The IDEC SE2L safety laser scanner is the smallest in the world, while outperforming most of the competition. Features include a 270-degree sensing angle, a 5m safety protection zone, a 20m warning zone and customizable protection patterns. 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-degree protection for an AGV, which requires four scanners. SE2L can cover long distances, which makes it ideal for use with a variety of industrial robots and machinery. With dual protection mode, SE2L can also be programmed to safeguard two different zones for two robots at once. This can reduce the number of laser scanners and light curtains by half.
Ensures the safety of humans in a hazardous area, or those approaching the machine.
One SE2L protects a wide area (270º and 5m) and can be used in a variety of applications such as large sized systems or long conveyor lines.

The SE2L is a safety sensor that can detect approach. Stop area can be made smaller by detecting approach at the additional protection zone to start slowdown.
(Conventional configuration of one protection zone + two warning zones is possible)
A maximum of four SE2Ls can be interconnected using RS-485 for master/slave operation.
Access Protection
Allows only objects to pass through. Detects the access of humans.
An SE2L can monitor two separate hazardous areas to stop machines when detecting the access of humans. No reflective sensor is necessary, thus eliminating the need of optical axis alignment. Can replace two light curtains.
Reference monitoring function ensures safety by detecting the positional change of SE2L or reference boundary, such as a door’s opening/closing status.
Collision Avoidance
Protects humans from colliding. Also prevents loads on from falling.
A maximum of 128* area patterns can be configured/switched according to the mobile application such as AGV, ensuring the optimum protection in various applications.
*Maximum 32 sets of area can be configured by parallel input when switching the area by encoder input.
During safety protection, the SE2L can send out distance measurement data through the Ethernet port, in order to obtain the data of the obstacles.
Excellent Usability
Easy-to-use configuration and useful functions for simple and comfortable maintenance.
Teaching function enables automatic area configuration by referring to obstacles such as walls and columns. Area can be configured easily even with complicated background.
Area data and distance measurement data can be recorded while monitoring on PC. Video of detection status can be replayed with the file.
The measured data can be recorded few seconds (arbitrary) before or after detection.
Robot controller connection terminal (accessory)
During safety protection, the SE2L can send out distance measurement data through the Ethernet port, in order to obtain the data of the obstacles.
The connection terminal allows the safety signal from the safety laser scanner to be easily input to the robot controller. The safety signal is converted and output as a dry contact output of a force-guided relay. Two sets of dual signals can be output.
