MULTI-BEAM
2-Wire Scanner Blocks
SPECIFICATIONS
SUPPLY VOLTAGE: connections are made via a 2-wire power
block (see page 27).
RESPONSE TIME: 10 milliseconds ON and OFF (3000 operations
per minute). NOTE: a built-in false pulse protection circuit holds the
output off for 100 milliseconds after power is initially applied to the
sensor.
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 with a small screwdriver 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.
CONSTRUCTION: reinforced VALOX
totally encapsulated. Stainless steel hardware. Meets NEMA stan-
dards 1, 3, 12, and 13.
OPERATING TEMPERATURE RANGE: -40 to +70 degrees C
(-40 to +158 degrees F).

housing with components
The components of the MULTI-BEAM 2-wire family of modular self-contained
sensors are physically identical to the 3- & 4-wire components. However, the 2-
wire components are designed to wire directly in series with an ac load, exactly
like a limit switch. This design makes the 2-wire MULTI-BEAM impossible to
wire backward.
MULTI-BEAM 2-wire scanner blocks with their 10 millisecond response time
have approximately the same optical performance as the 1-millisecond 3- & 4-
wire scanner block models.
The off-state leakage current of 2-wire MULTI-BEAM sensors is less than 1
milliamp, the lowest value of any 2-wire photoelectric sensor. This makes the
MULTI-BEAM 2-wire photoelectric device the most probable such device to
interface directly with ac inputs of programmable logic controllers (PLCs).
