DX-R1 Series Non-contact Magnetic Code Safety Switch
The DX-R1 series safety switch features detection confidentiality (providing a unique code), strong anti-interference and high safety / reliability. Using dual-channel safety output technology, it achieves safety level PLe and effectively prevents false alarms, missed alarms or abnormal triggering by humans. It pairs naturally with our safety door latches.
The DX-R1 magnetic-encoding safety switch is designed with multiple magnetic-sensitive elements. These elements must be triggered in a specific sequence for normal operation. The unit is non-contact actuated, has high misalignment tolerance, a large detection range, is easy to install, supports cascade connection in multiple units, and is CE certified — meeting ISO 13849-1 SIL3 / PLe / Category 4.

Key Engineering Advantages
- Non-contact actuation: no mechanical wear at the sensor — long service life and high reliability.
- Multiple magnetic elements + sequence trigger: prevents bypass with simple permanent magnets — meets ISO 14119 high-level coded requirements.
- Dual-channel OSSD: safety output to PLe / SIL3 / Cat.4 for high-risk hydraulic / mechanical machine guarding.
- Misalignment tolerance: 0 – 10 mm horizontal / 0 – 6 mm vertical make distance — forgiving on settled doors and warped frames.
- Cascadable: chain multiple units (E-models) into a single safety loop, reducing PLC input points.
- Flexible coding: universal coding for general use, unique coding (D-models) for high-confidentiality applications.
- Diagnostic output: supports status diagnosis for predictive maintenance and faster troubleshooting.
- Certified: CE marked; designed to ISO 13849-1, IEC 60947-5-3 and ISO 14119.
Typical Applications
- Guard doors on machine tools and CNC enclosures.
- Robotic cells — entry / loading hatches and fence gates.
- Hazardous-area isolation zones — chemical, pharmaceutical, food & beverage rooms.
- Test & calibration cabinets where high-confidentiality / anti-tamper coding is required.
- Combined deployment with DX-D6 electromagnetic door locks for redundant interlock chains.
