Wireless crane remote control | 4 buttons + START/STOP | 1 speed | 433 MHz | 100–240 V AC | modular receiver | AK-C211008

433 MHz wireless control set with modular receiver – 4 buttons + START/STOP

AK-C211008 is a transmitter and modular radio receiver for simple hoisting and drive mechanisms. When a button is pressed, the transmitter sends the command at 433 MHz, the receiver relay closes the channel, and the channel energises a contactor coil. The motor is switched by the contactor, not by the receiver.

• Separate START and STOP – the system stays inactive until the operator deliberately enables it
• 4 direction buttons – for two axes, e.g. hoist and travel
• 433 MHz link – EU SRD band widely used in industrial equipment
• 100–240 V AC supply – connects directly to a 230 V AC control circuit
• Module with terminals – quick to wire in a panel or enclosure
• External antenna – can be routed outside the panel so metal does not weaken the signal

• ES-E1738-315B – 315 MHz, set with 2 transmitters with 2 direction buttons each, channel load up to 4 A
• ES-ML-K2 – 868 MHz, receiver in an IP66 housing, 230 V AC – no separate enclosure needed
• ES-F21-E1-TX – 6 buttons + START/STOP, receiver in an IP65 housing, 24–440 V AC/DC, up to 100 m

• Gate, barrier and damper drives
• Small electric winches
• Goods and material hoists
• Simple workshop hoists – with an additional safety circuit
• Sliding platforms and auxiliary conveyors

• The receiver relays switch contactor coils only – never pass motor current through them.
• Mount the receiver in an IP enclosure or panel: do not leave the open board exposed to moisture, dust or touch.
• Wire the STOP channel into the main contactor KM0 circuit; loss of the radio link must stop the mechanism (EN 60204-32) – test this before work.
• Limit switches (SQ) and NC interlocking of opposite directions stay in the circuit.
• For heavy cranes and loads over people – only with an additional safety circuit, or choose an industrial remote with a housing.
• Before installation or repair – LOTO on the main isolator.

Quick selection guide

Check before ordering:

• Does the contactor coil voltage match the 100–240 V AC receiver supply?
• Do you have an IP enclosure or panel space for the receiver?
• How many directions and speeds do you need: 4 buttons control 2 axes at one speed.
