Product Description

What this part is

Siko DA09S-4541-M, a mechanical digital position indicator from the Siko PositionLine range. Type: mechanical digital position indicator. Counter: 5 decades with fine reading. Hollow shaft: maximum ø 20 mm. Digit height: approximately 7 mm. Weight: 0.1 kg. The hollow shaft slides over a handwheel shaft or adjusting spindle, the counter is geared to shaft rotation, and the roller wheels read out axis position directly in the sight window.

Mechanical read-out

Digital here means discrete numerals rather than a needle on a dial. The numerals are printed on physical roller wheels turned by a gear train. The indicator runs entirely on shaft motion, so the reading stands where the shaft left it with the machine switched off. That suits hand-set stops, slitters, guide rails, press settings and machine-tool tailstocks, where an operator reads a number off the window directly.

Fine reading means the last decade is a vernier-style subdivision, giving resolution finer than one full digit step. The magnifying function in the sight window keeps the digits legible from an operator’s standing position.

Published specifications

Type: mechanical digital position indicator, Siko PositionLine range. Counter: 5 decades with fine reading. Digit height: approximately 7 mm. Readability: magnifying function in the sight window. Hollow shaft: maximum ø 20 mm. Display units: configurable for millimetres or inches. Housing: reinforced plastic, or zinc die-cast on the MCM housing option. Sight window: plastic standard, mineral glass optional. Sealing: axial seal, dustproof and splash-proof. Ambient temperature: 0 to 80 °C. Weight: 0.1 kg. Driving shaft: stainless steel available as an option. Scope of delivery: DA09S indicator.

Speed rating

Maximum shaft speed depends on the indication per revolution. 10 mm per revolution: 500 rpm continuous, 1500 rpm short-period. 15 mm: 500 rpm continuous, 1000 rpm short-period. 20 mm: 500 rpm continuous, 750 rpm short-period. 25 mm: 500 rpm continuous, 600 rpm short-period. 30 mm: 500 rpm. 40 mm: 375 rpm. 50 mm: 300 rpm. 60 mm: 250 rpm. 80 mm: 180 rpm. 100 mm: 150 rpm. Speeds above 500 rpm are rated for short periods only. These indicators are built for hand-turned and slow-adjustment duty.

What these specs mean in practice

Five decades with fine reading gives a long unambiguous travel range, so the reading does not roll over on a long spindle. The axial seal and the dustproof, splash-proof rating carry the unit on a shop floor with coolant mist and swarf. At 100 g in a slim housing it adds negligible mass behind the handwheel it sits on.

Decoding the order code

DA09S: the most-used size in the Siko PositionLine mechanical indicator range, slim design, 20 mm maximum hollow shaft. 4541-M: the configuration suffix, which sets mounting position, indication per revolution, decimal place and counting direction. Siko’s current long-form order key runs model, mounting position, indication after the first revolution, decimal place, counting direction, hollow shaft diameter, housing colour and material, seal, intermediate plate and clamping plate — for example DA09S-02-10-0-i-20-O-A-K-OAD-OZP-BP-ORP. Also written DA09S 4541 M, DA09S4541M and DA09S-4541M.

Quantity and configuration

Indicator only, sold individually. Companion Siko accessories carry their own part numbers: clamping plates KP09, KP09P and KPL09, and RH adapter sleeves — RH8, RH10, RH12, RH14 and RH18 — for spindles below 20 mm. Stainless steel driving shafts are VA8, VA10, VA14 and VA20.

Mounting data

Mounting position is set by the configuration code, so the window orientation follows the code the unit was built to.

Counting direction is fixed by the configuration: i counts up clockwise, e counts up anticlockwise.

Interchange guidance

Search forms: DA09S-4541-M, DA09S 4541 M, DA09S4541M, DA09S-4541M, DA09S. Related sizes in the Siko PositionLine mechanical range, each with its own hollow shaft diameter: DA02, DA04, DA08, DA10. Indication per revolution, decimal place and counting direction are set by the full configuration code, so the complete number identifies an exact match. Siko GmbH is a German manufacturer and the DA09S is a current catalogue product.
