SE2L Safety Laser Scanner

IDEC Corporation's SE2L safety laser scanner is currently the world’s smallest, and is the world’s first with master/slave functionality and dual protection zones. A laser scanner is a safety device that uses the reflection of laser beams to detect the presence of objects or people. The scanner is certified for use in safety applications including automated guided vehicles (AGVs), forklifts, robots, and other items of moving equipment found in industrial facilities. Master/slave functionality allows one SE2L scanner to act as master and communicate with up to three other scanners. The safety controller only needs to communicate with the master, reducing the required number of input and communication channels on the controller. This can allow lower-cost controllers to be applied in applications such as providing full 360° protection for an AGV, which requires four scanners.

Dual-zone protection allows one SE2L scanner to scan two adjacent zones simultaneously and independently, performing the work of two scanners for the cost of one. The scanner provides a standard 270° arc of protection at a distance up to 20 meters, and this protection area can be configured into any pattern using either free programming software provided with the scanner, or with the scanner’s teach mode. The software provides drop-and-drag functionality to configure the protection area into any pattern within its 270° arc of protection. The teach mode scans obstructions in its standard 270° arc of protection to produce a pattern. Up to 32 patterns can be stored in the scanner.

The scanner communicates intrusion alerts to a safety controller via four PNP OSSD safety outputs and two PNP non-safety outputs. The OSSD outputs have a self-diagnosis function that tests the signal periodically to detect malfunction. The scanner is configured using IDEC’s SLS Project Designer Software, which can be downloaded for free. Once the configuration is complete, it can be downloaded to the scanner through its Micro USB port or Micro SD Card slot.

The scanner is certified for use in Safety Category 3, Performance Level d (PLd), Safety Integrity Level 2 (SIL2) applications. It is housed in an IP65 enclosure. In addition to performing its certified safety functions, the scanner can also be used to make highly accurate distance measurements, communicating this information through its Ethernet port to a controller or a PC. It can also be used to measure speed through its incremental encoder input which measures pulses.
