Banner Engineering QS18VP6LV WORLD-BEAM Retro Sensor, 6.5m Range, 10-30V DC, PNP Output, 2m Cable

The sensor provides a complementary solid-state PNP (sourcing) output. It is a 4-wire device: typically, brown wire is +V (10-30V DC), blue wire is 0V common, black wire is the PNP output signal, and white wire is for output mode selection (light/dark operate). The output switches to the supply voltage level when activated.

Non-polarized retroreflective mode means the sensor uses a standard reflector and is not filtered to ignore light from shiny surfaces. It detects the interruption of its own beam reflected from a dedicated reflector. This mode is reliable but can be triggered by highly reflective objects, making it best used with standard retro-reflector targets.

Yes, the QS18VP6LV is rated IP67 and NEMA 4X, making it dust-tight and capable of withstanding temporary immersion in water up to 1 meter for 30 minutes. Its ABS housing and acrylic lens are also resistant to corrosion, making it suitable for damp, dusty, and washdown industrial environments.

This feature allows you to invert the sensor's logic. In 'light operate' mode, the output activates when the beam is received (target absent). In 'dark operate' mode, the output activates when the beam is blocked (target present). This flexibility lets you match the sensor's logic to your control system's requirements.

The response time is 0.6 milliseconds. This fast switching speed is critical for high-speed applications like counting small objects on a fast-moving conveyor, detecting parts in rapid assembly lines, or providing precise timing signals in automated machinery without missing events.
