MULTI PORT-FIBER OPTIC RECEPTACLE FOR POSITION/OBJECT SENSING APPLICATIONS

by Gary Kloesz

  Sensing o[ objects can be accomplished using fiber optics. The fiber would carry the light to and from the sensing point, leaving the electronics in a central location.

  This Fiber Optic Connector was fashioned after "Electrical Duplex Sockets" that are readily availa- ble for home electrical wiring. The intent of this connector is to allow easy insertion and removal of fiber optic cable. Presently, the only alternative is a single point connection using the FLCS connector. When multiple connections are required, the FLCS is costly and tedious for manufacturing.

  The basic plastic housing allows the mixing of emitters and detectors as required by the customer. This housing could be manufactured in various sizes

from 2 to 10 fibers.

  Sensing applications are usually "short distance" and simple on-off inputs. Because of this, critical alignment is minimized and the cable could be cut

with a blade and inserted into the housing.

APPLICATIONS INCLUDE

  Object sensing along assembly lines and ware- house systems. Position sensing of moving objects in machinery, print head position, and rotary encoders. Depending on the fiber positioning accu- racy, additional applications may include low speed- multiple serial data or parallel data requirements, along with EMI reduction of data lines entering/ exiting a "RF" sealed enclosur...
