Robot cells and large machine tools are dangerous, which is why safeguarding these spaces is essential. Many facilities install equipment interlocks to increase safety, but operator tampering and complex wiring requirements can make these devices unreliable. To prevent tampering and simplify installation, each Omron D41D is uniquely coded. They also comply with IEC 61508 (Safety), ISO 14119 (Type 4/High Coded), and ISO 13849-1 (PLe). With its rugged design, the D41D is well suited for machine enclosures and robot cells.
