Description
The Zkong Blade Series is a family of ultra-thin electronic shelf labels for shelves where a slim profile and a clear screen both matter. Its main design idea is seamless integration: a slim body that does not block the product display, with a high-resolution e-ink screen for prices and promotions.
The series lists 21 models across 14 screen sizes, from 1.8 to 10.2 inches, from small shelf-edge labels to large display tags. Most use a Black/White/Red/Yellow dot matrix EPD screen; several -J and -JK models are black and white.
Slim profile for crowded shelves
Zkong positions the series for stores where the look of the shelf matters as much as the information on it. The slim body blends into the shelving, and the e-ink screen needs no backlight, which keeps the label thin and light.
Display and wireless
Models use the 2.4-2.485GHz band with 128-bit AES encryption and over-the-air (OTA) updates. Most datasheets list BLE 5.4; the ZKC75B-J, ZKC75B-JK and ZK58B-J datasheets list BLE 5.1.
Battery, temperature and certification
Battery capacity runs from 600mAh on the ZKC18B to 7200mAh on the ZKC75B-J, ZKC75B-JK and ZK58B-J, which use 12 coin cells each. Most models are rated up to 10 years at 2 updates per day. The datasheets list CE, ROHS and FCC certification, with SRRC also on the ZKC22B. Operating temperature is 0~40℃ on every datasheet except the ZK58B-J, which lists 0~50℃.
