Sensor Overview
The Q50 Complementary Discrete is an easy-to-use triangulation
sensor which provides a sophisticated, yet cost-effective
solution for demanding applications. Q50 Series sensors feature
compact, all-in-one design and require no separate controller.
Each sensor has two discrete outputs (both NPN or both PNP).
The complementary output can be configured for one of two
conditions:
•A sensing window consisting of two switch points
•A single switch point, as with an adjustable-field sensor
Optical Triangulation
The function of the Q50 Sensor is based on optical triangulation
(see Figure 1). The emitter circuitry and optics create a light
source which is directed toward a target. The light source
bounces off the target, scattering some of its light through the
sensor’s receiver lens to its position-sensitive-device (PSD)
receiver element. The target’s distance from the receiver
determines the light’s angle to the receiver element; this angle
determines where the returned light will touch the PSD receiver
element.
The position of the light on the PSD receiver element is
processed through digital electronics and analyzed by the
microprocessor. The microprocessor will compare the target
position to the taught window limits and then change the
discrete outputs as required.

Using the L-GAGE Q50 Complementary Discrete Output Sensor
Response Speed
Response speed is either Fast (4 ms) or Slow (48 ms), depending on model.
Window Limits
Window limits may be taught to the sensor either remotely (using the gray
wire) or by using the sensor’s Teach push button.
The Q50 sensor operates in two modes: TEACH (or programming) mode and
RUN mode.
NOTE: All LED indicators momentarily go OFF when the sensor changes state
between RUN and TEACH modes.
Indicator Status Conditions
Indicator Status
Range LED Green — Target is within sensing range
(green/red) Red — Target is outside sensing range
Flashing Green — Discrete output overloaded
OFF — Sensor Power OFF
Teach/Output Yellow (window limits) — Target is within taught limits
LED Yellow (fixed field) — Target is closer than cutoff limit
(yellow/red) OFF — Target is outside taught window limits
Red — Sensor is in TEACH mode
TEACH-Mode Programming
Push-Button Procedure for Teaching Window Limits (Complementary
Outputs)
1. Press and hold the Teach push button until the Teach LED turns red (depress
button for about 2 seconds). This indicates the sensor is waiting for the first
window limit.
2. Position the target for the first limit. The Range LED should be green,
indicating a valid target. Briefly “click” the Teach push button. This will teach
the sensor the first limit. The Teach LED will flash red at 2 Hz to
acknowledge receiving the first window limit; it is now waiting for the second
limit.
3. Position the target for the second limit and “click” the Teach push button
again to teach the sensor the second limit. The Teach LED will return to
either yellow or OFF as the sensor returns to RUN mode.
NOTE: The yellow LED follows the black wire output.

Push-Button Procedure for Teaching a Single Sensing Set Point
(Complementary Outputs – Adjustable-Field Style)
The black wire conducts when the target is inside the programmed set point. The white
wire conducts when the target is outside (away from) the set point (see Figure 7).
1. Press and hold the Teach push button until the Teach LED turns Red (depress button
for approximately 2 seconds).
2. Position the target at the sensing set point. The Range LED should be green,
indicating a valid target. Briefly “click” the Teach push button. This will teach the
sensor the first limit. The Teach LED will flash red at 2 Hz to acknowledge receiving
the first window limit; it is now waiting for a second limit.
3. Maintain the same target position and “click” the Teach push button again to teach
the same window position. The Teach LED will return to either yellow or OFF as the
sensor returns to RUN mode.
Note: The yellow LED will follow the black wire output.
Remote Programming
A function is provided to program the sensor remotely or to disable/enable the push
button; this is accomplished via the gray wire. Disabling the push button prevents
anyone on the production floor from adjusting any of the programming settings.
Connect the gray wire of the Q50 Sensor to +5 to 30V dc, with a remote programming
switch connected between them. NOTE: The impedance of the remote teach input is 15
kΩ.
To program, pulse the wire as illustrated in
Figure 6. NOTE: The duration of each pulse
(corresponding to a push button “click”) is
0.04 to 0.8 seconds.
Run Mode
NOTE: All LED indicators momentarily go
OFF when the sensor changes state
between RUN and TEACH modes.
Range LED
When the sensor detects a target within its
sensing range (either 100 to 300 mm for
visible-beam models, or 100 to 400 mm
for infrared beam models) the LED will be
solid green. In the absence of a target, the
Range LED is solid red. Refer to the
Indicator Status table on page 3.
Teach/Output LED
In RUN mode, the Output LED is yellow
when a target is sensed within the
programmed window limits; otherwise the
Output LED is red. Refer to the Indicator
Status table on page 3.
Complementary Discrete Outputs
The complementary discrete outputs are
either both NPN or both PNP. The outputs
are configured via the Teach procedure to
either a single window or a fixed-field
(single set point) application. The outputs
are short circuit-protected and can switch
up to 150 mA (resistive load).
