Reliable SICK RE13-SA03 magnetic safety switch for precise guard monitoring. Wear-free, compact, and built for industrial safety applications with long service life.
The SICK RE13-SA03 non-contact magnetic safety switch is designed for machine builders who require reliable guard monitoring without the wear and tear of mechanical actuators. Its magnetic sensing technology enables consistent switching performance while allowing greater tolerance for misalignment, making it suitable for sliding, hinged, or removable guards. With two independent N/O safety channels and a rugged, compact housing, the RE13-SA03 offers safe operation even in environments exposed to dust, vibration, or washing processes. The switch is engineered to help reduce maintenance downtime and enhance operator protection for a wide range of industrial machines.
The RE13-SA03 integrates magnetic actuation with assured switching distances to support stable performance over long operating cycles. Its ability to function across five approach directions provides installation freedom, especially where precise alignment is difficult. The enclosure, built from durable engineering material and rated to IP67, ensures dependable operation in demanding settings where moisture or shock may occur. When paired with a certified safety controller, the switch contributes to achieving required safety performance levels without relying on internal fault detection. This makes it a practical choice for packaging systems, automated handling equipment, and industrial enclosures that need long service life with minimal mechanical stress.
The RE13-SA03 is ideal for engineers who need a safety switch that keeps performing even when machines vibrate, shift, or experience frequent movements. Its magnetic operation eliminates mechanical wear, while its compact housing fits into tight guard areas. It delivers dependable switching distances, simple integration, and robust durability—making it a long-lasting safety component for modern automated systems.
The RE13-SA03 solves the challenge of unreliable door or guard monitoring where mechanical switches often fail due to misalignment, dust, or continuous motion. By using a non-contact magnetic principle, it maintains consistent detection without friction or deformation. This reduces unexpected stoppages, strengthens operator safety, and ensures machines stay compliant, efficient, and easier to maintain over time.

Packaging machines often operate at high cycle rates, with frequent stops for clearing jams, replenishing materials, or routine adjustments. A magnetic non-contact safety switch helps ensure the machine only runs when the guard is fully closed, even if the door shifts slightly over time. Because the switch tolerates misalignment and has no moving parts, it works reliably in areas filled with dust, vibration, and constant operator interaction. This reduces unexpected stoppages, prevents access to moving components, and supports safer operation in busy production lines where uptime and worker safety must coexist.
Machine shops rely on strong enclosures to shield operators from rotating tools, flying chips, and coolant spray. A magnetic safety switch provides dependable confirmation that the machine door is secured before cutting operations begin. Its non-contact nature avoids failure caused by chips, oil, or repeated opening cycles. Even when the door rails or hinges loosen slightly, the wide switching distance ensures consistent detection. This helps keep high-speed equipment from starting unintentionally and supports compliance with guarding requirements, while allowing operators to maintain smooth workflow during tool changes and part setup.
Industrial robots frequently work in enclosed cells where human access must be strictly controlled. A magnetic non-contact switch is used on the main entry gate to verify that the barrier is fully closed before robotic motion resumes. The switch maintains accuracy even in applications with regular vibration or cage distortion caused by heavy equipment. Redundant safety contacts further reduce the chance of false signals. This creates a dependable safety layer that prevents unintentional robot startup during inspection or loading, enhancing the overall safety performance of automated cells without slowing down productivity.
Facilities such as food processing plants, woodworking lines, and general assembly areas often expose safety devices to dust, moisture, or routine cleaning. A sealed non-contact magnetic switch avoids the mechanical sticking or corrosion issues seen in traditional switches. Its IP-rated enclosure allows it to survive washdowns, while the absence of physical contact eliminates wear from repeated use. Even when surfaces become dirty or slightly misaligned, the switch continues to detect guard positioning reliably. This ensures machines operate only under safe conditions while minimizing the maintenance required in challenging environments.
