Zebra® RFD40 UHF RFID Sled
UHF RFID sled for Zebra mobile computers, 1300+ tag reads per second, IP54 sealed

RFD40
The RFD40 is a Zebra® UHF RFID sled supplied by JNXRFID to the manufacturer's published specification. It carries the UHF radio, the antenna and the trigger; the screen, keypad and barcode scanner stay on the host mobile computer it mounts to.
- 1,300+ tags/sec
- Read range up to 40 ft (12 m)
- IP54
- 7000 mAh battery
Key Features
- RFID performance
- 1,300+ tag reads per second, which is what cuts the time a cycle count takes when the population is large.
- Read range
- Maximum 40 ft (12 m) on the standard model. The manufacturer publishes a longer-range variant on the same page at a maximum of 80 ft (24 m), so state which one is being quoted.
- Where the radio is
- This is a sled, not a sealed handheld. The UHF radio is in the sled; the display, keypad and scanner stay on the host mobile computer it mounts to.
- Host connection
- Connects through the eConnex direct connection to current and future Zebra mobile computers, and wirelessly over Bluetooth 5.3 on the variants that carry it.
- Batch memory
- Stores large tag reads offline, so a count can continue where there is no constant network connection.
- Battery
- 7000 mAh PowerPrecision+ battery with a quick-release function, so a spare pack can be swapped without powering down.
- Handling
- Tri-function, user-programmable trigger, with a 5 ft (1.5 m) drop specification to concrete.

What to check before you specify a handheld?
The most common mistake in an RFID handheld quote is assuming the radio is in the handheld. On this family it is in the sled, and host computers are also sold without any UHF radio. The answers below cover what to confirm first.
Is the UHF radio inside the handheld or in the RFD40?
In the RFD40. It is a sled: the UHF radio, the antenna and the trigger are in the sled, and the screen, keypad and barcode scanner stay on the host mobile computer it mounts to. Zebra also sells otherwise similar mobile computers with no UHF radio at all, so which part carries the radio should be confirmed before a handheld is quoted for an RFID job.
How fast does it read?
1,300+ tag reads per second. That figure is what makes a cycle count over a large population finish inside the shift rather than after it.
How far does it read?
Maximum 40 ft (12 m) on the standard model. The manufacturer publishes a longer-range variant on the same page at a maximum of 80 ft (24 m), so the range of the specific unit being quoted should be confirmed rather than assumed from the family name.
Which mobile computers does it fit?
It connects through the eConnex direct connection to current and future Zebra mobile computers, and wirelessly over Bluetooth 5.3 on variants that carry it. The host adapter required depends on the host model, so the host and the sled have to be quoted together.
Does it need a network connection while counting?
Not continuously. It stores large tag reads offline, so a count continues where there is no constant connectivity and is uploaded afterwards.
Can the battery be changed mid-shift?
Yes. The battery is a 7000 mAh PowerPrecision+ pack with a quick-release function, so a spare pack swaps in without powering the unit down.
