Position indicator

For linear adjustments in production machines

The Siko AP20S position indicator in combination with the MS500H linear magnetic sensor with external connection. It is intended to detect the position of linear guides and slide adjustments in machines.

The operator can see the target and actual position directly at the adjustment position, and this information is also transferred to the main machine control system. It is therefore suitable in production machines of all sorts: e.g. packing machines, woodworking machines, and printing machines.

In addition to the CAN and CANopen data interfaces, others are also integrated. Integration into current control systems from various manufacturers is therefore possible directly and without any other accessories, said the company. In comparison to a converter solution, the variety of components is reduced, as is the space required in the machine. The result is loss-free communication across the board between control and sensor level, which is necessary, in particular, for systems with a large number of sensors and long cable lengths. For this purpose, the AP20S has two M12 (D-coded) connectors for a bus line design that protects the cable, meaning that star-shaped wiring to the control system is no longer essential.

The AP20S addresses this by using the extensive diagnostic options of network technologies and an electronic type plate, which serves to identify the device type, serial number, and software version. Corresponding integration aids such as function modules, libraries, and add-on instructions enable commissioning and lead to application programming.

The AP20S, in conjunction with the MS500H external linear magnetic sensor, combines the functionality of a linear absolute value encoder with a position indicator, and yet it can be fitted to the machine in an area no bigger than a credit card (48 mm x 88 mm x 61mm). The MS500H sensor can also be integrated with dimensions of just 27 mm x 15 mm x 8 mm. Thus, the positioning solution is suited for monitored size changeovers even in machines and systems where space is limited. With protection class IP65 and IP53 and the use of stainless steel, the product is also suitable for applications in the food industry, drinks manufacturing, and the pharmaceutical sector.

The option of displaying the target and actual position directly on the adjustment position increases convenience for the machine operator, said the company. Siko opts for an inverted, backlit LCD for the AP20S to make this information easy to read, even in unfavorable lighting conditions. The position indicator also offers intuitive user guidance with the two-colored LEDs integrated on the right and left. In addition to the positioner status (Inpos or Outpos), the LEDs indicate the direction of rotation required to reach the intended target position.
