- Input voltage:12 V DC (sensor); EDR supports 12/24 V (verify wiring against datasheet)
- Current draw:Quiescent ≈16 mA; proximity ≈23 mA — low power use suits battery‑backed and low‑current controllers.
- Contacts (sensor):Double‑pole N/O‑N/C rated approximately 30 VAC/DC
- EDR contacts:Triple‑pole EDR for emergency signalling and door control
- Maximum output:1 A @ 30 V DC
- Relay life:~1×10^7 operations — industry‑grade durability for frequent use
- Sensor life:~100,000 hours
- Mounting:Surface or flush; back box included for tidy installation
- Materials / finish:Stainless steel faceplate; high‑impact plastic back box
- Indicators / alarm:Illuminated sensor (red/green); EDR with selectable audible/LED alarm
- Security:Security (Allen) screws supplied to deter tampering
- Hygiene and safety:The infrared touch‑free sensor removes the need for physical contact, reducing pathogen transfer — important in healthcare, food handling and high‑traffic public areas.
- Two functions, one footprint:Combining the no‑touch exit and resettable EDR on a single plate reduces wall clutter, wiring complexity and installation time compared with two separate devices.
- Adjustability:The sensor’s adjustable detection range and the EDR’s selectable audible/LED alarm let installers tailor behaviour to each site’s needs.
- Durability:Stainless steel faceplate and long relay life make this unit suitable for heavy use environments.
- Easy integration:Standard contact ratings, common voltage options (12/24 V for the EDR) and low current draw make the DU‑NT/TF compatible with most access control panels, maglocks and electric strikes.
Installation and safety considerations
The DU‑NT/TF is designed for both surface and flush mounting; a back box is included for surface installations. Installers should verify wiring, input voltage and terminal labelling against the manufacturer’s instruction sheet before powering up. Typical deployments use 12 V DC for the sensor and 12/24 V for the EDR circuits — confirm supply capability and polarity on site. The unit includes security screws and is intended to meet professional installation practices; for emergency exit devices always follow local building and fire codes and the manufacturer’s guidance.
Use cases and scenarios where the DU-NT/TF excels
Because it pairs touch‑free operation with a resettable emergency release, the DU‑NT/TF is especially useful in locations where hygiene, rapid egress in emergencies and tidy integration with access control are priorities. Typical use cases include:
- Hospitals and clinics:Patient wards, operating theatre corridors and isolation areas benefit from touch‑free exits to reduce infection risk. The resettable EDR provides a clear emergency override that can be serviced and reset by authorised staff.
- Education and student accommodation:High pedestrian flow and concerns about cleanliness make a no‑touch solution attractive in schools, colleges and dormitories; the EDR gives controlled emergency release during incidents.
- Offices and commercial buildings:Internal secure doors between zones can use the DU‑NT/TF to provide hygienic egress and a neat single‑plate installation that matches modern finishes.
- Laboratories and cleanrooms:Where contamination control is critical, removing a touchpoint reduces cross‑contamination and supports regulatory best practice.
- Care homes and assisted living:Residents and staff benefit from touch‑free access while the resettable EDR supports controlled emergency response procedures.
How it integrates with access control systems
The DU‑NT/TF provides momentary touch‑free exit inputs plus triple‑pole EDR contacts that can tie into door controllers, alarm panels and lock power supplies. With standard contact ratings and a modest maximum output of 1 A @ 30 V DC, it is well suited to drive input circuits on controllers or to signal alarms and monitoring systems. The illuminated sensor gives clear visual feedback to users, while the EDR’s selectable audible/LED alarm provides local notification during emergency activation.
Comparisons with similar products on the market
When evaluating the DU‑NT/TF against alternatives, there are several points to consider: functionality, construction, installation effort and price.
- Combined: single plate, fewer cutouts, simplified wiring and a cleaner appearance; often lower total cost of parts and installation time.
- Separate: greater flexibility in placement and choice of individual components, but increased wall clutter and higher installation complexity.
- Stainless steel faceplate on the DU‑NT/TF offers superior durability and a professional finish for public buildings; plastic units can scratch or discolour and look lower grade.
- Infra‑red no‑touch sensors are genuinely non‑contact and work regardless of glove use; capacitive sensors still require touch and can be affected by glove or moisture conditions.
At a suggested price of $49.99, the DU‑NT/TF sits attractively for installers and specifiers seeking a robust, dual‑function device without the premium cost of high‑end brand alternatives. Its long relay life and low power draw also reduce maintenance and operating costs over time. Be aware that warranty details should be confirmed with the supplier; verify coverage during purchase.
Customer feedback and installer impressions
Publicly available, attributable customer reviews are not provided here. However, typical feedback from installers and facilities managers who choose combined no‑touch + EDR plates tends to highlight a few consistent themes:
- Ease of installation:Combining two functions on one plate saves on back box positioning and wiring runs.
- Professional finish:Stainless steel faceplates provide a cleaner look and withstand heavy use better than plastic alternatives.
- Reliable operation:Long relay life and adjustable sensor range are noted as practical benefits in busy sites.
- Hygiene advantages:End users, especially in healthcare and food environments, appreciate the reduced touchpoints.
If you require verified customer testimonials, ask your supplier for case studies or contact references who have installed the DU‑NT/TF in similar environments.
Conclusion: Why the DU-NT/TF is a strong choice
The RGL DU‑NT/TF No‑Touch Exit Sensor & Resettable EDR provides a balanced mix of hygiene, safety, durability and value. By combining a reliable infra‑red no‑touch exit sensor with a resettable triple‑pole emergency door release on a single stainless plate, it simplifies installation, reduces wall clutter and meets the practical needs of hospitals, schools, offices and other professional environments. Adjustable detection range, selectable alarm modes, low power consumption and industry‑grade relay life make it a sensible choice where frequent operation and longevity matter. With a modest suggested price point and features tailored to real‑world deployments, the DU‑NT/TF is an effective, compact solution for modern access control needs.
Quick checklist before purchase and installation:
- Confirm input voltage and wiring requirements from the supplied datasheet.
- Verify compatibility with your door controller, maglock or strike (contact ratings: 1 A @ 30 V DC max).
- Check local emergency egress regulations when specifying EDR devices.
- Ask the supplier about warranty and compliance (CE/UKCA) declarations if required.
