Photoelectric sensors now available in fixed-field sensing mode

December 2015 Sensors & Transducers

RET Automation now stocks the S18-2 compact photo-electric sensor series with fixed-field background suppression mode configurations. The compact, self-contained sensors provide up to six detection ranges from 30 to 200 mm to satisfy diverse cost-sensitive and high-volume applications.

Featuring excellent optical design and an advanced electronic design, Banner’s S18-2 background suppression sensors are resistant to fluorescent light and offer a high level of crosstalk avoidance. With a small, bright red LED emitter beam, S18-2 sensors are easy to align to the target, and ensure very small shifts in the detection range caused by target colour variation.

The S18-2 optics are factory calibrated to one of six sensing ranges between 30 and 200 mm to ensure consistent sensing performance. Machine builders can count on stable and robust detection with no risk of machine down time related to sensor adjustment. For customers requiring a range not in the catalogue, Banner is able to produce customer required fixed range sensors matched to a machine designer’s specific requirements.

For ease of use, S18-2 sensors feature a highly visible output, and dual-function power and stability indicators. The indicators are comprised of one green and two yellow LED lights. Solid green indicates power is applied and the sensor is ready, while green flashing specifies a marginal sensing signal. The two bright yellow LEDs, visible from both sides of the sensor, indicate the output is conducting.

Designed with a rugged ABS plastic housing, the sensors are well sealed against water ingress. A wide operating temperature range of -40 to 70 °C ensures optimal performance for diverse applications.
