Micro Switch Photoelectric Sensors
This Micro Switch is brand-new and has never been used, (it's from old stock)
This switch was in the shop for several years on a supply shelf, it is new with a 7' - 3 conductor cord. the specification sheet is included for wiring configuration.
FE7B sensors arc available with invisible infrared emitters. The infrared type is most stable when sensing a wide variety of colors. Since these sensors are self contained, no separate amplifier is needed for signal conditioning. A mounting bracket is included to simplify mounting and alignment. This sensor is ideal for mounting in space constricted areas and performing small part detection. The stainless steel tube can be flexed in any direction allowing accurate positioning of the sensing fibers. Care should be taken with the benda ble tube so the glass fiber bundle is not broken. Bend using a minimum radiu s of.4 inch and only bend in the middle of the tube. See drawing. Do not twist tube.
O.32-inch visible red diffuse scan range O.4-inch infrared diffuse scan range 10 to 28 VDC operation Sealing: NEMA 12 and IP64 Combination alignment/self diagnostic indicator False pulse protection Short circuit and reverse polarity protection Light or dark operated selectable Prewired cable termination 2 m (6') Glass fiber optic bundle is enclosed in bendable stainless steel tubing Ease of installation
FE7B sensors incorporate a self-diagnostic function alignment indicator. When sufficient light level is being received, the indiCa[ or light is green. But when the light level decreases to 150% of the minimum operating level the indicator turns red . Thi s simplifies installation, alignment, and troubleshooting.
