Page 11: Theory Of Operation
Theory of Operation Theory of Operation This section gives a brief overview about the theory of operation. Operation of the Triangulation Sensor A triangulation sensor measures objects by imaging the intersection of a uniform planar light source and an object. The sensor projects a sheet of light through a measurement area. - Page 12 Theory of Operation Number Element In-Sight 3D-L4000 Laser plane Inspected object Camera field of view Working section Laser stripe The vision system (1) projects a triangular laser plane (2) onto the object under inspection (3), illuminating the object's surface. The illumination of the laser plane determines the peak data of the raw 2D image and results in the 3D-L4000's laser stripe (6) within its field of view (4).
-
Page 13: Point Cloud
Theory of Operation The vision system then applies an algorithm to find the peaks to extract the uncalibrated peak data. On the image below, the cyan blue lines represent a subregion of the field of view working section (see Working Distances and Fields of View page 10), where the vision system is looking for peak data. -
Page 14: Invisible Points
Theory of Operation These profiles are assembled to create an image of the whole object. This is called a point cloud. The image below shows an example. Invisible Points As the vision system views the object at a fixed angle from the laser plane, certain areas of the object under inspection may be hidden from the vision system. - Page 15 Theory of Operation The orange stripe shows the width of the lower red stripe, relative to the upper red stripe. The green portions show the difference between the two widths. Consider a Lego® block scanned by the vision system. As it passes under the camera, the laser stripe appears for each step.

Installation Mount the Vision System: Top Housing 1. Align the holes on the mounting surface with the mounting holes on the vision system. 2. Insert the M4 screws into the top mounting holes and tighten. The maximum torque is 2.00Nm (17.70in-lb). Do not exceed the maximum insertion depth of 8 mm for the M4 screws. -
Page 18: Mount The Vision System: Rear Housing
Installation Mount the Vision System: Rear Housing 1. Align the holes on the mounting surface with the mounting holes on the vision system. 2. Insert the M5 screws into the rear mounting holes and tighten. The maximum torque is 3.00 Nm (26.55 in-lb). Do not exceed the maximum insertion depth of 8 mm for the M5 screws.. -
Page 19: Connect The Ethernet Cable
Installation Connect the Ethernet Cable CAUTION: The Ethernet cable shield must be grounded at the far end. Whatever this cable is plugged into (typically a switch or router) should have a grounded Ethernet connector. A digital voltmeter should be used to validate the grounding. -
Page 20: Connect The Breakout Cable
24 VDC supply, the encoder supply and the 24 VDC supply need to have a common GND connection. Cognex recommends to ground unused encoder connections. If you configure the In-Sight 3D software to use an encoder but do no connect the encoder signal inputs, the behavior of the encoder counter is undetermined. - Page 21 Installation When the vision system is on, the Power LED on top of the unit will light up green.

Page 22: Cleaning And Maintenance
CAUTION: Use care not to damage the anti-reflective coating on the windows. Cognex makes the following recommendations for cleaning the laser and vision system windows: Unplug the unit so the laser cannot be enabled. Use lint-free tissue or an optical grade cotton swab ("Q-tip"). -

Page 28: Encoder Inputs
Vision System Specifications A quadrature rotary encoder uses two output channels (A and B) to provide cyclical outputs as the encoder rotates. The signals are quadrature outputs - 90 degrees out of phase with each other. Each complete quadrature cycle consists of four rising or falling pulse edges. -
Page 29: Encoder Wiring
Vision System Specifications Note: If you are using a Single-Channel Encoder, always connect to the ‘PHA’ input. WARNING: The frequency of pulses has to remain under 1000 kHz. Single-ended encoders use one wire each for signals A and B. Be aware single-ended encoders are susceptible to electrical noise. -
Page 30: Trigger And Laser Enable Inputs
Vision System Specifications Trigger and Laser Enable Inputs The acquisition trigger and laser enable inputs to the sensor are opto-isolated. The sensor responds to a trigger event when the voltage difference between the TRIGGER and IN COMMON inputs exceed 10 V. The laser enable input is enabled when the difference between the LASER ENABLE and IN COMMON inputs exceed 10 V. -

Vision System Specifications Trigger and Laser Enable Wiring Number Component Trigger (Sensor Sinks Current - NPN) Laser Enable (Sensor Sinks Current - NPN) Number Component Trigger (Sensor Sources Current - PNP) Laser Enable (Sensor Sources Current- PNP) Outputs The optically isolated outputs are usable as either NPN ( current sinking, pull-down) or PNP (current sourcing, pull-up) lines. -
Page 32: Output Wiring
Vision System Specifications In case of PNP lines, the external load is connected between the output and the negative supply voltage (0 V). When connected to a 24 VDC power supply, the outputs pull up greater than 21 V when ON, and current flows through the load. - Page 33 Vision System Specifications The image below presents the wiring schematic of the Output 0 and Output 1 of the PNP (Sensor Sources Current).
