New shock-resistant linear position sensors

and punching machines as well as in wood processing or injection molding machines. The Li linear position sensors always supply their output signal twice: as a 0 - 10 V signal and as 4 - 20 mA signal.This makes it pos- sible to connect diagnostic systems and also reduces the number of device variants to be kept in reserve.

The new Li linear position sensors fromTurck Banner measure po- sition values at a frequency of 5 kHz, at measuring lengths of up to 2 m. Turck has updated its contactless Li Q25 positioning systems and has now added new, extended variants to the range. The in- ductive measuring principle used in the Li sensors offers improved shock resistance and sampling rate compared to alternative meas- uring systems. With measuring lengths of up to 2 m, the Li sen- sors outperform magnetostrictive linear position sensors which, because of their operating principle, sense at a slower rate as the measuring length increases. The new IP67 sensors are resistant to harsh environmental con- ditions, humidity and dirt. They also reliably output a position signal even when subject to vibration or shocks of up to 200 g. The 5 kHz scan rate keeps positioning errors to a minimum – a benefit that was previously difficult to achieve in rugged applications. Precision has also been further enhanced with a 16-bit digital-to-analogue (D/A) converter. With their immunity to magnetic fields, Li sensors are generally ideal for closed-loop control tasks in the metalworking industry, as the metal shavings accumulated here do not stick to the posi- tioning element inducing linearity errors. The sensors’ shock resist- ance means they can be used for position measurement in presses

The new Li linear position sensors are available in measuring lengths from 100 to 2 000 mm.
