Zkong Shield Series Electronic Shelf Labels (1.54 to 3.7 inch Durable Retail EPD ESL)

Description

The Zkong Shield Series is a set of electronic shelf labels built for busy retail floors. Its protective casing guards against dust, moisture and the wear of frequent handling, so the screen stays legible for longer. The e-ink display keeps prices readable at the shelf edge and draws power only when its content changes.

The series covers five screen sizes, from 1.54 to 3.7 inches, in seven models. Two are Freezer models, ZK21SF and ZK26SF, rated for -25~25℃ with a Black/White screen. The other five use Black/White/Red/Yellow pixels and are rated for 0~40℃. All models connect to a central management system for remote price updates.

Built for busy retail environments

The series page positions the labels for supermarkets, pharmacies, cosmetics counters, electronics stores, buffet areas and fresh food sections. The protective casing helps a label stay in service longer, and real-time updates let promotions and competitor price matches reach the shelf quickly.

Display, wireless and security

Datasheets for all seven models list an EPD screen with a viewing angle of nearly 180º and 6 usable pages. Every model uses 2.4-2.485GHz BLE 5.4 with 128-bit AES encryption and over-the-air (OTA) updates, and every datasheet lists NFC. The Freezer models ZK21SF and ZK26SF are Black/White only, described as black and paper white.

Power, temperature and certification

Four standard models run on 2 x CR2450 batteries (1200mAh) with up to 10 years at 2 updates per day. The ZKC15S uses 1 x CR2450 (600mAh) with the same rating. The Freezer models use a lithium pouch cell (1000mAh) rated at 5 years at 2 updates per day. Datasheets list CE, ROHS and FCC certification for every model.
