CAD models of the rc_visard NG can be downloaded from http://www.roboception.com/download. The CAD models are provided as-is, with no guarantee of correctness. When a material property of aluminum is assigned (density of \(2.76\mathrm{g\over{cm}^3}\)), the mass properties of the CAD model are within 5% of the actual product with respect to weight and center of mass, and within 10% with respect to moment of inertia.

Environmental and operating conditions

The rc_visard NG is designed for industrial applications. Always respect the storage, transport, and operating environmental conditions outlined in Table 3.

Table 3 Environmental conditions
  rc_visard NG
Storage/Transport temperature -25 °C to 70 °C
Operating temperature 0 °C to 50 °C
Relative humidity (non condensing) 20 % to 80 %
Vibration 5 g
Shock 50 g
Protection class IP54
  • Free from corrosive liquids or gases
  • Free from explosive liquids or gases
  • Free from powerful electromagnetic interference

The rc_visard NG is designed for an operating temperature (surrounding environment) of 0 °C to 50 °C and relies on convective (passive) cooling. Unobstructed airflow, especially around the cooling fins, needs to be ensured during use. The rc_visard NG should only be mounted using the provided mechanical mounting interface, and all parts of the housing must remain uncovered. A free space of at least 10 cm extending in all directions from the housing, and sufficient air exchange with the environment is required to ensure adequate cooling. Cooling fins must be free of dirt and other contamination.

The housing temperature depends on the processing load, sensor orientation, and surrounding environmental temperatures. When the sensor’s exposed housing surfaces exceed 60°C, the LED at the front will turn from green to red.


For hand-guided applications, a heat-insulated handle should be attached to the sensor to reduce the risk of burn injuries due to skin exposure to surface temperatures exceeding 60°C.

Power-supply specifications

The rc_visard NG needs to be supplied by a DC voltage source. The rc_visard NG’s standard package doesn’t include a DC power supply. The power supply contained in the connectivity kit may be used for initial setup. For permanent installation, it is the customer’s responsibility to provide suitable DC power. Each rc_visard NG must be connected to a separate power supply. Connection to domestic grid power is only allowed through a power supply certified as EN55011 Class B.

Table 4 Absolute maximum ratings for power supply
  Min Nominal Max
Supply voltage 18.0 V 24 V 30.0 V
Max power consumption     25 W
Overcurrent protection Supply must be fuse-protected to a maximum of 2 A


Exceeding maximum power rating values may lead to damage of the rc_visard NG, power supply, and connected equipment.


A separate power supply must power each rc_visard NG.


Connection to domestic grid power is allowed through a power supply certified as EN55011 Class B only.


Cables are not provided with the rc_visard NG standard package. It is the customer’s responsibility to obtain the proper cabling. Accessories provides an overview of suggested components.


Proper cable management is mandatory. Cabling must always be secured to the rc_visard NG mount with a strain-relief clamp so that no forces due to cable movements are exerted on the rc_visard NG’s M12 connectors. Enough slack needs to be provided to allow for full range of movement of the rc_visard NG without straining the cable. The cable’s minimum bend radius needs to be observed.

The rc_visard NG provides an industrial 8-pin A-coded M12 socket connector for Ethernet connectivity and an 8-pin A-coded M12 plug connector for power and GPIO connectivity. Both connectors are located at the back. The location of both connectors on the rc_visard NG is shown in Fig. 4.


Fig. 4 Locations of the electrical connections for the rc_visard NG, with Ethernet on top and power on the bottom

Connectors are rotated so that standard 90° angled connectors will exit horizontally, away from the camera (away from the cooling fins).


Fig. 5 Pin positions for power and Ethernet connector

Pin assignments for the Ethernet connector are given in Fig. 6.


Fig. 6 Pin assignments for M12 to Ethernet cabling

Pin assignments for the power connector are given in Table 5.

Table 5 Pin assignments for the power connector
Pin Assignment
1 GPIO In 2
2 Power
3 GPIO In 1
4 GPIO Gnd
5 GPIO Vcc
6 GPIO Out 1 (image exposure)
7 Gnd
8 GPIO Out 2

GPIOs are decoupled by photocoupler. GPIO Out 1 by default provides an exposure sync signal with a logic high level for the duration of the image exposure. All GPIOs can be controlled via the IOControl module (IO and Projector Control). Pins of unsused GPIOs should be left floating.


It is especially important that during the boot phase GPIO In 1 is left floating or remains low. The rc_visard NG will not boot if the pin is high during boot time.

GPIO circuitry and specifications are shown in Fig. 7. The maximum rated voltage for GPIO In and GPIO Vcc is 30 V.

Do not connect signals with voltages higher than 30 V to the rc_visard NG.

Mechanical interface

The rc_visard NG offers a mounting-point at the bottom.


Fig. 8 Mounting-point for connecting the rc_visard NG to robots or other mountings

For troubleshooting and static applications, the sensor may be mounted using the standardized tripod thread (UNC 1/4”-20) indicated at the coordinate-frame origin. For dynamic applications such as mounting on a robotic arm, the sensor must be mounted with three M4 (metric standard) 8.8 machine screws tightened to 2.5 Nm and secured with a medium-strength threadlocking adhesive such as Loctite 243. Maximum thread depth is 6 mm. The two 4 mm diameter holes may be used for positioning pins (ISO 2338 4 m6) to ensure precise repositioning of the sensor.


For dynamic applications, the rc_visard NG must be mounted with three M4 8.8 machine screws tightened to 2.5 Nm torque and secured with threadlocking adhesive. Do not use high-strength bolts. The engaged thread depth must be at least 5 mm.

Coordinate frames

The rc_visard NG’s coordinate-frame origin is defined as the exit pupil of the left camera lens. This frame is called sensor coordinate frame or camera coordinate frame. An approximate location for the rc_visard NG is shown in the next image.

The mounting-point frame for the rc_visard NG is defined to be at the bottom, centered in the tripod thread, with orientation identical to that of the sensor’s coordinate frame.

Fig. 9 shows approximate offsets.

The correct offset between the sensor/camera frame and a robot coordinate frame can be calibrated through the hand-eye-calibration procedure.
