Wireless transmitter-receiver set · 2-button single-step control · 110/220 VAC receiver · Entek D21-2S-2TX/RX-2
Industrial wireless remote control set with 2-button single-step operation and a 110/220 VAC receiver for crane, lift, conveyor, winch, door, and machinery control. The D21 series is commonly used where simple up/down or open/close control is needed, with typical wireless range of approximately 200 to 300 ft (61 to 91 m) depending on site conditions.
What this product is for
This is a matched industrial wireless transmitter-receiver set for simple 2-button, single-step machine control. It is used where operators need basic remote command functions such as up/down, open/close, or forward/reverse on compatible equipment.
Use for
Use for cranes, hoists, mobile lifts, winches, tailgates, conveyors, tow trucks, doors, machinery, and some agricultural equipment where a compact radio remote is suitable. It is commonly selected for straightforward motion control with an AC-powered receiver.
Avoid for
Avoid for applications that require inherent failsafe redundancy or where injury or equipment damage could result from improper operation or RF malfunction. Confirm suitability with the machine control design, local code, and site safety requirements before specifying.
Best for
Best for industrial and light commercial equipment needing 2-button remote control, single-speed output logic, and a receiver powered from 110/220 VAC. This format suits buyers replacing an existing D21 setup or standardizing on Entek D21 controls across similar equipment.
Installed in
Typically installed on control panels, machinery enclosures, lifting equipment, conveyor systems, service bodies, and powered access equipment. Actual mounting method, wiring, and enclosure protection depend on the machine builder or retrofit design.
Why this product exists
This set provides a practical way to add or replace wireless machine control without moving to a more complex multi-function pendant. It is intended for simple control tasks where fewer buttons, single-step operation, and an AC receiver are the main buying requirements.
Compared with similar products
Compared with larger multi-button radio remotes, this 2-button version is better suited to basic control schemes and simpler operator training. Compared with hardwired pendants, a wireless set can improve operator positioning and visibility around moving equipment. Typical wireless range is approximately 200 to 300 ft (61 to 91 m), but actual performance depends on installation conditions, interference, obstructions, and site layout.
