Single Axis Positioner Selection Guide

Introduction

A single axis positioner provides high‑precision rotation on one axis—Pan or Tilt. Compared with a traditional pan tilt unit, it offers simpler mechanical structure, higher stability, easier cabling, and lower system integration cost. ZIWIN's product line covers a full industrial‑grade load range from 3–300 kg, enabling both lightweight and heavy-duty applications.

Why Choose a Single Axis Positioner?

A single‑axis mechanism is ideal when your system requires rotation only in one direction. Benefits include:

- Reduced mechanical complexity

- Improved stability and long-term reliability

- Easier cable routing (especially when using slip rings)

- Cost efficiency for engineering and OEM applications

- Heavy-load capability within ZIWIN's 3–300 kg performance range

Key Terminology

• pan tilt unit — A dual-axis rotation platform (Pan + Tilt)

• pan rotate positioner — Horizontal‑axis rotation only

• tilt rotate positioner — Vertical‑axis tilt rotation only

• 3-300kg pan tilt unit — Heavy‑duty load classification referencing ZIWIN's supported range

• single axis positioner — A dedicated one‑axis rotation system

Technical Parameters

Important specification factors to evaluate:

- Load capacity: 3–300 kg (ZIWIN's full range)

- Rotation angle options: ±180°, 360° continuous rotation

- Rotation speed: low speed, medium speed, or high speed scanning

- Precision and repeatability: 0.1°  or  0.01°

- Control interfaces: RS485, RS422,RS232, Network interface, Wireless Remote

- Slip ring: required for uninterrupted 360° rotation

Selection Checklist

Conclusion

A single axis positioner is the most efficient solution for systems requiring reliable, precise one direction rotation. Compared with dual axis pan tilt units, it features simpler mechanics, easier integration, and enhanced long term stability. ZIWIN's 3–300 kg product range enables compatibility with lightweight optical sensors as well as heavy industrial or radar payloads. For scanning, tracking, automation, robotics, and measurement applications, a single axis positioner offers an optimal balance of performance, durability, and engineering value.
