MULTI-BEAM 3- & 4-WIRE

SCANNER BLOCKS

DESCRIPTION

MULTI-BEAM 3- & 4-wire scanner blocks offer a complete comple-

ment of sensing modes. There are 3 or more models for each sensing

mode, resulting in a choice of exactly the right sensor for any applica-

tion. The high power models (10 millisecond response time) offer

greater optical sensing power than any other industrial sensors.

SPECIFICATIONS

SUPPLY VOLTAGE: input power and output connections are made

via a 3- or 4-wire power block (see pages 15 to 20).

RESPONSE TIME: 1 millisecond ON and OFF, except high gain

models with "X" suffix and ambient light receivers which are 10

milliseconds ON and OFF.

REPEATABILITY OF RESPONSE: see individual sensor specs.

SENSITIVITY ADJUSTMENT: easily accessible, located on top of

scanner block beneath o-ring gasketed screw cover. 15-turn clutched

control (rotate clockwise to increase gain).

ALIGNMENT INDICATOR: red LED on top of scanner block.

Banner's exclusive, patented Alignment Indicating Device (AID™)

circuit lights the LED whenever the sensor detects its own modulated

light source, and pulses the LED at a rate proportional to the received

light level.

totally encapsulated. Stainless steel hardware. Meets NEMA standards

1, 3, 12, and 13.

OPERATING TEMPERATURE RANGE:

-40 to +70 degrees C

(-40 to +158 degrees F).
