1. General
The LQ-401CL is a 4CMOS line scan camera using four 4096 pixel line sensors mounted on a prism,
for the R, G, B and NIR channels. It operates with an 84 MHz pixel clock, resulting in a maximum
line rate of 18,252 lines per second.
The camera outputs digital data in 4 x 8 bits or 4 x 10 bits format via Camera Link. The camera is
configured by software through the serial communication port of the Camera Link interface, or via
RS-232C through a 12-pin connector.
The camera accepts an M52 mount or F-mount lens, depending on the version selected.
The LQ-401CL is a suitable camera for various applications such as inspection of fruits,
vegetables ,circuits boards or electronic/mechanical parts, as the NIR image can catch scratches or
blemishes on object surfaces which the RGB color image cannot find.
The latest version of the operation manual can be downloaded from www.jai.com .
The latest camera control tool for the LQ-401CL can be downloaded from www.jai.com .

7LED indicator Power, trigger input and operation indications
8 Camera mounting holes 8 x M3, depth 5mm (*3) Note)
*1) Note: Rear protrusion on M52 mount lens must be less than 13mm.
F mount is also available. Rear protrusion for F mount lens is the same as M52 mount.
*2) Note: When a Camera LinkTM cable is connected to the camera, please do not excessively tighten
screws by using a driver. The Camera Link receptacle on the camera might be damaged.
For security, the strength to tighten screws is less than 0.291 Newton meter (Nm).
Tightening by hand is sufficient in order to achieve this.
*3) Note: The depth of mounting hole is 5 mm. If the longer screws than 5 mm are used, they may
damage the circuit board inside.
