Ultrathin Table Indexer (DA)
Details:
The Sango DA series ultra thin cam indexer is a low profile rotary indexing drive for machines where height is the limiting factor. It has a raised center plate that stays stationary and a large hollow bore, both surrounded by a rotating output flange. That lets you mount fixed tooling in the middle while the dial carries parts from station to station.
A preloaded globoidal cam turns continuous motor input into accurate, self locking stops with no backlash at the dwell. Compact assembly and test machines get the rigidity of a full size indexer in a much slimmer frame.
How the Ultrathin Table Indexer (DA) Works
\. How It Works
A motor drives the input shaft at constant speed. The globoidal cam on that shaft engages rollers on the output turret. During the indexing portion of the cam, the turret rotates exactly one station. During the dwell portion, the cam profile clamps the rollers, so the output holds position mechanically. No brake, encoder or servo holding current is needed.
What sets the DA series apart is its layout. The center plate stays fixed, only the outer flange rotates, and a large hollow bore runs through the middle. The cam, roller turret and output flange are packed into a shorter housing. The drive fits under benchtop machines and compact cells where a standard table model would raise the working height.
Each unit is configured to your application. The station count, the index to dwell ratio and the motion curve (modified sine as standard) are set by the cam. Give us your stations, cycles per minute and dial load, and we will match the frame size.
Output structures available
Why machine builders specify it
Six characteristics that come from the cam profile rather than from control software.
Low Profile Housing
A shorter body than a standard table type indexer keeps the dial at a comfortable working height and frees space for tooling above and below the deck.
Fixed Center Plate
The raised center does not rotate. Sensors, cameras, pick and place risers or pneumatic manifolds can mount right on the axis while the outer flange indexes.
Large Hollow Bore
Air hoses, vacuum lines, signal cables and power can run through the center instead of around the dial. Wiring stays short, protected and untangled.
Zero Backlash at Dwell
Preloaded cam followers lock the output at every stop and hold position mechanically, with no brake, encoder or servo holding current.
High Load Capacity in a Slim Frame
The output flange carries heavy downward loads and radial forces from assembly, riveting, pressing and test operations without losing position.
Motor and Control Ready
Supplied alone or with a gear motor, servo, overload clutch, cam switch and mounting plate, so it installs as a complete drive package.
Models and load ratings
Four output styles across 31 frame sizes. Pick the output first, then size on torque and moment.

Six mounting orientations
The same frame can be bolted base-down, wall mounted or inverted, and the motor can sit above, behind or in line. Quote the code with your order so the unit ships with the oil level and breather set for that orientation.
Vertical Output Upward (Standard Dial Table)
Standard turntable orientation with dial plate mounted horizontally on top.
Vertical Output Downward (Inverted Mount)
Overhead hanging dial configuration for robotic cell ceilings.
Horizontal Output Right
Input shaft horizontal, output shaft extending horizontally to the right.
Horizontal Output Left
Input shaft horizontal, output shaft extending horizontally to the left.
Wall Mount Output Forward
Housing mounted against a vertical machine column, output extending forward.
Wall Mount Output Rearward
Housing mounted against machine frame, output facing inward.
