E is designed for single-gang mounting.

KR500E Series has a built-in Wiegand-Out port which can be connected to most any access control panel (including ZKAccess C3 and InBio door controllers).
