Overview
The ZKTeco KR502 shares the 44 mm mullion width of the KR500 but in a deeper 26 mm housing, and it is the model in the family offered with either Wiegand or RS485 output. That choice is what usually decides it: RS485 lets several readers share one bus back to an InBio controller instead of running a separate Wiegand home-run per door.
- Reads 125 kHz ID cards (E versions) or 13.56 MHz MIFARE S50/S70 cards (M versions)
- Wiegand output (26-bit on E, 34-bit on M) or RS485, selected when ordering
- RS485 versions are intended for InBio160, InBio260 and InBio460 controllers
- Card read in 200 ms or less, at up to 10 cm on E versions and 5 cm on M versions
- Red and green LEDs with a beeper, plus external LED and buzzer control inputs
- Runs on DC 6-14V at 70 mA
One point to confirm at order stage: the KR502 is rated IP64, not the IP65 of the other readers in the family. It resists splashing rather than water jets, so for a fully exposed outdoor gate the KR500 or KR503 is the safer choice.
