Bosch SURFACE MOUNT BOX WALL OR CEILING - NDA-U-PSMB

Bosch NDA-U-PSMB Surface Mount Box — Wall or Ceiling

Overview

The Bosch NDA-U-PSMB is a purpose-built surface mount box designed for wall or ceiling deployment of compatible Bosch dome cameras. At Φ138 mm (5.4 in) diameter and 50 mm (2.0 in) height, it keeps the camera profile tight against the structure — no pendant arm, no exposed conduit box. The aluminum alloy shell and IK10 impact rating make it a credible choice for environments where a plastic housing would be a liability. This is the enclosure you reach for when a flush, clean installation matters and the location sees foot traffic, carts, or other physical contact risks.

Key Features

• IK10 Impact Protection: IK10 is the highest rating on the IEC impact protection scale — 20 joules of impact energy, equivalent to a 5 kg mass dropped from 400 mm. In corridor, stairwell, or warehouse deployments where accidental (or deliberate) contact with the camera assembly is a real scenario, IK10 means the housing survives where a standard plastic enclosure would crack or shatter.
• Aluminum Alloy Construction: The die-cast aluminum shell handles mechanical stress and resists deformation better than ABS or polycarbonate housings. It also dissipates heat more effectively — a factor in ceiling-mount installs where the enclosure sits close to the ceiling surface and ambient temperatures can climb in summer months.
• Compact Form Factor — Φ138 × 50 mm: The 138 mm footprint keeps the mount visually proportionate to small dome cameras. The 50 mm (2.0 in) depth gives enough internal volume for cable management and connections without pushing the camera noticeably off the ceiling or wall surface.
• 428 g Installed Weight: At under one pound (0.94 lb), the NDA-U-PSMB adds minimal load to the camera assembly. In drywall or drop-ceiling installs, that matters — lighter total weight reduces anchor requirements and simplifies conduit-entry alignment during rough-in.
• RAL 9003 White Standard Finish: The standard white (RAL 9003) finish integrates cleanly in commercial interiors — offices, retail, hospitality — without drawing attention. RAL 9003 is a defined color standard, so touch-up paint matching is straightforward if the surface is scuffed during installation.
• Salt Mist Tested (IEC 60068-2-52): IEC 60068-2-52 salt mist testing validates corrosion resistance in coastal or high-humidity environments. Even for indoor installs near loading docks, commercial kitchens, or natatoriums, a housing that has passed this test is measurably more durable than one that hasn't.
• Vibration Resistance — NEMA TS2: NEMA TS2 vibration testing is the standard used for traffic signal equipment — a deliberately punishing benchmark. For camera mounts near HVAC equipment, compressors, manufacturing floors, or rooftop installations with wind load, this rating means the housing won't work fasteners loose or develop stress cracks over time.
• Shock Resistance — IEC 60068-2-27: Tested to IEC 60068-2-27 shock standards, the NDA-U-PSMB can handle the impulse loads common in industrial and warehouse environments — forklift vibration, door impacts, and similar transient mechanical events that accelerate wear on untested enclosures.

Integration and Compatibility

The NDA-U-PSMB is engineered for the Bosch Security Systems camera line. Verify camera model compatibility against Bosch's current accessory compatibility matrix before ordering — dome camera families vary in base diameter and mounting pattern. This enclosure is for surface mounting only; it is not a pendant, parapet, or in-ceiling recessed housing. For PoE switch pairing and network infrastructure planning for your Bosch camera deployment, see the PoE switches category. For broader camera selection guidance within the Bosch lineup, the IP cameras section covers the full range of compatible dome and fixed cameras.

Frequently Asked Questions

Q: What is the diameter and height of the NDA-U-PSMB?

A: The NDA-U-PSMB measures Φ138 mm (5.4 in) in diameter and 50 mm (2.0 in) in height.

Q: What impact rating does the NDA-U-PSMB carry?

A: The NDA-U-PSMB is rated IK10 — the highest level on the IEC impact protection scale, equivalent to withstanding a 20-joule impact.

Q: What material is the NDA-U-PSMB housing made from?

A: The housing is constructed from aluminum alloy, providing mechanical strength, heat dissipation, and corrosion resistance.

Q: Is the NDA-U-PSMB suitable for coastal or high-humidity environments?

A: It has been tested to IEC 60068-2-52 salt mist standards, which validates its corrosion resistance in coastal, high-humidity, or chemically active environments.

Q: Can the NDA-U-PSMB be mounted on both walls and ceilings?

A: Yes. The NDA-U-PSMB is designed for surface mounting on either walls or ceilings.

Q: What is the standard color of the NDA-U-PSMB?

A: Standard color is White, RAL 9003.

The NDA-U-PSMB is one of those components that installers tend to underspecify until they're standing in front of a scuffed or cracked housing six months post-install. The IK10 rating on this aluminum enclosure is what sets it apart from typical dome camera back-boxes — 20 joules is serious resistance, and aluminum alloy construction means you're not relying on a polymer to absorb repeated contact in a busy corridor or stairwell.

Technical Highlights:

• IK10 Impact Rating: 20-joule impact resistance — suitable for any location where physical contact with the housing is a realistic risk. Stairwells, loading areas, retail stockrooms.
• NEMA TS2 Vibration + IEC 60068-2-27 Shock: Both standards indicate the mount will hold alignment and fastener torque under sustained mechanical stress — HVAC proximity, industrial floors, rooftop wind load.
• IEC 60068-2-52 Salt Mist: Corrosion resistance is verified, not assumed. For covered parking structures, natatoriums, or coastal facilities, this matters even for interior-adjacent mounts.

Deployment Considerations:

• The Φ138 mm footprint is sized for compact dome cameras. Verify the base diameter of your specific Bosch camera model against the NDA-U-PSMB mounting pattern before procurement — not all dome families share the same footprint.
• This is a surface mount only — it does not function as a pendant arm, recessed ceiling mount, or parapet bracket. If your installation requires camera offset from the surface, a different accessory is needed.

For high-traffic commercial interiors — retail stores, school corridors, hospital common areas — where the camera enclosure will see incidental contact and the install needs to look intentional rather than industrial, the NDA-U-PSMB delivers the right combination of impact durability and clean white finish without requiring a heavier or more complex mounting solution.
