ANSI/IEEE Photoelectric emitter-receiver switch form
IEEE-library form of photoelectric emitter-receiver switch: a photoelectric emitter-receiver device uses an optical path to determine a switching output.
In plain English
What does ANSI/IEEE Photoelectric emitter-receiver switch form mean?
This reference locates photoelectric emitter-receiver switch in Autodesk's IEEE-oriented photoelectric emitter/receiver switches family. A photoelectric emitter-receiver device uses an optical path to determine a switching output. The schematic needs the supply and output connections, while the layout defines the optical arrangement. The public library uses HPE11B16 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Read the operating mechanism and the contact reference state together. Cross-reference every associated contact to the same device and show which movement, signal or reset changes its condition; the symbol alone does not establish the complete switching sequence.
What the drawings help you do
Establish whether the indicated state corresponds to a received or interrupted beam. Optical detection is not the same sensing principle as inductive or capacitive proximity. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

- The contact state in the normal condition defined for the drawing.
- Terminal
- An identified point where a conductor connects.
- Signal
- Electrical information passed between devices, rather than necessarily the main power supply.
