Pilz PSEN rd1.2 radar safety sensor

The Pilz PSEN rd1.2 radar sensor can be used for Cat. 3/PL d and can therefore be used for robot safely applications. When used in conjunction with the PSEN rd1.x I/O PN analysing unit the company says it is easier to incorporate the safe radar system into existing applications. The safe radar system can be used anywhere that optoelectronic sensors reach their limits — particularly in rugged application conditions, such as in woodworking, mineral and steel processing and heavy industry, as well as the transport and logistics sector.

The PSEN rd1.x I/O PN analysing unit in the safe radar system now offers both an Ethernet and a Profisafe interface in addition to the existing interfaces, while the radar sensor is mounted on three axes, so that vertical ceiling installation is also possible due to the rotation around the X- and Y-axis.

It provides an operating range of 5 m as well as a narrow opening angle of 20° vertical or 20–100° horizontal, configurable in 10° increments.

The safety-related functions covered by this system solution include area monitoring, ie, the machine is brought to a safe state as soon as the danger zone is violated. There’s also protection against encroachment behind the protected area. This prevents the machine from restarting automatically if there is still somebody within the danger zone.

The self-teaching background function of the safe radar system can be used to make changes within the warning or protection zones during operation.
