Photoelectric sensor provides dual outputs
This miniature photoelectric sensor, the Q19 measures only 0.43 x 1.32 x.
74 in (11 x 34 x 19 mm). It has a sensing range from 2 to 80 in. (5 cm to
2 m). The sensor provides two outputs, one normally open and the other
normally closed. Each output is capable of up to a 150 mA continuous load.
Furthermore, one of these complementary outputs can be used as an alarm to
signal a controller or energize an external alarm whenever sensing
conditions become marginal, alerting the operator in advance of sensor
failure due to an obscured lens or dirty sensing environment. Leds
mounted on top to the sensor allows the user to monitor conditions. Power
on, output overload, object sensed, and low gain. The Q19 comes with a 6
1/2-ft-long attached PVC-covered four-wire cable or a miniature
quick-disconnect and requires 10 to 30 Vdc for operation. It is completely
sealed and its circuitry is epoxy-encapsulated. (xxx–xxx.) Banner
