## Overview 

The Q20-2 polarized retroreflective sensors offer excellent sensing performance in a compact plastic housing that is easily integrated into tight spaces. 

Threaded brass inserts provide stable mounting points, and the bright indicators provide user feedback of the sensor status. The single-turn gain potentiometer, LO/DO switch, and bright indicator LEDs provide easy alignment and configuration for reliable sensing. 

1. Green: Power Indicator 

2. Amber: Light Sensed Indicator (flashes for marginal conditions) 

3. Single-turn Gain Potentiometer (some models) 

4. Light Operate/Dark Operate Switch (some models) 

## Mount the Device 

1. If a bracket is needed, mount the device onto the bracket. 

2. Mount the device (or the device and the bracket) to the machine or equipment at the desired location. Do not tighten the mounting screws at this time. 

3. Check the device alignment. 

4. Tighten the mounting screws to secure the device (or the device and the bracket) in the aligned position.

In dark operate (DO) mode, the output is ON when the target returns less light to the sensor than the configured target and OFF when the sensor detects more light than the configured/taught target. 

In light operate (LO) mode, the output is ON when the target returns the same or more light to the sensor and OFF when the sensor detects less light than the configured/taught target. 

In retroreflective sensing modes, light operate is active when the beam is unblocked and dark operate is active when the beam is blocked. 

## Specifications 

Supply Voltage Output Configuration 10 V DC to 30 V DC (10% maximum ripple within specified Single output type (PNP or NPN), light operate (LO), dark limits) at less than 20 mA, exclusive of load operate (DO), or complementary (one light operate and one dark operate), depending on model Sensing Beam Rating: 100 mA total output current Visible red LED, 645 nm Off-state leakage current: < 10 µA at 30 V DC Supply Protection Circuitry ON-state saturation voltage: PNP: < 3 V at 100 mA; NPN: < 3 Protected against reverse polarity and transient voltages V at 100 mA

If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: 

- Reorient or relocate the receiving antenna. 

- Increase the separation between the equipment and receiver. 

- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. 

- Consult the dealer or an experienced radio/TV technician for help. 

(Part 15.21) Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. 

## Industry Canada ICES-003(B) 

This device complies with CAN ICES-3 (B)/NMB-3(B). Operation is subject to the following two conditions: 1) This device may not cause harmful interference; and 2) This device must accept any interference received, including interference that may cause undesired operation. 

Cet appareil est conforme à la norme NMB-3(B).
