Turck presented a new magnetic field sensor for position detection of pneumatic cylinders at the Hannover fair. The BIM-UNT can detect all standard magnets in pneumatic cylinders, safely and without multiple switching points, which makes the stocking of different sensor types unnecessary. This new sensor allows the user to reduce stock and implement efficient standardisation.
Furthermore, the BIM-UNT is simple to mount and adjust. The sensor can be adjusted in the T groove of the cylinder and fixed in place using a wing screw made of tool steel. For vibration-resistant mounting it is simply enough to tighten the screw using a standard screwdriver or an Allen key. An LED indicator on the sensor assists the adjustment and positioning of the unit and shows switching status.
With a total length of only 28 mm the new sensor is one of the most compact on the market. The active faces are located at the sensor end and thus enable a reliable detection of the piston rod right up to the end position, even in compact short stroke cylinders. Apart from the vibration resistant mounting the excellent EMC properties guarantee high system availability. The BIM-UNT units not only fulfil the presently valid standard EN 609947-5-2, but also exceed the strict provisions of the upcoming amendment EN 61000-4-6, which will soon replace the current standard for proximity switches.
An extensive accessory programme is available for the BIM-UNT. These include mounting tools for other cylinder types such as profile, tie-rod, round and dovetail cylinders. Also available is a clip-on tool for fine tuning of the switching point, and the clips for safe cable routing.
