Overview
The Banner Q23SP6LPQ photoelectric sensor is a polarized retroreflective unit designed for precise object detection in industrial automation environments. This compact sensor delivers reliable presence/absence detection with a visible red sensing beam, making alignment and setup straightforward. The Q23SP6LPQ features complementary PNP outputs and operates across 10–30 VDC supply voltages, supporting both light-on and dark-on operational modes.
Key Features
- Retroreflective Sensing: Detects objects with a built-in reflector, ideal for detecting clear containers, translucent materials, and complex surfaces
- Visible Red Laser Beam: 680 nm red sensing beam aids quick alignment and troubleshooting without tools
- Dual PNP Outputs: Complementary normally-open and normally-closed outputs enable flexible logic integration
- Self-Diagnostic Circuitry: Built-in LED indicators show power status, output condition, alignment, and marginal signal warnings
- Compact IP67 Housing: Sealed ABS thermoplastic enclosure rated for harsh industrial environments (NEMA 1/2/3/3S/4/4X/6/12/13)
- 1 ms Response Time: Fast switching enables high-speed line applications

Replaces / Drop-In Replacement For
The Banner Q23SP6LPQ has been discontinued by the manufacturer and is officially replaced by the Q20PLPQ model. While legacy systems may still use the Q23SP6LPQ, new installations should reference the Q20PLPQ as the current-generation equivalent. Always verify output voltage and connector type when substituting sensors in existing circuits.
Works With
- Studio 5000 (Allen-Bradley) via analog input modules
- TIA Portal (Siemens) PLC programming environments
- 24 VDC industrial relay logic and contactor circuits
- Discrete I/O wiring in legacy control cabinets
- Modbus and Profibus gateways for networked applications
