Description
The Zkong Quantum Series is a family of electronic shelf labels built around an ultra-narrow bezel and a higher screen-to-body ratio. That puts more of the label to work as display, so a shelf edge carries more product information without a larger label.
The series covers six screen sizes, from 2.3 to 4.2 inches, in seven models. Every model uses a dot matrix EPD graphic screen managed from the ZKONG Cloud Platform, so prices and product data can be updated in real time from one place.
Designed for high-density shelves
Zkong positions the series for crowded retail shelves. Its slim integrated design improves installation flexibility, and customizable appearance options let the labels follow your store branding.
Display and wireless
Datasheets list a viewing angle of nearly 180º and 6 usable pages. Models use the 2.4-2.485GHz band with 128-bit AES encryption and over-the-air (OTA) updates. Six models list BLE 5.4; the ZKC25Q-E4 datasheet table lists BLE 5.1.
Power and compliance
Each label runs on 2 x CR2450 batteries (1200mAh). Battery life is up to 10 years at 2 updates per day (10 years in the ZKC25Q-E4 datasheet). Datasheets also list an RGB LED, NFC and CE, ROHS, FCC and SRRC certification.
