What The Universal Remote Control F21-E1B With Two Transmitters Is For
The F21-E1B-2TX is a single speed radio remote control set for overhead cranes, hoists, winches and mobile equipment, supplied as one receiver with two transmitters. It operates over a range of 100 to 150 metres and is rated IP65, allowing use in dusty, wet or outdoor environments without additional protection. The receiver accepts multiple voltages including DC12V, DC24V, AC36V, AC48V, AC110V, AC220V, AC380V and AC440V, so it can be installed directly into existing control panels without a transformer. Both transmitters use two AA batteries and feature a battery voltage warning that cuts power when low.
What You Get From This Unit
- Two transmitters allow multiple operators to work without swapping units
- Single speed control is simple to train and operate on standard lifting tasks
- IP65 rating protects both transmitter and receiver from dust and water ingress
- Receiver voltage matches your existing panel voltage, no extra transformer needed
- Over 4.3 billion unique ID codes prevent interference between nearby cranes
Universal Remote Control F21-E1B With Two Transmitters As Supplied
Where This Model Is Used
- Overhead cranes with single or double girders in fabrication or assembly shops
- Hoists and winches used in outdoor yards or wet environments
- Mobile equipment such as garden machines, tillers and sprayers
- Lifting operations where the operator needs to move freely around the load
- Retrofit of an existing pendant-controlled crane without rewiring the panel
Buyers This Model Suits
- Crane and hoist OEMs integrating controls into new machine builds
- Maintenance teams replacing a failed or damaged control set
- Equipment dealers stocking a multi-voltage remote control for different machines
- Traders sourcing a dual-transmitter set from China at low MOQ
What Goes Wrong Without It
- One operator must stay near the crane while the other moves the load
- Pendant cables snag on structures or wear out quickly in harsh conditions
- Existing panel runs DC24V but a standard 12V receiver would require a voltage converter
- Two cranes in the same bay respond to the same transmitter signal
- A single transmitter is lost or damaged and the machine cannot be operated
How The Unit Is Built
- Two transmitters and one receiver in a matched set
- 10 push buttons: 6 function buttons, 1 start, 1 stop, 1 emergency stop
- Crystal plug-in frequency generation across 80 channels at 0.2675 MHz spacing
- Control distance up to 150 m in open area
- Full sealed relay outputs rated 5 amperes
- Battery voltage warning cuts power when low
- Programmable button functions via computer software
- Safety magnetic key prevents unauthorized use
- IP65 protection on both transmitter and receiver
- Glass fibre housing for impact resistance

What The Housing And Contacts Are Made Of
- Glass fibre housing on transmitter and receiver for durability on industrial floors
- Sealed relay contacts rated 5 A to switch contactor coils directly without external relays
How This Unit Is Made
Step 1
Boards are assembled on the SMT line and soldered using automatic wave soldering
Step 2
Each set is paired to a unique ID code and channel before final assembly
Step 3
Receiver voltage is set according to order specification before testing
Step 4
All units are function tested for each motion and voltage before packing
Step 5
S/N and channel are printed on the back of both transmitters and receiver for future replacement
What Is Checked Before It Ships
- Raw materials and components inspected at entry point
- Step-by-step inspection during production on the 15 production lines
- Working process follows ISO9001:2008
- Each set is powered and tested for all functions before packaging
- 12 month warranty from delivery date
What Can Be Changed On Your Order
- Button functions can be programmed via computer software
- Button text and brand logo can be printed on OEM orders
- Two transmitters can be paired to one receiver for shared use
- Receiver voltage selected from the listed range at order time
- Magnetic safety key can be added for restricted access
How It Compares With The Alternatives
| Wired pendant control station | Radio removes trailing cable but adds battery replacement and receiver wiring; a pendant is cheaper and never needs pairing |
|---|---|
| F21-E1B-1TX single transmitter set | The 2TX version includes a second transmitter for immediate backup or shared use; if only one operator is needed, the 1TX is sufficient |
| F24 series double speed remote | Single speed is simpler to train on and sufficient for basic lifting; double speed allows fine control but adds complexity and cost |
Getting It Onto The Machine
- Confirm the control voltage on the crane panel before ordering the receiver
- Count the number of motions needed and ensure the set covers them with one spare
- Mount the receiver inside the control panel with the 1 m cable running to the contactor
- Watch the transmitter LED: slow flashing red means replace the two AA batteries
- Record the S/N and channel from the back of both transmitters and receiver for future replacement

Frequently Asked Questions
What is the minimum order quantity?
One set. A single sample is available for testing on your machine before placing a volume order.
How long is delivery?
Samples are ready in 2-4 days; small volume orders take about 7 days; shipping by FedEx or DHL takes 3-8 days door to door.
Which receiver voltage should I order?
Match the voltage on your crane’s control panel. The receiver supports DC12V, DC24V, AC36V, AC48V, AC110V, AC220V, AC380V and AC440V.
Can I get a replacement transmitter only?
Yes. Send the S/N and CH from your receiver and we will build a new transmitter on the same channel.
Will two cranes in the same bay interfere?
Each set uses one of over 4.3 billion unique ID codes and operates on 80 channels, so interference is prevented.
Can the button functions be changed?
Yes. Button functions can be programmed via computer software for OEM orders.
How is it packed?
