Combined photoelectric sensor form: FORM C Emitter-Receiver AC Driven 5 PIN. ## In plain English ### What does IEC combined photoelectric sensor: form c emitter-receiver AC driven 5 pin mean? A combined photoelectric sensor contains an emitter and a receiver within the same documented sensing unit. This entry identifies the form c emitter-receiver ac driven 5 pin form in the publisher's IEC-context family. ### A simple example A reflective sensing arrangement can detect a passing object or a change in returned light and send the result to a control input. Form C identifies a changeover output with a common and two alternative paths; it does not establish which terminal numbers the selected device uses. The additional connection points need the actual pin assignment. A fourth or fifth pin may serve an output or control function; pin count alone does not define its purpose. ### What the drawings help you do This is the AC-supplied form. Supply and switched output must be checked separately rather than substituting a DC sensor connection diagram. The combined housing does not establish whether a reflector or the target returns the light. Sensing mode, light-on or dark-on selection and pin functions need the selected product diagram. ### This particular reference Combined photoelectric sensor form: FORM C Emitter-Receiver AC Driven 5 PIN. This entry adds the form c emitter-receiver ac driven 5 pin detail to the broader combined photoelectric sensor family. The combined housing does not establish whether a reflector or the target returns the light. Sensing mode, light-on or dark-on selection and pin functions need the selected product diagram. ### Terms - DC: Direct current: electricity flowing in one direction. - AC: Alternating current: electricity whose direction changes periodically. - Terminal: An identified point where a conductor connects.
