Supply Voltage and Power 10 to 30V dc (10% maximum ripple) at less than 1 watt each for emitter and receiver (exclusive of load)
Supply Protection Circuitry Protected against reverse polarity and transient voltages
Sensing Range Normal (see hookups) Reduced
Short-Range Models 100 to 200 mm (4" to 8") 75 to 150 mm (3" to 6")
Standard-Range Models 300 mm to 2 m (1' to 6.5') 150 mm to 600 mm (6" to 24")
Output Configuration Bipolar: One current sourcing (PNP) and one current sinking (NPN) open-collector transistor
Output Rating 125 mA maximum each output
Off-state leakage current: less than 5 microamp
Output saturation voltage (PNP output): < 1 volt at 10 mA and < 1.5 volts at 100 mA
Output saturation voltage (NPN output): < 0.5 volts at 10 mA and < 0.6 volts at 100 mA
Output Protection Circuitry Protected against false pulse on power-up and continuous overload or short circuit of outputs
Output Response Time LX3: 0.8 ms ON-time; 6 ms OFF-time (5 ms OFF-delay) LX15: 4.0 ms ON-time; 9 ms OFF-time (5 ms OFF-delay)
LX6: 1.6 ms ON-time; 7 ms OFF-time (5 ms OFF-delay) LX18: 4.8 ms ON-time; 10 ms OFF-time (5 ms OFF-delay)
LX9: 2.4 ms ON-time; 7.5 ms OFF-time (5 ms OFF-delay) LX21: 5.6 ms ON-time; 11 ms OFF-time (5 ms OFF-delay)
LX12: 3.2 ms ON-time; 8.5 ms OFF-time (5 ms OFF-delay) LX24: 6.4 ms ON-time; 11.5 ms OFF-time (5 ms OFF-delay)
Minimum Object Detection
Size (M.O.D.S.)
Smallest diameter rod that can be detected in sensing range: Short-Range: 5.6 mm (0.22")
Standard-Range: 9.5 mm (0.38")
Indicators Emitter: LED1 (green) LED2 (red)
ON: Power ON, good sensor ON: Reduced range
OFF: Reduced Range OFF: Normal range
Flashing: Emitter hardware failure
Receiver: LED1 (yellow) LED2 (bicolor green/red)
ON: Output conducting Green: Normal range
OFF: Output not conducting Red: Reduced range
Flashing Red: Receiver hardware failure
Construction Aluminum housing, die cast zinc with black e-coat painted endcaps, acrylic lens window
Environmental Rating Meets IEC IP65
Connections 2 meter (6.5') 5-conductor (with drain) pvc-jacketed attached cable or 5-pin Euro-style 150 mm (6") QD pigtail,
depending on model
Operating Conditions Temperature: -20° to +70° C (-4° to +158° F)
Max. rel. humidity: 90% at 50° C (non-condensing)
Application Notes i) The best sensing resolution occurs within the center 80% of the sensing range (see Figure 1).
ii) Low-profile packages can be reliably detected.
iii) Outputs are active while the light screen is interrupted.
iv) For reliable detection, successive parts must be spaced up to the total of ON-time plus OFF-time apart.
(ie: 12 milliseconds for the LX12)
