Compact electronic position indicator

December 2016 Sensors & Transducers

The new AP05 position indicator is the most compact of all the bus-compatible position indicators from Siko. As the successor to the AP04, the AP05 offers the same space-saving dimensions, as well as being attachment compatible allowing quick and easy attainment of the target position. A significant new element of the AP05 – an inverted, backlit LCD display – has been integrated for this reason. The lighting ensures that the values for the target and actual position are maximally legible, even in low light conditions.

Intuitive operation

Along with the LCD directional arrow, the AP05 position indicator also offers intuitive user guidance via the right and left status LEDs, both integrated into the case and in two colours. These not only signal positional status (InPos or OutPos) but also simultaneously indicate the required rotational direction.

Increased robustness

The AP05’s mechanical robustness has also been significantly improved with the help of a carbon fibre reinforced case and protective cover for the display. Thus, the indicator is also usable in areas where mechanical strain on the connector plug and case or impacts to the display cannot be ruled out. Because the connector plug is also available with an optional cable outlet, the position indicator can be flexibly deployed in constrained spaces.

Flexible network integration

The bus compatible AP05 position indicator can be equipped with either an RS-485 or a CAN interface. The network integration is also fully compatible with the AP04 predecessor, as well as with further bus-compatible Siko position indicators in the current generation – AP10, AP10S, and AP10T. With the use of additional interface converters, the AP05 can be integrated into a wide range of fieldbus and Ethernet networks including Profibus-DP, Profinet I/O, Ethernet/IP, EtherCAT, and Powerlink.

As with all Siko position indicators, the AP05 also features a hollow shaft, guaranteeing the easiest assembly possible for standard adjustable axles. Despite its ultra-compact design, it can accommodate spindle shafts up to 20 mm in diameter. With regard to the size and clearance of the torque reaction support, it also features attachment compatibility with not only the AP04 but also with the DA04 mechanical position indicator. Thus, the machine’s frame can be switched from manual adjustment with mechanical position indicator to monitored format adjustment with the AP05 – no changes necessary. Due to the high degree of protection afforded by IP65 and the use of stainless steel, the AP05 is well suited to applications in the fields of food production, drinks manufacturing, or pharmaceuticals.
