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).
