T8 Opposed-Mode Sensor Specifications
Supply Voltage and Current
Application Notes
Supply Protection Circuitry Protected against reverse polarity and transient voltages
Output Configuration SPST solid-state switch
Choose NPN (current sinking) or PNP (current sourcing) models
Choose light operate (N.O.) or dark operate (N.C.) models
Output Rating 50 mA maximum
Off-state leakage current: < 1 microamp at 24V dc
On-state saturation voltage: < 0.25V at 10 mA dc; < 0.5V at 50 mA dc
Output Protection Circuitry Protected against false pulse on power-up and continuous overload or short circuit of outputs
Overload trip point ≥ 100 mA
Output Response Time 1 millisecond ON and 0.5 millisecond OFF
(NOTE: 100 millisecond delay maximum on power-up; output does not conduct during this time)
Indicators Receiver has both Green and Red LEDs
Emitter has one Green LED
Green ON steady = power to sensor is ON
Green flashing = output overload
Red ON steady = light is sensed
Red flashing =marginal excess gain (1-1.5x) in light condition
Repeatability 100 microseconds
Reinforced polycarbonate/ABS alloy 8 mm threaded nut (included).
Optional mounting bracket is available (page 4).
Construction Reinforced polycarbonate/ABS alloy housing, acrylic window
Environmental Rating IEC IP67; NEMA 6
Connections 2 m (6.5') attached cable: three #28 ga stranded conductors with PE insulation; PVC outer cable jacket;
or 3-pin Pico-style pigtail quick-disconnect fitting. QD cables are ordered separately.
Operating Conditions Temperature: -20° to +55°C (-4° to +131°F)
