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 exceptional optical

performance of Q45 series sensors

• Output passes ≤ 1.2 mA in the “dark” condition and ≥ 2.1 mA in the “light”

condition

• Internal multi-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 Protection

Never use this device as a sensing device for personnel protection. 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

applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output

condition.

Models

Standard 2 m (6.5 ft) cable models are listed. To order the 9 m (30 ft) cable model, add suffix "W/30" to the cabled model number

(Q459E W/30). Models with a QD connector require a mating cable (see Accessories list).
