What The Hoist Radio Remote Control F21-2S Is For
The F21-2S is a single speed hoist radio remote control with two function buttons, designed for chain hoists, electric carts, winches and mobile lifting equipment. It operates over a range of up to 100 metres using a matched transmitter and receiver pair, with 80 channels spaced at 0.2675 MHz and an operating frequency of 310.0325–331.165 MHz. Both units are rated IP65, making them suitable for dusty, wet or outdoor environments. The receiver is built to order for AC380V, 220V, 110V, 48V, 36V, 24V, 12V AC/DC or 380V/220V, so it can be installed directly into an existing control panel without a transformer.
What You Get From This Unit
- Single speed control simplifies operation for basic hoist lifting and lowering tasks
- IP65 protection ensures reliable operation in wet, dusty or outdoor environments
- Up to 100 metres range allows the operator to stand clear of the load and avoid hazards
- Receiver voltage built to order eliminates the need for a separate control transformer
- Over 4.3 billion unique ID codes prevent interference between nearby cranes or hoists
Where This Model Is Used
- Chain hoists in fabrication shops or warehouses where the operator needs to walk with the load
- Mobile lifting equipment and electric carts used in outdoor or dirty environments
- Winches and super winches on construction or mining sites exposed to rain and dust
- Retrofit of an existing chain hoist with a pendant control to a wireless remote system
- Maintenance teams replacing a failed or damaged pendant station without rewiring
Buyers This Model Suits
- Hoist and crane OEMs specifying controls for new equipment builds
- Equipment dealers stocking a control unit that fits multiple voltage standards
- Maintenance contractors replacing a worn or unsafe pendant control
- Traders sourcing a low MOQ remote control from China for quick delivery
What Goes Wrong Without It
- Operator must walk with the load while holding a pendant cable that drags on the floor or gets snagged
- Existing pendant control fails in wet or dusty conditions due to exposed connectors
- Control panel runs AC110V and a standard 12V receiver would require an extra transformer
- Two hoists in the same area respond to the same transmitter due to shared channel or code
- Pendant cable and plug fail repeatedly in a high-vibration or outdoor setting
How The Unit Is Built
- 2 function buttons for single speed lifting and lowering
- 1 START button and 1 mushroom-shaped emergency stop button
- Full sealed relay outputs rated 5 amperes for direct contactor switching
- Transmitter LED flashes slowly when voltage drops below 2.2 V and stops operation below 1.8 V
- Fault detection: rapid LED flashing indicates incorrect start sequence or jammed button
- Glass fibre-reinforced nylon-6 housing on both transmitter and receiver for impact resistance
- Operating temperature range from -35°C to +85°C, independent of battery tolerance

What The Housing And Contacts Are Made Of
- Glass fibre-reinforced nylon-6 housing for both transmitter and receiver to resist impact and environmental stress
- Sealed relay contacts rated 5 A to switch contactor coils directly without external relays
How This Unit Is Made
Step 1
Boards are populated on the SMT line and soldered using automatic wave soldering and soldering robots
Step 2
Transmitter and receiver are paired to a unique ID code and channel before assembly
Step 3
Each set is function tested against the ordered receiver voltage before packing
Step 4
S/N and channel are printed on the back of both units so a replacement can be matched later
What Is Checked Before It Ships
- Raw material through finished product is inspected step by step on the production line
- Working process follows ISO9001:2008
- Every set is powered up and each motion is checked before it leaves the line
- 12 month warranty from delivery
What Can Be Changed On Your Order
- Button text supplied as arrow tips or your own English labels
- Two transmitters paired to one receiver or a spare transmitter added to the set
- Receiver voltage selected from the listed range at order time
- Own brand and label printing accepted on OEM orders
How It Compares With The Alternatives
| Wired pendant control station | Radio removes the trailing cable but adds batteries to change and a receiver to wire in; a pendant is cheaper and never needs pairing |
|---|---|
| F21-4S with four buttons | The 2S is simpler and cheaper for basic lifting tasks; if more functions are needed, the 4S offers two additional buttons |
| Double speed remote controls | Single speed is sufficient for basic hoist operations; double speed adds complexity and cost without benefit for simple lift and lower |
Getting It Onto The Machine
- Confirm the control voltage on the existing hoist panel before ordering the receiver
- Count the motions the machine actually needs, then choose the button count with one spare
- Mount the receiver inside the panel with the 1 m cable running to the contactor terminals
- Watch the transmitter LED: slow red flashing means change the two batteries
- Record the S/N and channel from the back of both units so a lost transmitter can be replaced without changing the receiver

Frequently Asked Questions
What is the minimum order quantity?
One set. A single sample is available so you can test it on the machine before committing to volume.
How long is delivery?
Around 2-4 days for a sample order and about 7 days for a small volume order, then 3-8 days by FedEx or DHL.
Which receiver voltage should I order?
Match the control voltage on the hoist panel. The receiver is built for AC380V, 220V, 110V, 48V, 36V, 24V, 12V AC/DC or 380V/220V, so tell us the panel voltage with the order.
Can I get a replacement transmitter only?
Yes. Send the S/N and CH printed on the back of your receiver and we build a new transmitter on the same channel, so the receiver stays in place.
Will two hoists in the same bay interfere?
Each set is coded with one of over 4.3 billion unique ID codes and runs on 80 channels, so a transmitter only answers its own paired receiver.
Can the button text be changed?
Yes. Arrow tips are standard and your own English button text and brand can be printed on OEM orders.
How is it packed?
One set per box at 18.7 x 8.6 x 7.9 cm, six sets per carton at 38.5 x 28.5 x 25.5 cm.
