KR502H is an outdoor IP67-rated tamper-resistant multi-technology proximity card reader capable of reading HID,
ZKAccess and Pyramid 125 kHz 26-bit proximity cards.
Due to its conveniently small mullion size, KR502H 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.
For the highest level of security KR502H has a built-in Wiegand-Out port which can be connected to most
any access control panel (including ZKAccess C3 and InBio door controllers).
