PositionLine Mechanical Indicators
How it works
| SIKO's mechanical indicators use a system of internal gears to track position.
The gears are connected to the indicator's hollow shaft bore. When the shaft is rotated, the digital count on the display is increased or decreased depending on the direction of the rotation. SIKO indicators can "count" from 0-4 up to 0-200 in one complete turn. Many different counts are available |
 |
Before mounting a SIKO mechanical indicator, a hole must be drilled for the torque pin.1
1 Drilling diameter and depth are detailed in the product data sheets.
 |
| A torque pin is fixed to the back of every SIKO indicator. The torque pin will fit into the pre-drilled hole on the machine to prevent the indicator from slipping when the shaft turns. 
Two torque pin types are available: a standard "plain" pin for H7 tolerance (low torque), or an umbrella pin for higher torque tolerance and hole sizes.The umbrella pin is not available for DA08 |
To mount the indicator, simply slide it onto the machine shaft, fitting the torque pin into the pre-drilled hole. A set screw will fasten the indicator to the shaft.
SIKO mechanical indicators can fit shafts with diameters from 6mm (~0.25") to 35mm (~1.375")

Additional options for mechanical indicators
A clamping plate can be used to keep the shaft from rotating due to minor vibration. |
Most indicators can be fitted with a rubber axial seal to keep moisture and debris out of the indicator.
Show me indicators that have optional axial seals. |
Two indicators are available with completely-sealed water-proof housings.
