Description
Omron STI MA-11DP20C3 Non-Contact Safety Switch & Actuator IP67 NC
The Omron STI MA-11DP20C3 is a non-contact magnetic safety interlock switch and actuator set designed for machine guard door monitoring in industrial automation environments. The switch uses magnetic actuation — no physical contact between switch and actuator — allowing for misalignment tolerance up to 10 mm and an extended mechanical service life. The MA-11DP20C3 is the DC variant, featuring two normally-closed (NC) safety contacts and a pre-wired 5-meter 4-core cable for direct installation.

Applications
The STI MA-11 series is used for safety interlocking of guard doors, access panels, and protective enclosures on industrial machinery. Non-contact magnetic switches are common in machine guarding systems where door or panel position must be monitored to meet safety category requirements (EN ISO 13849, IEC 62061). They are found in packaging lines, CNC machine tools, robotic cells, and general factory automation where a wear-free, IP67-rated interlock is required.
