Not To Be Used for Personnel Protection Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death. These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current Banner Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection. Printed in USA P/N 57890QMT42 Series Long-Range Diffuse Sensors QMT42DX Specifications Sensing Beam Infrared, 880 nm Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than 40 milliamps Supply Protection Circuitry Protected against reverse polarity and transient voltages Output Configuration SPDT (complementary) solid-state dc switch Choose NPN (current sinking) or PNP (current sourcing) models. Light operate: N.O. output conducts when the sensor sees its own modulated light Dark operate: N.C. output conducts when the sensor sees dark Output Rating 100 mA maximum (each output) Off-state leakage current: <5 microamps at 30V dc On-state saturation voltage: <1V at 10 mA dc <1.5V at 100 mA dc Output Protection Circuitry Protected against false pulse on power-up and continuous overload or short-circuit of outputs Overload trip point 130mA, typical, at 20C Output Response Time 1 millisecond on and off NOTE: 100 millisecond delay on power-up outputs are non-conducting during this time Repeatability of Response 250 microseconds Sensing Hysteresis Less than 20% of set sensing distance Adjustments 4-turn slotted Gain (sensitivity) adjustment potentiometer (clutched at both ends of travel) Indicators Two LEDs: Green and Yellow GREEN glowing steadily = power to sensor is ON GREEN flashing = output is overloaded YELLOW glowing steadily = light is sensed normally open output ON YELLOW flashing = marginal excess gain (1-1.5x) in light condition Construction Housings are die-cast zinc alloy with black acrylic polyurethane finish lenses are acrylic Environmental Rating IP67 NEMA 6 Connections 2 m (6.5 ) or 9 m (30 ) attached cable, or 4-pin Euro-style quick-disconnect fitting Cables for QD models are purchased separately Operating Temperature -20 to +55C (-4 to +131F) Maximum relative humidity 90% at 50C (non-condensing) Certifications Approvals in process QMT42DX Dimensions Cabled models Quick-Disconnect models 18.0 mm (0.71 ) Green LED Power/Overload Indicator Yellow LED 19.2 mm Output/Marginal Indicator (0.76 ) 3.2 mm (0.125 ) (4 Holes) 58.0 mm 76.2 mm M12 x 1 x 18 mm (2.28 ) (3.00 ) Euro-style 2 x 3.1mm (0.12 ) 10.0 mm (0.39 ) 2 x 3.1mm (0.12 ) 12.3 mm 23.9 mm (2) (0.48 ) (0.94 ) 27.1 mm (2) 42.0 mm (1.07 ) Threaded M4 x 0.7 (1.65 ) Mounting Holes page 2
