With a slim rectangular body and rugged enclosure, it provides secure switching performance while simplifying installation in tight or demanding spaces. The RE23-SA64 offers dual safety outputs, a generous sensing range, and a durable build—solving the common issue of maintaining reliable guard monitoring over long operational cycles.
The SICK RE23-SA64 enhances safety system reliability by combining long-life reed contact technology with a design optimized for robust industrial use. Its consistent switching behavior, even from multiple approach angles, ensures dependable performance where doors or covers may not align perfectly every time. The unit’s reinforced housing material withstands mechanical stress and temperature fluctuations, reducing the need for maintenance or replacement. When used with modern safety controllers, it supports advanced diagnostics and streamlined wiring layouts. This switch ultimately boosts machine uptime, helps maintain compliance with safety standards, and offers a straightforward solution for facilities seeking reliable, low-maintenance access protection.
The SICK RE23-SA64 is ideal for engineers who need a compact, rugged, and non-contact safety switch that performs reliably even when machines vibrate, shift, or experience dust buildup. Its magnetic technology ensures consistent activation without mechanical wear, making it a long-lasting safety component that keeps equipment compliant, stable, and efficient in daily industrial operation.
The RE23-SA64 solves the recurring challenge of unreliable guard monitoring caused by misaligned doors, worn mechanical switches, or harsh environmental conditions. By using magnetic sensing with multiple approach tolerances, it eliminates false trips, reduces maintenance effort, and ensures machines remain safely supervised—ultimately improving uptime and operational confidence across demanding production environments.

Food packaging machines often run at high speed, with sealing components and moving belts close to operator access points. These environments experience frequent washdowns and exposure to fine powders, which can cause mechanical switches to clog or stick. A magnetic non-contact switch such as the RE23-SA64 avoids these issues because it senses position without requiring physical contact. Even if doors shift slightly due to vibration or repeated opening, the switch maintains stable detection. This ensures the safety circuit stays reliable while allowing production to continue without constant readjustments. As a result, operators stay protected and machine uptime remains consistently high.
Automated distribution facilities use long conveyor networks equipped with swing gates for clearing jams and performing maintenance. These gates often experience vibration from heavy load movement and may not always return to the exact same closing position. The RE23-SA64’s magnetic sensing ability makes it ideal for such conditions, offering accurate detection even when alignment is not perfect. Since the switch does not rely on physical contact, it resists wear from frequent cycling throughout long shifts. Technicians benefit from its clear LED status indicators, which simplify troubleshooting. This contributes to smoother conveyor operation and reduces downtime in fast-moving warehouse environments.
CNC machining centers require dependable door monitoring to protect workers from rotating tools, flying chips, and coolant spray. Sliding machine doors frequently experience shock loads and small positional changes that can cause mechanical switches to fail or misread. A magnetic safety switch overcomes these challenges by allowing a wider tolerance for door positioning while still providing precise switch-on and switch-off behavior. The RE23-SA64’s rugged housing resists oil, vibration, and metal debris commonly found in machining workshops. Its consistent activation helps ensure the machine only operates when the enclosure is properly closed, supporting both safety compliance and production efficiency.
Robot cells often feature multiple access points used by technicians for tool adjustments, part fixture changes, or routine calibration. Hinges and fence panels in these areas gradually loosen over time, making perfect alignment difficult to maintain. A magnetic non-contact switch provides a reliable solution by functioning correctly even when the door position drifts slightly. The RE23-SA64’s stable sensing range and durable construction support continuous operation in environments exposed to vibration and temperature changes. When integrated with advanced safety controllers, it also enables efficient monitoring of multiple doors. This helps keep robot systems running safely while minimizing interruptions to maintenance workflows.
