Siko DA04 Digital Position Indicator

Siko DA04 Digital Position Indicator is a mechanical digital display, or DA for short, SIKO offers an original and sophisticated product line.

Siko DA04 Digital Position Indicator is a mechanical digital display, or DA for short, SIKO offers an original and sophisticated product line. The highly customizable, functional concept is known the world over, and its interplay of variable gear ratios and counters that can be configured on a modular basis is unique. The position indicators from the DA range constitute a further development of analog handwheel technology. However, the “Nonius’’, a type of precision measuring gage on handwheel indicators, can only display the values of one spindle revolution. But what if several revolutions have to be documented?

This calls for a technology that is functional and robust and has two special features:

  • a display with several digits, including a decimal point and a fine meter reader for optimum precision of readings
  • a gear that, order-picked according to customer wishes, translates adjacent axle revolutions into a display scale that can be quickly understood.

Mechanical digital position indicators make format adjustments child’s play

With the original counters from SIKO, position values can be checked reliably directly on the axle or spindle. Simply plug onto the shaft, lock, and done – thanks to sophisticated technology, the small “indicators in orange“are in tireless use as spindle position indicators worldwide a million times.

Siko DA04 Position indicators from SIKO are being used in all production environments across most branches of industry, as guiding elements, material stops or tools must be positioned or aligned precisely and reliably on nearly all machines or units.

Mechanical-digital position indicators are very versatile

The digital position indicators are ideal for monitoring roller adjustment on sheet metal bending machines. The solid cast design of the SIKO position indicators withstands extreme mechanical influences under tough conditions such as those on round sheet polishing machines, ensuring exact manufacturing. They are used with particular versatility in woodworking. In this area, several work steps are often performed on a single machine, with plates cut and milled and edges glued and polished. SIKO counters are ideal adjustment aids in the metal, plastic and woodworking industries.
