Wen­glor re­leases high-per­for­mance sen­sors with un­match­able ac­cu­racy

DEMM Engineering & Manufacturing - - ELECTRICAL TECHNOLOGY -

Re­li­able mea­sure­ment of ex­tremely small com­po­nents in the mi­cron range of­ten pushes op­ti­cal sen­sors be­yond their lim­its.

Now with the in­tro­duc­tion of its new PNBC range, Wen­glor is set­ting new stan­dards in ac­cu­racy with their max­i­mum res­o­lu­tion of 0.06μm with only 0.05 per­cent lin­ear­ity er­ror. This im­pres­sive pre­ci­sion is sup­ported by ex­cel­lent re­pro­ducibil­ity and ther­mal sta­bil­ity – even at out­put rates of up to 30kHz.

Wen­glor’s new range of PNBC sen­sors work with a high res­o­lu­tion CMOS line ar­ray and de­ter­mine dis­tance to the ob­ject by means of an­gu­lar mea­sure­ment.

Top qual­ity op­tics make mea­sured val­ues pos­si­ble which can be read out with 16-bit res­o­lu­tion and can thus go all the way down to 0.06μm.

Thanks to proven al­go­rithms, sta­ble mea­sured val­ues are ob­tained even for dif­fi­cult to mea­sure sur­faces, for ex­am­ple sheet metal with speckle ef­fect, and can be re­li­ably eval­u­ated.

With a max­i­mum range of 1000mm, PNBC prod­ucts are amongst the most ac­cu­rate sen­sors avail­able on the mar­ket and with mea­sur­ing fre­quen­cies of up to 30,000Hz, PNBC sen­sors are well above av­er­age rel­a­tive to other, com­pa­ra­ble dis­tance sen­sors.

Min­imised tem­per­a­ture drift makes use of the sen­sor pos­si­ble im­me­di­ately af­ter switch­ing it on with­out a long warm-up phase, and the sen­sor can get down to work with­out de­lay.

The mea­sured value is read out si­mul­ta­ne­ously via the ana­log out­put and the In­dus­try 4.0 com­pat­i­ble Eth­er­net TCP/ IP in­ter­face. This pro­vides users with the op­por­tu­nity of for­ward­ing data to higher-level sys­tem par­tic­i­pants di­rectly via net­work in­te­gra­tion.

The new sen­sors are equipped with up to four switch­ing out­puts, which can also be used as in­cre­men­tal en­coder in­puts or for switch­ing emit­ted light on and off.
