Bulletin 45AST Area Array

Description

The Allen-Bradley 45AST Area Array is a compact, easy-to­use nonsafety light screen for small part detection and
assembly applications. This transmitted beam array is ideal for
use in a variety of applications from counting to process
initiation.

The 45AST introduces “Two-Dimensional Array Scanning
Technology” which allows the user to sense an object as it
passes through the pair of arrays regardless of orientation
provided that one axial dimension meets the minimum
resolution requirements.

Features/Benefits

S Two dimensional array scanning technology
S Minimum object resolution (from 1117 mm

(0.430.66in.)

S Sensing ranges up to 2.5 m (8.2 ft)
S Highly visible alignment LEDs
S Easy bracket-free mounting
S IP67 rated enclosure

Sensor Alignment

1. Visually align the emitter and receiver units until the
orange output LED turns ON.

2. To ensure that the beam is centered, it is recommended to
sweep the emitter or receiver in the horizontal and vertical
plane and determine at what position the output indicator
turns ON and then turns OFF. Set the sensor midway
between both positions.

Interference Protection

To minimize interference and false triggering from highly
reflective objects, keep object within a minimum distance of
100 mm (4in.), parallel to the effective beam center line.

Maintenance

ATTENTION

To avoid intermittent operation, do not
mount the sensors to surfaces that may
shift or be exposed to excessive vibration.

ATT E N T ION

When cleaning the face of the sensor, do
not use aggressive or abrasive materials
which could reduce the operating range
and accuracy.

Securely mount the sensor on a firm, stable surface or
