Q4XTILAF500-Q8 Laser Distance Sensor
The Q4XTILAF500-Q8 is a high-performance laser range sensor from the Q4X series, utilizing time-of-flight (TOF) technology for non-contact distance measurement. It provides a linear analog output (4-20 mA) proportional to the target distance, as well as a discrete switching output. The sensor is designed for challenging industrial environments including dusty, oily, or high-contrast target surfaces.
Measurement and Performance
Measurement range: 50 mm to 500 mm. Resolution: 1 mm. Accuracy: ±3 mm over full scale. Response time: 2 ms (adjustable up to 100 ms for stability). The 655 nm visible red laser (Class 2,<1 mW) provides a visible spot size of 3 mm at 500 mm, simplifying alignment. The sensor can detect targets with reflectivity from 6% (black matte) to 90% (white glossy) without manual gain adjustment.
Outputs and Configuration
The Q8 connector (M12, 4-pin) provides power (10-30 V DC) and two outputs: Output 1 is the analog output (4-20 mA, load max 300 Ω), and Output 2 is an NPN/PNP switching output (sink/source selectable, 100 mA). The sensor can be configured via two teach buttons or remote teach input. Three operating modes: standard distance measurement, window comparator, and background suppression. An integrated OLED display shows real-time distance or % of range.
Environmental Resistance
IP67 and IP69K rated housing (stainless steel sensing face, ABS plastic body). Operating temperature: -30°C to +70°C. The sensor resists cleaning chemicals, oils, and coolants. Vibration resistance: 20 g (10-2000 Hz). Shock: 100 g. Auto-adjusting laser power compensates for window contamination. An internal heating element prevents lens fogging in cold environments.
Typical Applications
Used in automotive assembly for part presence verification, robotic end-of-arm tooling for pick-and-place positioning, and tank level monitoring. The analog output can directly feed a PLC analog input for continuous level control in filling machines. The discrete output can act as a go/no-go gauge for quality sorting.
Installation and Alignment
Mount using two M4 screws (provided). A visible red dot simplifies aiming at the target. The sensor’s cross-hair reticle in the display helps fine-tune alignment. For reflective or shiny targets, a 15-degree tilt is recommended to avoid specular reflection.
