The KR503E is ZKTeco's compact slave reader for 125 KHz proximity card systems. It sends a Wiegand credential signal to your access control panel -- no onboard decision-making, no keypad, no controller. That slim single-gang profile fits where a standard reader won't, which is the whole point.
Where it fits
Sized for thin mounting areas and standard single-gang electrical boxes, the KR503E works as an out-reader on panel-driven systems or as a paired secondary read point in multi-reader setups. Multiple 125 KHz proximity card formats are supported out of the box.
Key features
- Slave Wiegand output: passes credential data to the access control panel -- no standalone logic, no configuration overhead
