Specifications

Supply Voltage and Power

10 V DC to 30 V DC (10% maximum ripple) at less than 1 watt

each for emitter and receiver (exclusive of load)

Supply Protection Circuitry

Protected against reverse polarity and transient voltages

Output Configuration

Construction

Aluminum housing, die-cast zinc with black e-coat painted

endcaps, acrylic lens window

Application Notes

Minimum Object Detection Size (MODS)

Smallest diameter rod that can be detected in the sensing

range:

Short-Range: 5.6 mm (0.22 in)

Standard-Range: 9.5 mm (0.38 in)

Indicators

Emitter:

LED1 (green)

ON: Power ON, good sensor

OFF: Reduced Range

ON: Power ON, good sensor

LED2 (red)

ON: Reduced range

OFF: Normal range

Flashing: Emitter hardware failure

Receiver

LED1 (amber)

ON: Output conducting

OFF: Output not conducting

LED2 (bicolor green/red)

Green: Normal range

Red: Reduced range

Flashing Red: Receiver hardware failure

Connections

2 meter (6.5 ft) 5-conductor (with drain) PVC-jacketed

attached cable or a 150 mm (6 in) PVC-jacketed cable with a

5-pin M12 male quick-disconnect connector, depending on the

model

Environmental Rating

Meets IP65

Operating Conditions

–20 °C to +70 °C (–4 °F to +158 °F)

90% at +50 °C maximum relative humidity (non-condensing)

The best sensing resolution occurs within the center

80% of the sensing range (see "Theory of Operation"

on page 2 ).

1.

Low-profile packages can be reliably detected.

2.

Outputs are active while the light screen is

interrupted.

3.

For reliable detection, successive parts must be

spaced up to the total of ON-time plus OFF-time

apart (that is, 12 milliseconds for the LX12)
