The LCMF1584-R4N2V vehicle separation measurement grating is a simple and easy-to-use two-piece measurement grating designed for shape detection, object detection, and vehicle separation applications; The LCMF1584-R4N2V vehicle separation measurement grating can automatically detect transmitter and receiver failures, as well as lens contamination status; Can continue to work in a failed state while issuing an alarm. The diagnostic LED indicator light can display the working status and fault status of the light curtain; Using a unique algorithm, the light curtain only detects objects larger than 150mm and has a resolution of 17.5mm, which can reliably detect the position of the vehicle hook; The height of the light curtain is 181mm~2.4m; The beam spacing is available in two specifications: 15mm and 30mm; Dual switch output and RS485 serial communication output; The RS485 serial communication function can process scanned data and system status through a computer; The system can be set up through the RS485 serial port interface; Alarm output can indicate system faults or lens contamination status; Dual switch output, customers can customize according to their requirements. (N-type, P-type, bright on, dark on).
