• To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, Q20E W/30.
• To order the 4-pin M8 integral quick disconnect model, add the suffix "Q7" to the model number. For example, Q20EQ7.
• To order the 150 mm (6 in) PVC cable model with a 4-pin M8 quick disconnect, add the suffix "Q" to the model number. For example, Q20EQ.
• To order the 150 mm (6 in) PVC cable model with a 4-pin M12 quick disconnect, add the suffix "Q5" to the model number. For example, Q20EQ5.
• To order the 150 mm (6 in) PUR cable model with a 4-pin M12 quick disconnect, add the suffix "QPMA" to the model number. For example,
Q20EQPMA.
• Models with a quick disconnect require a mating cordset.

 WORLD-BEAM® Q20 Series Sensor

Overview
Banner’s Q20 family of sensors offers a full complement of sensing (varies with model)
modes, with the excellent performance expected of much larger 3 1. Output LED
sensors. Their compact plastic housings feature overmolded 2 2. Power LED
construction for superior robustness and sealing. Their popular
rectangular design is easy to mount into tight spaces; integral 3. Single-Turn Gain
threaded mounting holes eliminate the need for separate mounting 1 Potentiometer (Retro
nuts. and Diffuse models
only)
The single-turn Gain potentiometer on most models and bright
LEDs (positioned on top of the housing for 360° visibility) provide
easy alignment and configuration for reliable sensing.

Applications Notes Required Overcurrent Protection

1. Opposed mode sensor spacing can be reduced by alternating
emitters and receivers or by applying cross talk filters (visible red WARNING: Electrical connections must be
models only) made by qualified personnel in accordance
with local and national electrical codes and
2. For receiver only: NPN off-state leakage current is <200 µA for load regulations.
resistances > 3kΩ or optically isolated loads. For load currents of
100 mA, leakage is <1% of load current. Overcurrent protection is required to be provided by end product
Operating Conditions application per the supplied table.
Overcurrent protection may be provided with external fusing or via Current

FCC Part 15 and CAN ICES-3 (B)/NMB-3(B)

This device complies with part 15 of the FCC Rules and 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.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules and CAN ICES-3 (B)/NMB-3(B). These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. 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 manufacturer.
