Compact SICK RE13-SA84 magnetic safety switch for reliable non-contact guard monitoring. Durable design, wide sensing tolerance, and stable performance in harsh environments.
The SICK RE13-SA84 magnetic non-contact safety switch is built for dependable guard monitoring in compact machines and industrial equipment where mechanical switches often struggle. Using magnetic actuation, it eliminates wear from repeated opening and closing, helping maintain consistent performance over long periods. Its VISTAL® housing keeps it lightweight yet durable, while the switch-on and switch-off distances give it tolerance to misalignment, reducing nuisance downtime. With two normally open safety outputs and a rugged IP67 rating, the RE13-SA84 provides stable detection even in areas exposed to shock, vibration, dust, or moisture.
The RE13-SA84 is designed to improve machine safety by sensing door or guard positions without requiring physical contact, making it ideal where maintenance access is frequent. Its magnetic sensing method ensures reliable activation even when alignment is imperfect. The integrated cable with M8 connector simplifies installation, while the wide operating temperature range supports use in both chilled and warm production environments. Because the switch handles environmental challenges and movement well, it suits fast-paced machinery where consistent stop/start monitoring is essential. Manufacturers benefit from a long service life, reduced mechanical failures, and stable safety feedback across daily operations.
The SICK RE13-SA84 is chosen for its ability to deliver reliable guard monitoring without mechanical wear or complex alignment demands. Its magnetic sensing design thrives in environments where vibration, dust, or frequent door operation would quickly degrade conventional switches. With its slim structure and rugged build, it offers long-term safety performance in equipment where stability and space efficiency are critical.
The RE13-SA84 eliminates the recurring issues of false trips, damaged hinges, and misaligned switches commonly seen in mechanical interlocks. It ensures machines receive consistent safety feedback even when doors shift slightly, or conditions fluctuate. By removing physical contact from the sensing process, it reduces maintenance interruptions and enhances operational continuity across varied industrial setups.

Packaging machines often have small access doors that operators open constantly for label-roll changes, cleaning, or clearing material jams. Traditional mechanical switches lose accuracy over time because hinges shift or operators close the door slightly off-center. A magnetic non-contact switch eliminates this dependency on perfect alignment, allowing the machine to detect door status even when panels move slightly due to vibration or daily wear. The extended sensing distance helps the equipment restart quickly after maintenance, and the sealed housing prevents dust from affecting performance. This makes the system more reliable, reduces unplanned downtime, and supports smooth workflow on busy packaging lines.
Conveyors used in food environments must be washed frequently, which means guards are taken on and off many times during a single shift. Moisture, cleaning agents, and temperature swings often cause mechanical switches to corrode or stick, creating unreliable safety signals. A magnetic non-contact switch performs better here because it is completely sealed and continues to sense through small gaps even when panels are not perfectly aligned after cleaning. The consistent detection helps ensure the conveyor only runs when shields are truly secured. This improves both hygiene operations and overall equipment safety, while lowering maintenance effort in areas exposed to daily washdowns.
Modern warehouse lift systems include tall enclosures and narrow service panels that must be monitored for safe operation. These systems generate frequent vibration and rapid movements that can cause mechanical switches to misread whether a panel is closed. A magnetic non-contact switch provides a steadier signal because it is unaffected by these small shifts. Its sensing tolerance allows movement of the metal frame without losing detection accuracy. Maintenance staff also appreciate the compact housing, which fits neatly within slim support structures. This results in more reliable guard supervision and helps the automated system continue running smoothly during busy warehouse cycles.
CNC machines generate heat, coolant spray, and continuous vibration, all of which can cause sliding shields to drift slightly over time. Mechanical switches positioned on these covers often suffer misalignment or clog with debris, leading to unnecessary stoppages. A magnetic non-contact switch avoids these issues because it does not require physical contact and continues to detect accurately even when the shield shifts. The robust enclosure resists coolant exposure, and the generous activation distance supports older machines where panel fit may not be perfect. This provides operators with stable machine readiness, reduces false alarms, and enhances long-term reliability in demanding machining environments.
