DAS ARS-NC Heavy Duty Reed Switch NC with 380mm Armoured Cable & 40mm Gap

Product SKU: ARS-NC

Product Overview

The DAS ARS-NC Heavy Duty Reed Switch NC with 380mm Armoured Cable & 40mm Gap is a rugged surface mounted magnetic reed switch designed for compatible alarm, access control and security monitoring applications. It is ideal for metal doors, windows, fences and gates where a durable sealed contact is required, especially in commercial and industrial environments. The ARS-NC features a high strength extruded alloy-zinc housing, grey finish, normally closed reed switch operation and a wide gap of at least 40mm, making it suitable for heavier openings and wider alignment tolerances. Each unit is completely encapsulated in epoxy glue, helping protect the reed switch assembly in demanding installations where a more robust surface mounted contact is preferred over a standard plastic reed switch.

Key Capabilities

Best For

• Commercial Doors: Suitable for compatible alarm systems monitoring heavier commercial doors and frames.
• Metal Door and Window Monitoring: Ideal where a rugged magnetic reed switch is required for metal openings.
• Fences and Gates: A practical option for gates, fence openings and perimeter points needing durable contact monitoring.
• Industrial Environments: Designed for installations where a rugged sealed contact is preferred over a standard plastic reed switch.
• Wide-Gap Applications: Useful where a minimum 40mm gap is needed due to alignment, movement or mounting surface conditions.

Why Choose the ARS-NC

Choose the DAS ARS-NC when the installation needs a heavy duty surface mounted reed switch for commercial or industrial monitoring points. Its alloy zinc housing, epoxy encapsulated construction and 380mm armoured cable make it better suited to rugged applications than standard plastic surface contacts. The normally closed contact format and wide ≥40mm gap provide a practical solution for compatible alarm and access control systems monitoring metal doors, gates, fences and wider openings. This model, supplied by Security Wholesalers, is a practical choice for installers needing a robust armoured reed switch for reliable low-voltage open/close monitoring.

Key Features & Technical Specifications

Ideal Use Cases

Choosing the Right Model

• Choose this model if: You need a heavy duty NC surface mounted reed switch with alloy zinc housing, 380mm armoured cable and ≥40mm gap.
• Choose a plastic reed switch if: The installation is indoors, low-risk and does not require a rugged metal housing or armoured cable.
• Choose a recessed reed switch if: The project requires hidden installation inside the door and frame rather than surface mounting.
• Choose a different contact type if: The system requires normally open or changeover contact operation instead of normally closed monitoring.
• Check before installation: Confirm contact type, gap, cable route, metal surface mounting, circuit compatibility and magnet alignment.

FAQs

1. What is the DAS ARS-NC used for?
   The DAS ARS-NC is used as a heavy duty surface mounted magnetic reed switch for compatible alarm and access control systems. It monitors the open or closed state of metal doors, windows, fences, gates and other protected openings.
2. Is the ARS-NC suitable for metal doors?
   Yes. The ARS-NC is described as ideal for metal doors and windows, as well as commercial applications where a wide gap is needed. Correct magnet alignment and final testing are still important because metal surfaces and movement can affect performance.
3. What makes this reed switch heavy duty?
   The ARS-NC uses a high strength extruded alloy-zinc housing and is completely encapsulated in epoxy glue. It also includes a 380mm armoured cable, making it a more rugged option for commercial and industrial environments than a standard plastic contact.
4. Is this reed switch normally closed?
   Yes. The ARS-NC is a normally closed reed switch. The installer should confirm the connected alarm panel or access control controller is configured for NC contact monitoring before installation.
5. What gap does the ARS-NC support?
   The ARS-NC has a listed gap of at least 40mm. This wide gap is useful for gates, metal frames and commercial openings where the magnet and reed switch may not sit as close together as a standard contact requires.
6. Can it be used on gates or fences?
   Yes. The ARS-NC is suitable for compatible monitoring applications on fences and gates where a rugged sealed unit is required. The installer should ensure the contact is protected from mechanical impact and that the cable route is secured.
7. Does it include armoured cable?
   Yes. The ARS-NC includes a 380mm armoured cable. This helps protect the exposed cable section near the switch body, especially in installations where the wiring may be more vulnerable to damage or interference.
8. What should I check before buying the ARS-NC?
   Before buying the ARS-NC, confirm that your system requires a normally closed surface mounted reed switch, the ≥40mm gap suits the opening, and the rugged alloy-zinc housing is appropriate for the environment. This model is available through Security Wholesalers for compatible commercial and industrial monitoring applications.
