Overview
The Banner Q20E-78017 is a rectangular photoelectric emitter from Banner Engineering’s World-Beam Q20 series. Designed for opposed-mode (through-beam) sensing, this compact sensor delivers reliable detection at ranges up to 12 meters. The visible red light (624nm) and sealed thermoplastic housing make it ideal for manufacturing, packaging, and automation applications where durability and consistent performance are critical.
Key Features
- 12-meter sensing range — sufficient for most industrial through-beam applications
- Visible red light (624nm) — aids alignment and troubleshooting during installation
- IP67/NEMA 6 rating — sealed against dust and moisture ingress
- 4-wire cable termination — pre-wired with 6.5 ft (2 m) cable and bare-end flying leads
- Thermoplastic housing — durable construction rated for -20°C to +60°C ambient operation
- Rectangular compact form factor — space-efficient mounting in confined spaces
