Q45AD9 NAMUR Series Sensor
Datasheet
No revision without agency approval.
•
Designed for use with approved amplifiers and intrinsically safe barriers in
explosive environments
•
•
•
NAMUR compliant sensor with the rugged design and excepꢀonal opꢀcal
performance of Q45 series sensors
Output passes ≤ 1.2 mA in the “dark” condiꢀon and ≥ 2.1 mA in the “light”
condiꢀon
Internal mulꢀ-turn SENSITIVITY (Gain) control accessible beneath hinged, o-ring
sealed top cover
•
•
Models are available with an integral cable or a quick-disconnect connector
Supply voltage: 5 to 15 V dc
WARNING: Not To Be Used for Personnel Protecꢀon
Never use this device as a sensing device for personnel protecꢀon. Doing so could lead to serious injury or death.
This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety
applicaꢀons. A sensor failure or malfuncꢀon can cause either an energized or de-energized sensor output
condiꢀon.
Models
Standard 2 m (6.5 ꢁ) cable models are listed. To order the 9 m (30 ꢁ) cable model, add suffix "W/30" to the cabled model number
(Q459E W/30). Models with a QD connector require a maꢀng cable (see Accessories list).

Retroreꢂecꢀve Models
Retroreꢂecꢀve range is specified using one model BRT-3 P retroreꢂector (3-inch diameter). Actual sensing range may be more or less
than specified, depending upon the efficiency and reꢂecꢀve area of the retroreꢂector(s) in use.
