Motorized head YJT-EFPTZDUSO4DA series

Product overview
The YJT-EFPTZDUSO4DA series is a heavy-duty pan-tilt head for precision positioning of camera and sensor payloads. The 20K variant features a dual-side load design, closed-loop servo motor with harmonic drive and magnetic encoder, and industrial-grade protections for continuous operation in harsh environments.

Key features

• Dual-side load: left and right each support half the total payload for balanced mounting (20 kg model).
• High-precision motion: closed-loop servo with harmonic drive and magnetic encoder — repeat accuracy Pan ±0.005°, Tilt ±0.01°.
• Wide motion range and adjustable speed: continuous pan 0°–360°, tilt -90°–90°; pan speed up to 40–60°/s, tilt up to 20–40°/s (model-dependent).
• Robust communication: RS422 interface, Pelco-D protocol (9600 baud), supports direct cable transmission up to 1000 Mbps.
• Environmental resilience: IP67, device-level lightning protection (power 4000V, signal 2000V), operating temperature -40°C to +70°C.
• Customizable: angle and speed settings, wiring and hardware/software options on request.

Ideal applications

• Industrial surveillance and monitoring
• Aerospace and military camera platforms
• Remote sensing and measurement systems
• Heavy-load precision positioning
• Automation in harsh environments
