Detailed
2.13inch Low Temperature 2.4G Electronic Price Label in Cold Environment
The 2.13 inch low temperature electronic shelf label is specifically designed for challenging retail environments where standard ESLs cannot operate reliably. It uses low power e-ink technology, making it easy to highlight promotional prices, warnings and product information. It has a high resolution with 250x122, the label delivers sharp and clear visuals for text, barcodes, and images.
Engineered for cold-chain applications, this ESL operates stably in temperatures as low as -25°C, making it ideal for refrigerated and frozen environments such as supermarkets, fresh food zones, and cold storage warehouses.
With IP68 protection, the 2.13 inch electronic price tag is fully resistant to water and dust, ensuring long-term durability even in humid, wet, or frequently cleaned environments. Combined with 2.4GHz wireless communication, it supports real-time data updates within a range of up to 30 meters indoors (up to 50 meters in open areas), enabling efficient and centralized price management.

● Extreme Low-Temperature Performance
Designed for cold environments, this ESL operates reliably in temperatures ranging from -25°C to 10°C, making it ideal for freezers, cold-chain logistics, and fresh food retail applications where conventional labels fail.
● IP68 Waterproof & Dustproof Protection
Built with a fully sealed industrial-grade enclosure, the label is IP68-rated, ensuring protection against water immersion, dust, and harsh cleaning processes—perfect for humid or washdown environments.
● Reduce Operational Costs
Electronic shelf labels eliminate the need for frequent paper price replacements. Prices can be updated remotely through the management system, helping retailers reduce labor costs and avoid pricing inconsistencies between shelves and POS systems.
● Robust Communication Range
Operating in the 2.4~2.48GHz frequency band, the label offers a communication distance of up to 30 meters indoors and up to 50 meters in open areas.
● Ultra-Low Power Consumption
E-paper technology only consumes power during screen refresh, significantly reducing energy usage and extending battery life for long-term operation.

How do 2.4G Electronic Shelf Labels Work?
Electronic shelf labels (ESL) use wireless communication technology to connect digital price tags with a central management system. When a retailer updates a product price in the system, the information is automatically transmitted to the corresponding electronic label through a base station.
First, the ESL label management software on the server processes the information for each item and packages it into data packets containing pricing and product details.
Next, the software transmits these data packets to the base station via a 2.4 GHz wireless signal. After receiving the packets, the base station forwards them to the corresponding electronic shelf labels (ESLs) to update the price displayed on the screen. Each ESL has a unique identification code, allowing it to receive and display the specific information associated with the corresponding product. Data can be sent either to all label devices simultaneously or to selected labels individually. This process allows stores to update thousands of prices simultaneously without manual replacement of paper tags.
