| Safe detection of pistons in pneumatic cylinders |
|
New magnetic field sensors from Turck guarantee simple singlehand. Magnet field sensors for detection of piston positions in pneumatic cylinders are standard in industrial automation. |
They are purchased, installed and then usually quickly forgotten. But woe betide if a sensor is poorly adjusted or comes loose in its mounting. Then the machine comes to a standstill – and often the entire production line. The new magnetic field sensor family BIM-UNT from Turck helps here.
The cheapest method for detection of pneumatic cylinders up to now was without a doubt the use of reed switches. The attractive price was the only advantage that these switches could show compared to fully electronic sensors. The electronic sensors have tangible advantages such as they are bounce-free, wear-free due to the absence of moving parts, the contacts do not stick, there is no increase in the transfer resistances, no multiple switch points, etc. Electronic switches are based on different function principles such as the Hall effect, the magneto-resistive effect or the saturable-core effect.. Based on its design you can assume that the electronic cylinder switch will reliably perform its service in all its applications over a very long period.
Same price level as reed switches
Turck can now eliminate the last positive aspects of reed contacts with the BIM-UNT-AP7X which celebrated its premiere at the Motek. With a comparable price level to reed contacts this new member of the magnetic sensor family offers all the benefits of fully-electronic switches. The new contender in the field should be particularly interesting to machine manufacturers and OEMs. The maximum operating current of 50 mA is sufficient for most applications.
There are further models available in the BIM-UNT family for higher operating currents or other qualifications, which correspond with the particular demands in terms of pneumatic cylinder sensors: small construction designs, robust housing, flexible attachment features as well as minimum installation effort. – possibly all from a single source. Turck developers designed the new generation of T-groove cylinder sensors according to these specifications in close contact with users...
