Photoelectrics Type EF 1801 Fiber Optic Sensor • • • • • • • • • • Product Description Used in through-beam, retroreflective or diffuse-reflective applications depending upon how the additional fibers are mounted. Easily adjustable sensitivity with 270° potentiometer. LED indication for out- Range: Fiber dependent, typ. 100 mm Adjustable sensitivity Modulated, red light Rated operational voltage: 10 to 40 VDC Output: DC 200 mA NPN or PNP Make and break switching function, LED indication Heavy duty M18 metal housing, IP 67 Cable and plug versions For 2.2 mm fiber cable with 1 mm core MB 18 A for DIN-rail mounting (see Accessories) Ordering Key put ON. Short M18 metal housing for heavy duty applications. The fiber allows positioning and mounting in tight spaces with the photoelectric sensor itself mounted in a more convenient location.

The fiber entries are now open for putting in the fibers. • Put in the fibers. Be sure that the fibers pass the constriction near the bot- tom of the hole. The constriction seals the junction (between fiber and photo element) against dust. The sensing distance will be reduced if there is an air gap between the fiber and the photo element. 1 FIBER FIBER 2 FIBER FIBER ENTRY ENTRY TRANSMITTER TRANSMITTER OR RECEIVER OR RECEIVER 2 • Release the clamp to fix the fibers. Installation Hints To avoid interference from inductive voltage/ current peaks, separate the prox. switch power cables from any other power cables, e.g. motor, contactor or solenoid cables Relief of cable strain Protection of the sensing face Switch mounted on mobile carrier A proximity switch should not serve as mechanical stop Any repetitive flexing of the cable should be avoided Incorrect Correct The cable should not be pulled Specifications are subject to change without notice (06.03.2006) 3
