Datasheet
Miniature self-contained photoelectric sensors in universal housing
• Bright, visible red (640 nm) light source
• Standard models available with 4-wire 2 m (6.5 ft) or 9 m (30 ft) cable or 3 or 4-
wire 150 mm (6 in) pigtail with Pico-style M8 threaded connector
• Solid-state, bipolar outputs: one current sourcing (PNP) and one current
sinking (NPN) standard on 4-wire models
• Single output solid-state PNP or NPN standard on Q3 models
• Light Operate (L.O.) or Dark Operate (D.O.), depending on model
• Models available with PFA chemical-resistant jacket (1200 psi washdown
rated) for use in harsh environments
• Compact 8 mm (0.31 in) housing mounts almost anywhere
• Crosstalk avoidance circuitry for applications with multiple sensors
• LED status indicators for Power ON, Output Overload, Signal Received, and
Marginal Signal
• Models with black housing are available

WARNING:
• Do not use this device for personnel protection
• Using this device for personnel protection could result in serious injury or death.
• This device does not include the self-checking redundant circuitry necessary to allow its use in
personnel safety applications. A device failure or malfunction can cause either an energized (on) or de-
energized (off) output condition.
