IEC combined photoelectric sensor: form c emitter-receiver DC driven 5 pin
Combined photoelectric sensor form: FORM C Emitter-Receiver DC Driven 5 PIN.
In plain English
What does IEC combined photoelectric sensor: form c emitter-receiver DC 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 dc 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 DC-supplied form. Preserve supply polarity and confirm the output circuit type from the device wiring 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 DC Driven 5 PIN. This entry adds the form c emitter-receiver dc 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.
- DC
- Direct current: electricity flowing in one direction.
- Terminal
- An identified point where a conductor connects.
- Signal
- Electrical information passed between devices, rather than necessarily the main power supply.

How to read it
- 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.
- This is the DC-supplied form. Preserve supply polarity and confirm the output circuit type from the device wiring 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.
Information to show or reference
- Identify the target, sensing mode and expected normal condition.
- Label supply, output and connector pins from the actual device diagram.
- Reference output circuit type, operating range and controller input.
A distinction that matters
This entry adds the form c emitter-receiver dc 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.
