Automatic ESL Electronic Shelf Label | 2.13 Inch Digital Tag

E-ink ESL vs. Printed Paper Price Tag: An E-ink ESL presents price information electronically and can be updated over the 2.4GHz network, while a printed paper tag requires manual replacement for each price change. The trade-off is that the ESL requires a per-unit investment and a network infrastructure, while a paper tag has a very low per-unit cost but ongoing labor cost for updates. The 10-year battery work life listing and the 99.9% update success rate support the ESL in retail environments with frequent price changes.

2.4GHz Communication vs. Wired or Infrared Alternatives: The source lists a 2.4GHz communication protocol with a listed 99.9% update success rate and a 50-meter open-distance figure. A wired ESL system requires cabling to each shelf position, and an infrared system requires line-of-sight between the transmitter and the label. The trade-off is that 2.4GHz supports a wireless deployment without cabling, while the operating distance and any obstruction in the store layout should be mapped before the rollout.

Display Resolution Options: 250(H) x 122(V) vs. 212(H) x 104(V): The source lists two display resolution figures in separate specification blocks. The higher resolution supports finer text and clearer price display on the shelf edge, while the lower resolution may be sufficient for basic price digits. The trade-off is that higher resolution may affect the display refresh profile, so confirm the applicable figure and request a sample to verify readability before finalizing the order.

Scenario 1: Supermarket Chain Buyer — Price Display Rollout

A supermarket chain buyer sourcing electronic shelf labels for a price display rollout would typically confirm the display specifications and the communication range first. The source lists a 2.13 inch dot-matrix E-ink display with a viewable angle close to 180°, which supports shelf-edge readability from multiple positions. The buyer would confirm the 2.4GHz communication distance — within 30 meters standard with a 50-meter open-distance figure — against the store layout, and map the deployment to confirm whether additional gateways are needed. The 10-year battery work life listing reduces battery service frequency across a large installed base. The buyer would confirm the tiered lead time for the order volume and the dimensions customization minimum of 1,000 pieces if the program requires a custom label size. A pilot at the 3-day or 7-day tier supports a store-level test before a chain-wide deployment.

Scenario 2: Retail Operations Manager — Price Automation Program

A retail operations manager implementing a price automation program would typically evaluate the update success rate and the communication protocol first. The source lists a 99.9% update success rate over the 2.4GHz network, which is the figure that determines whether the automated price updates land reliably. The manager would confirm the display resolution — the source lists 250(H) x 122(V) and 212(H) x 104(V) in separate blocks — against the content that needs to display, such as price, unit price, and promotion text. The pixel colors of black, white, and red support multi-level pricing display. The operate temperature range of 0℃ to 50℃ covers indoor retail environments. The tiered lead time supports a phased rollout, with the 3-day window for a pilot and the 15-day window for a large deployment.

Scenario 3: Convenience Store Chain Procurement Officer — Shelf Edge Pricing

A convenience store chain procurement officer sourcing ESL for shelf edge pricing would typically confirm the form factor and the battery profile first. The 2.13 inch display size and the active area of 48.55 x 23.7 mm suit the compact shelf edge format of a convenience store. The 10-year battery work life listing and the waterproof non-replaceable battery reduce the need for on-site battery service, which matters for a chain with a large number of small-format stores. The officer would confirm the standard communication distance — within 30 meters — against the smaller store layout, and the 99.9% update success rate for the price management system. The tiered lead time supports a phased rollout starting with a pilot store.

Q: The source lists two display resolutions — how do I confirm which applies to my deployment?

A: The source lists 250(H) x 122(V) in one specification block and 212(H) x 104(V) in another. Confirm the applicable resolution for your specific ESL configuration with the supplier. The resolution affects the clarity of the price and text on the shelf edge, so confirm the applicable figure and request a sample to verify readability before the full deployment.

Q: How is the product packaged for shipping, and does the battery require special documentation?

A: The single package size is 36 x 30 x 6 cm with a gross weight of 2.500 kg — confirm with the supplier whether this reflects a single unit or a carton. The unit contains a waterproof non-replaceable battery, so battery transport documentation may be required. Confirm carrier acceptance and the required documentation with the supplier and a customs broker before shipment.

Q: What payment terms apply to a first order?

A: Payment terms are not specified on the source page. Standard practice for this category involves a T/T deposit with the balance due before shipment. Confirm the exact terms with the supplier before placing the order. Terms may vary based on order volume and customization depth.

Q: What is the communication distance in a real store, and how does it differ from the open-distance figure?

A: The source lists the communication distance as within 30 meters standard, with an open-distance figure of 50 meters. The open-distance figure typically reflects an unobstructed line-of-sight condition, while the standard 30-meter figure reflects the practical operating distance in a retail environment with shelving and fixtures. Confirm the applicable distance against your store layout before the rollout.
