Three dimensions matter when choosing an industrial remote control: speed control, keypad size and protection rating.

1. Single vs Dual vs Multi-Speed

• Single-speed: start/stop control for simple lifting
• Dual-speed: slow precise positioning plus fast travel, most common for cranes
• Multi-speed / VFD: smooth speed control for precise work

2. Keypad Size

Select by the number of motions: 6 keys for single hook, 10-12 keys for double hook, leaving 1-2 spare keys.

3. Protection Rating

IP54 for indoor, IP65 or higher recommended for outdoor and dusty environments, IP67 for ports and mines.
