IEC photoelectric receiver: normally open receiver - DC driven
Photoelectric receiver form: Normally Open Receiver - DC Driven.
In plain English
What does IEC photoelectric receiver: normally open receiver - DC driven mean?
A photoelectric receiver evaluates light arriving from an associated emitter and provides the documented electrical response. This entry identifies the normally open receiver - dc driven form in the publisher's IEC-context family.
A simple example
An object crossing a conveyor beam can change the receiver output. The receiver tag should identify its optical partner and the controller input receiving its signal. The normally-open designation starts with a non-conducting output or open contact in the documented reference condition; operation changes that state. This is the DC-supplied form. Preserve supply polarity and confirm the output circuit type from the device wiring diagram.
What the drawings help you do
Normally-open and normally-closed labels describe the documented electrical output form. They do not by themselves establish light-on or dark-on operation; confirm that setting with the device data.
This particular reference
Photoelectric receiver form: Normally Open Receiver - DC Driven. This entry adds the normally open receiver - dc driven detail to the broader photoelectric receiver family. Normally-open and normally-closed labels describe the documented electrical output form. They do not by themselves establish light-on or dark-on operation; confirm that setting with the device data.

How to read it
- The normally-open designation starts with a non-conducting output or open contact in the documented reference condition; operation changes that state.
- This is the DC-supplied form. Preserve supply polarity and confirm the output circuit type from the device wiring diagram.
- Normally-open and normally-closed labels describe the documented electrical output form. They do not by themselves establish light-on or dark-on operation; confirm that setting with the device data.
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 normally open receiver - dc driven detail to the broader photoelectric receiver family. Normally-open and normally-closed labels describe the documented electrical output form. They do not by themselves establish light-on or dark-on operation; confirm that setting with the device data.
