Small-shelf material management: e-paper audible-visual paperless picking (WE-PK25 + WE-TLED30)

Small shelves, bins, and spare cabinets still often use paper labels—dirty easily, slow to swap, and picking means flipping by hand. West Electronicssmall-shelf material management solutionuses two devices to keep “info on screen” and one-tap picking light:

• WE-TLED30: 2.9″ e-paper audible-visual electronic label
• WE-PK25: USB Bluetooth card-issuing gateway (stores about 1,000 e-paper label records on-device)

Customer pain points

1. Paper gets dirty or peels; text blurs
2. Manual re-labeling after SKU changes; updates lag
3. Picking means layer-by-layer search—worse with many locations
4. Book vs physical mismatch hurts inbound/outbound and inventory counts

System composition

A PC or mobile app handles search and call;WE-PK25 sends refresh and call commands over USB / Bluetooth;WE-TLED30 mounts on a location or bin, shows material info, and cues the pick point with sound and light.

WE-PK25 USB Bluetooth card-issuing gateway: USB + Bluetooth dual link; stores about 1,000 label records on-device; works with PC software and the MoPing ZhiFa app; call, issue, and manage labels.
