Q25 DC Specifications

Supply Voltage and Current 10 to 30V dc (10% max. ripple); Supply current (exclusive of load current): Opposed Mode Emitters: 25 mA Opposed Mode Receivers: 20 mA Polarized Retroreflective: 30 mA Fixed-field: 35 mA Supply Protection Circuitry Protected against reverse polarity and transient voltages Output Configuration Solid-state complementary (SPDT) dc switch; NPN (current sinking) or PNP (current sourcing), depending on model.The Dark Operate (DO) output may be wired as a normally open marginal signal alarm output, depending upon hookup to the power supply. Output Rating 150 mA max. (each) in standard hookup. When wired for alarm output, the total load may not exceed 150 mA Off-state leakage current: less than 1 mA at 30V dc On-state saturation voltage: less than 1V at 10 mA dc; <1.5V at 150 mA dc Output Protection Circuitry Protected against false pulse on power-up and continuous overload or short circuit of outputs Output Response TimeOpposed: 3 milliseconds ON, 1.5 milliseconds OFF; Polarized Retroreflective and Fixed-field: 3 milliseconds ON/OFFNOTE: 100 millisecond delay on power-up; outputs do not conduct during this time RepeatabilityOpposed: 375 microseconds; Polarized Retroreflective and Fixed-field: 750 microseconds. Repeatability and response are independent of signal strength. IndicatorsTwo LEDs: Green and Yellow Green ON steady: power to sensor is ON Green flashing: output is overloaded (dc models only) Yellow ON steady: Light Operate (LO) output is energized Yellow flashing: excess gain marginal (1-1.5x) in light condition, LO output is energized Construction Housings are thermoplastic polyester. Lenses are polycarbonate or acrylic; come with one jam nut. Environmental Rating Leakproof design rated NEMA 6P, DIN 40050 (IP69K) Connections 2 m or 9 m attached cable, or 4-pin Euro-style quick-disconnect fitting. QD cables are ordered separately. See page 380. Operating ConditionsTemperature: -40° to +70° C Relative humidity: 90% at 50° C (non-condensing) Vibration and Mechanical Shock All models meet Mil. Std. 202F requirements. Method 201A (Vibration; frequency 10 to 60 Hz, max., double amplitude 0.06-inch acceleration 10G). Method 213B conditions H&I (Shock: 75G with unit operating; 100G for non-operation) Certifications
R Hookup DiagramsEmitters: DC03 (p. 476) NPN Models: DC07 (p. 477) PNP Models: DC08 (p. 477)
