Ultra-compact magnetic sensor for machine construction

SIKO GmbH: With its MSC sensor family, SIKO GmbH presents the latest stage of development in ultra-compact magnetic sensors for industry as well as machine and plant construction. Common applications for SIKO’s latest compact sensors include linear actuators, stop adjustment for saws, and even measurement of the tracking of solar plants.

Path, angle and rotational speed measurement tasks
The sensor measures paths, angles or rotational speeds – contactless and wear-free – in conjunction with the associated magnetic tapes or magnetic rings. The sensor reads the magnetic code of the magnetic tape or magnetic ring incrementally. This information is converted into digital square-wave signals and sent to the downstream electronics.

Clever detailed solutions
The SIKO magnetic sensor MSC500 constitutes a significant further development of the previous MagLine magnetic sensors, in terms of their performance and integrated technology. The sensor includes, for example, a clever, multicolored status LED that considerably facilitates commissioning and functional checking for the user. For example, the correct distance between the magnetic band or magnetic ring is monitored visually. If the reading distance between sensor and magnetic tape / magnetic ring is excessive, this is shown optically to the user via blue LED lighting. The color green indicates an intact power supply, while the color yellow indicates that the encoded path information is being read correctly from the magnetic tape or the magnetic ring.

Pluggable and ultra-compact
Another new feature is the plug connection right on the sensor. The combination of pluggable version and the status LED along with its unique compact design allows installation even where space is limited. This enables quick and accurate installation of the system and thus already helps save costs here. The new, robust and resistant plastic housing is mechanically compatible with the existing designs of MagLine magnetic sensors.

Flexibility in cable lengths and evaluation signals
The sensor provides digital square-wave signals with resolutions ranging from 0.1 mm to 0.001 mm, depending on sensor type. The optional cable extension KV1C in different cable lengths from one to 20 meters allows customers to decide which signals are actually used. The cable extension is available in 4-, 5-, 6-, or 8-wire versions. This enables the simple evaluation from A+B signal through to the evaluation of inverted signals and the periodic index signal using one and the same sensor. All these signals are already integrated in the standard version.
The sensor can even optionally be equipped with fixed or flexible reference point detection for detecting a reference mark on the hinge side.

Individually programmable
Using the programming tool PT5500, parameters such as resolution and pulse interval can be subsequently changed and the desired application customized. This reduces the number of versions, saves warehouse logistics costs and guarantees short delivery times.

Self-testing made easy
The MSC500 sensor system will already be available on the market as of the second quarter of 2016 and can be tested out free of charge on request by contacting SIKO GmbH.
