PSAG series motorized goniometers
PSAG series motorized goniometers are made of hard black anodic-oxidation aluminum alloy which presents excellent appearance. Fine precise worm gear/worm and arc V-shaped guides are key parts of guiding mechanism. This combination guarantees higher strength, higher load capability and better durability.
Features
- Fine grinding worm gear/worm offers higher positioning accuracy
- Arc V-shaped guide offers higher loading capability
- Standard two-phase stepping motors are stable and reliable, with self-lock function
