HF RFID Label HDL50 (55 × 18 mm, 1 KB)

What the HDL50 HF RFID label is

The HDL50 is a passive HF RFID label that works at 13.56 MHz and measures 55 × 18 mm. Its long, narrow shape is the reason to choose it: it sits along the edge of a file, the side of a carton or a slim device where a square or card-sized HF inlay would hang over. There is no battery; the reader's field powers the chip whenever the label is brought close to the antenna.

Chip and memory

Each label carries a 1 KB chip, offered as F08, D50 or M1. M1 is the common trade name for MIFARE Classic 1K, and F08 is a MIFARE Classic 1K-compatible chip. Most 13.56 MHz card readers handle this chip family, so the reader you already use for access or attendance cards is the first one to test with. Tell us which chip your software expects when you ask for a quote.

Where a slim HF label fits

• Files and records: one label per folder, scanned on a desktop reader at issue and return.
• Non-metal assets: plastic housings, wooden fixtures and boxed equipment.
• Samples and documents: bags, sleeves and boxes handled one at a time.

HF labels read at short range, and a standard HF antenna stuck directly on metal will not read reliably. For reading across a room or through a dock door, a UHF label is the better fit; our UHF vs HF vs LF guide explains the trade-off, or browse all HF RFID inlays and labels.
