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 is catalogue-rated for circuits up to PL e 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 14119 Type 4 interlocking device rated for ISO 13849-1 PL e circuits.

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 transistor safety output: 150 mA safety output plus 50 mA auxiliary output, catalogue-rated for ISO 13849-1 PL e circuits.
- 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 with reference to ISO 13849-1 and ISO 14119 (certification documents on request).
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.
Frequently Asked Questions
Is the DX-R1 an ISO 14119 high-level coded interlock?
Yes. The DX-R1 uses multiple magnetic-sensitive elements that must be triggered in a unique sequence, so the unique-coding D-models qualify as high-level coded actuators under ISO 14119, the strongest tamper-resistance class. Universal-coded versions are low-level coded. Both are Type 4 non-contact interlocks suitable for guard-door and RFID coded safety switch style applications.
What safety level and performance level does the DX-R1 reach?
Through its dual-channel safety output, the DX-R1 is rated by the factory catalogue as an ISO 14119 Type 4 interlocking device suitable for circuits up to ISO 13849-1 PL e. No SIL or Category figure is published for the switch on its own. Pair it with a safety relay or safety PLC that provides EDM feedback and dual-channel evaluation — the performance level actually achieved belongs to the complete safety function, not to the switch alone.
Should I order NPN or PNP, and do I need a cascade model?
PNP (sourcing) suits most modern PLC safety inputs; NPN (sinking) fits some Asian control schemes. Choose an E-model (6-core) when you want to cascade several switches into one safety loop and reduce PLC input points; choose an F-model (4-core) for a single guard door. Match the output and coding type to the unit being replaced.
How much door misalignment does the DX-R1 tolerate?
It has a horizontal make distance of 0–10 mm and a vertical make distance of 0–6 mm, with break distances above 25 mm and 15 mm respectively. This wide hysteresis tolerates settled doors, warped frames and vibration, while still guaranteeing a guard-door open signal once the actuator moves clearly out of range.
What ingress protection does the DX-R1 offer for washdown areas?
The standard rating is IP65, with IP67 and IP68 available as custom orders, in a flame-retardant thermoplastic housing. This makes it suitable for humid, dusty and washdown environments such as food and beverage, pharmaceutical and chemical isolation rooms. Operating range is −10 °C to +55 °C with 24 V DC supply and a 60 ms response time.
