PHOTOELECTRICS RepeatabilityOpposed: 0.13 milliseconds; Retroreflective and Diffuse: 0.25 milliseconds FPY High-Speed Plastic Fiber Optic: 25 microseconds Response time and repeatability specifications are independent of signal strength. Adjustments SENSITIVITY control (single-turn, o-ring sealed potentiometer) Indicators Sensors except opposed mode emitters have two LEDs: Green ON steady: dc power ON Green flashing: output overload Yellow ON steady: Light Operate (LO), output is energized Yellow flashing: marginal excess gain (1 - 1.5x), LO output is energizedEmitters have green power “ON” indicator Construction Yellow and black ABS housing, with acrylic lenses, completely sealed. Stainless steel mounting bracket and M3 mounting hardware are supplied Environmental Rating Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 6, 12, and 13; IEC IP67. Housing materials rated UL 94 V-0 Connections PVC-jacketed 4-conductor 2 m or 9 m cables, or 4-pin Pico-style 50 mm threaded quick-disconnect (QD) fitting are avail able. Mating QD cables are ordered separately. See page 378. Operating ConditionsTemperature: -20° to +55° C Relative humidity: 90% at 50° C (non-condensing) Application Notes To avoid damage to the sensor caused by static discharge (ESD), use the plastic screwdriver supplied with each sensor (included in the hardware packet) to adjust the SENSITIVITY control. Otherwise, use a screwdriver with an insulated handle. Certifications Hookup DiagramsEmitters: DC03 (p. 476) NPN Models: DC07 (p. 477) PNP Models: DC08 (p. 477)
