Glass Fiber Optic Sensors
Notes
See listing of compatible connector cables on Page V8-T5-103.
1
All sensor heads feature a light or dark operation selector switch which reverses the output function.
2
Logic module must be ordered separately, see Page V8-T5-102. These sensor bodies are rated NEMA 4, 4X and 13.
3
Receptacles feature terminal wiring with a 1/2 in NPT thread at the conduit entrance.
Other connection options are available (see below and Page V8-T5-103).
4
Requires glass fiber optic cables for operation (not included), see Tab 9, section 9.2.
5
Sensing range for diffuse reflective mode for 0.125 in (3.2 mm) diameter fibers. See Page V8-T5-104 for complete sensing range specifications.
6
Sensing range in thru-beam mode for 0.125 in (3.2 mm) diameter fibers. See Page V8-T5-104 for complete sensing range specifications.
