SICK RZC1-04ZRS-KU0 Cylinder Sensor with IP69K Protection
The SICK RZC1-04ZRS-KU0 cylinder sensor with IP69K protection is a compact and robust solution for detecting piston positions in pneumatic cylinders with C-slot designs. Built around reliable reed switching technology, it provides stable and repeatable signals even in high-speed operations. Its short housing length supports installation in tight mechanical layouts, while the sealed construction withstands moisture, dust, and aggressive cleaning processes. This sensor is designed to solve common reliability issues found in harsh industrial environments where standard cylinder sensors fail prematurely.
The SICK RZC1-04ZRS-KU0 is engineered for applications that demand consistent cylinder feedback under demanding conditions. The broad AC/DC supply range allows easy connection to various control systems without additional interface components. High switching accuracy and resistance to vibration help prevent false signals, improving machine reliability and process stability. Its ability to operate across wide temperature ranges makes it suitable for packaging lines, automated assembly, and washdown-prone machinery, reducing downtime and maintenance while ensuring precise motion control.
Why SICK RZC1-04ZRS-KU0?
The SICK RZC1-04ZRS-KU0 is chosen when reliability, compactness, and environmental resistance are non-negotiable. It combines a slim mechanical design with proven reed switch technology to deliver consistent cylinder position detection, even in fast and repetitive motion cycles. Designed for demanding industrial conditions, it tolerates vibration, temperature extremes, and intensive washdown processes. This makes it an ideal solution for engineers who want a “fit-and-forget” sensor that integrates easily, reduces commissioning effort, and continues to perform accurately throughout the machine’s service life.
What Problem Does It Solve?
The SICK RZC1-04ZRS-KU0 solves the challenge of unreliable cylinder position feedback in harsh or space-limited applications. In many machines, moisture ingress, mechanical shock, or unstable signals lead to false switching, downtime, and increased maintenance. This sensor provides stable, repeatable detection of piston movement, even at high switching speeds, ensuring precise end-position monitoring. By maintaining accurate feedback under demanding conditions, it helps prevent process errors, improves machine availability, and supports consistent, predictable automation performance.

The Applications
1. End-Position Detection for Rapid Pneumatic Motion
In modern packaging lines, pneumatic cylinders cycle continuously to seal, cut, and index products at high speed. The SICK RZC1-04ZRS-KU0 is installed in the cylinder slot to confirm precise end positions before each process step proceeds. Its reed-based switching supports fast response without unstable signals, even during frequent movements. The compact sensor body fits neatly into dense machine layouts, while the sealed housing tolerates cleaning and moisture exposure. This combination allows packaging equipment to run at high throughput with reliable position feedback and reduced risk of cycle errors.
2. Position Verification for Fixtures and Clamping Units
Automated assembly cells depend on pneumatic clamps to hold parts securely during machining or joining operations. The SICK RZC1-04ZRS-KU0 monitors whether clamps have reached their fully open or closed positions before robots or tools engage. High reproducibility ensures consistent detection across long production runs, reducing alignment issues and part damage. Its resistance to vibration allows reliable operation near moving robots and presses. By delivering dependable cylinder feedback, the sensor supports precise sequencing, improves product quality, and helps maintain safe, repeatable assembly processes.
3. Cylinder Position Feedback in Hygienic Equipment
Food and beverage production equipment is regularly exposed to water, detergents, and temperature changes. In these environments, the SICK RZC1-04ZRS-KU0 monitors pneumatic cylinders used in filling, capping, and product transfer systems. The robust sealing protects internal components during intensive cleaning routines, while stable switching ensures accurate motion detection. Reliable cylinder feedback prevents incomplete strokes that could disrupt production or compromise hygiene. As a result, manufacturers benefit from consistent operation, fewer sensor failures, and reduced maintenance in washdown-prone processing areas.
4. Position Detection for Conveyors and Diverters
In logistics and material handling applications, pneumatic actuators control diverters, stops, and lifting mechanisms. The SICK RZC1-04ZRS-KU0 confirms actuator positions before loads are redirected or transferred. Its tolerance to dust, vibration, and temperature variation makes it suitable for warehouses and distribution centers. The defined sensing behavior helps absorb minor speed variations without false signals, ensuring accurate system logic. This reliable position feedback reduces jams, prevents collisions, and supports smooth, continuous material flow in demanding handling operations.
