Overview

This small, rugged infrared diffuse proximity mode sensor is contained within an 8-
mm deep die-cast metal housing. It is totally self-contained and is powered by 10 to
30V dc. It is ideal for sensing of any reflective surface at up to 2 inches from the
sensor face. Typical applications include parts detection on small conveyors and in
robot grippers, and other similar short-range sensing applications.
Q08 diffuse sensors have a solid-state output capable of switching loads of up to
150 mA dc, continuous. Four output types are available: NPN sinking/light operate,
NPN sinking/dark operate, PNP sourcing/light operate, and PNP sourcing/dark op-
erate.
A light-operate output conducts when the sensor sees the reflection of its own
modulated light (an object is present). A dark-operate output conducts when the
sensor does not see the reflection of its own modulated light (no object is present).
A green LED indicator, visible from the front and left side of the sensor, lights when-
ever dc power is applied to the sensor. An amber LED, visible from the front and
right side of the sensor, lights whenever the sensor output is conducting.

Specifications

Supply Voltage and Current

10 to 30V dc at 25 mA; 10% maximum ripple

Supply Protection Circuitry

Protected against reverse polarity

Indicators

Two LED indicators:
Green: Lights to indicate dc power ON
Amber: Lights when sensor output is conducting (in
“light” condition for light operate models; in “dark” con-
dition for dark operate models)

Construction

Black epoxy-painted die-cast zinc housing, polysulfone
thermoplastic lens with two through-mounting holes to
accommodate M3 (#4) hardware

Environmental Rating

Meets NEMA standards 1, 2, 4, 6, 12 and 13; IEC IP67

Connections

PVC-jacketed 2 m (6.5 ft) or 9 m (30 ft) cable or 3-pin
Pico-style quick-disconnect (QD) fitting available. Ca-
ble is 4.0 mm (0.16 inches) diameter.

Operating Conditions

Temperature: 0 to +50 °C (+32 to +122 °F)
Maximum relative humidity: 90% at 50 °C (non-con-
densing)

Output Configuration

Solid-state dc output, with four output types available:
NPN sinking/light operate
PNP sourcing/light operate
NPN sinking/dark operate
PNP sourcing/dark operate
Light operate outputs conduct when the receiver sees
the reflection of its own modulated light source; Dark
operate outputs conduct when the sensor sees dark.

Output Rating

150 mA maximum, continuous
Off-state leakage current is 100 microamps at 30V dc
On-state saturation voltage is < 200 millivolts at 10 mA
dc and < 1 volt at 150 mA dc

Output Response Time

1 millisecond ON and OFF independent of signal
strength

Repeatability

200 microseconds (0.2 milliseconds), independent of
signal strength

Application Notes

The horizontal axis of the beam pattern represents a
line extending outward from the optical center of the
Q08 sensor, and perpendicular to the sensor’s lens.
For purposes of mounting and alignment, note that the
optical center of the Q08’s lens is not the same as its
mechanical center.
