Safety Sensors

• Coded – receiver accepts any PSENcode actuator.
• Fully coded – receiver only accepts one actuator and can be retaught 8 times.
• Uniquely coded – receiver accepts only one actuator and can be retaught once.

Mechanical safety switches with spring interlocks are interlocked when there is no power applied to the coil. This is safe guard locking.

For mechanical safety switches with a magnetic interlock, the interlock is active when power is applied to the coil. This is process guard locking.

The muting function guarantees the safety function is automatically enabled over all or part of the height of the protected field, to enable specific, cyclical work operations to be carried out without having to stop the machine operation.

5m, 10 and 110 degrees. The 5m can be split into 4 zones.

Radar is the only technology that can be relied on 100% of the time in all-weather conditions, meaning safety and availability can be guaranteed. This is essential if autonomous solutions are to be as good as or better than their human counterparts. The Navtech Radar sensor is a field-tested solution that works today and will continue to work for the next 10 years in some of the harshest industrial settings on earth.

The number of radars required, and the radar model, depends on the context. While we can make estimates based on maps and drawings, an accurate site design can only be made following a site survey. We use an online planning tool for the initial estimates and the designs can be shared with customers to visualise how a site would be covered with different radar models.

Radar resolution is defined by the frequency bandwidth and wavelength of the radar signal. The smaller the wavelength, the better the range resolution. We operate in the millimetre range, meaning our sensors are high-resolution.

Yes, the radar is ROS compatible. Within the Software Development Kit SDK there is an example ROS application to get a project started. This includes publishing radar data as a pointcloud, laserscan and object identification options.

The radar beam is not a pencil beam-like a laser, but has a 3D profile with this in mind. It is more like a touchlight than a laser. Since the radar returns a value from every range measurement, it can see through noisy objects, something that most time-of-flight sensors can’t.

By “seeing” past the first detection the radar is unlike a lidar. By splitting each azimuth into an array of radially spaced intensity values the radar provides an extra dimension that a lidar can’t. This enables the radar to build up top-down “photo”-like images – something a lidar unit can’t do without implementing multiple channels.

Another crucial difference between the Navtech Radar and a lidar is its ability to work through adverse weather conditions. The longer wavelength of the radar signal is not affected by dust, fog, rain or snow , so the sensor can be used in all scenarios, giving it a large operating window. And, because it doesn’t have a lens it doesn’t require cleaning.
