Introduction to the AMA5 / 500AS Surface Armature Housing and its key features
The AMA5 / 500AS (also referenced as 500-ASE) surface armature housing is a purpose-built bracket for 500 kg magnetic locks. Designed to provide a neat, durable surface-mount solution for the armature plate, this accessory complements heavy-duty maglocks used on commercial and high-security doors. Key features include a robust aluminium construction, bevelled edges and a metallic finish, compatibility with standard armature plates, and a typical fixing using an M8 tapped hole. With dimensions of 193 mm (H) x 74 mm (W) x 14 mm (D) and a variant-dependent weight of about 0.47 kg, the AMA5 / 500AS is compact yet engineered to support the demands of 500 kg (approx. 1,100 lb) magnetic locking systems.

- Dimensions: 193 mm (H) x 74 mm (W) x 14 mm (D).
- Weight: Approximately 0.47 kg (variant-dependent).
- Compatibility: Compatible with CDVI 500 kg series and most 500 kg surface maglocks that share the same armature geometry.
Each specification of the AMA5 / 500AS translates into a practical advantage in the field. The aluminium construction delivers a balance of strength and low weight: it is strong enough to withstand the forces associated with a 500 kg magnetic lock, while being light enough to simplify handling and installation. The bevelled, metallic finish not only improves aesthetics on visible door edges, it also resists wear and provides a professional look for commercial and institutional settings.
The M8 tapped hole is an industry-standard fixing which means installers can use widely available fasteners and armature plates without needing bespoke hardware. The compact footprint (193 x 74 x 14 mm) makes the housing unobtrusive on most door leaves and helps maintain the visual line of the door while protecting the armature plate. The weight and material choices also help minimize added strain on the door leaf and frame compared to heavier housings.
Use cases and scenarios where the product excels
The AMA5 / 500AS is ideal for commercial entrances that require strong maglocks but where surface mounting is preferred or necessary. It is often used on office access-control doors, retail back-of-house entrances, and facilities where retrofitting a surface maglock is faster and more cost-effective than recessed or frame-integrated solutions.
In data centres, IT rooms and storage areas containing high-value items, reliability and proven load ratings are essential. Paired with a 500 kg maglock, the AMA5 / 500AS ensures the armature plate is securely mounted and protected, providing a dependable mechanical interface for the locking system.
For doors that see frequent use—such as employee entrances, school access points, or healthcare facility internal doors—this housing offers a durable finish that withstands repeated operation and handling. Surface-mounted housings also simplify maintenance and replacement when required.
When upgrading existing doors to magnetic locking, installers often prefer surface-mounted solutions to avoid extensive door modification. The AMA5 / 500AS works well in retrofit scenarios and supports standardisation across door sets where the same armature geometry is used, simplifying spare parts and servicing.
Comparisons with similar products in the market
There are several choices when selecting an armature housing for a 500 kg maglock. The main distinctions are material, finish, mounting approach and compatibility with armature plates. Below are common comparison points and how the AMA5 / 500AS stacks up.
Steel housings are sometimes chosen for their perceived toughness, but aluminium housings like the AMA5 / 500AS offer excellent corrosion resistance, lower weight and easier machining. Aluminium also accepts anodised finishes that maintain appearance over time. For most internal and sheltered external applications, an aluminium housing is sufficient and more installer-friendly.
Recessed housings provide a flush look and are preferred where aesthetics are paramount or where frame space allows. However, recessed installations are more labor-intensive and may require frame modifications. The AMA5 / 500AS excels where fast installation, retrofit capability and protected but visible mounting are priorities.
The AMA5 / 500AS is sold under CDVI references and is sized and finished to mate cleanly with CDVI 500 kg locks. Generic housings may claim compatibility, but small differences in plate geometry or fixing centres can complicate installation. Choosing a housing that is specified for your lock brand reduces callbacks and ensures a snug fit.
The provided cost price in the product record is 22.38 (currency not specified) with a suggested price of 32.50 (assumed GBP in the record). The AMA5 / 500AS sits in an economical price bracket for a quality aluminium housing. Cheaper plastic or thin-sheet alternatives may reduce upfront cost but often sacrifice longevity and finish. Investing in a robust aluminium housing typically reduces lifetime maintenance and replacement costs.
Customer feedback and installer notes
While formal customer testimonials for this SKU may vary by supplier, common installer feedback for well-made surface armature housings of this type tends to highlight a few recurring themes:
- "Solid construction and tidy finish" — installers appreciate the machined look and the housings ability to present a neat, finished appearance on the door leaf.
- "Compatibility with standard plates" — the M8 tapped fixing and CDVI-referenced geometry typically mean fewer on-site adjustments and faster fitment.
- "Good value for money" — compared with inexpensive alternatives that require replacement, aluminium housings are seen as a sensible long-term investment.
- "Easy to service" — surface mounting makes removal and replacement of the armature straightforward during maintenance.
If you require verified customer reviews for procurement decisions, request reference installations or installer feedback from your supplier prior to purchase.
Installation, compliance and warranty considerations
Installation should be carried out by a competent installer following the manufacturer datasheet and instructions. Confirm the exact SKU/variant (AMA5 vs 500-ASE / 500AS) and any applicable conformity markings (CE / UKCA) with your supplier before specifying. The housing is intended to be used with the correct 500 kg maglock and armature plate; improper pairing can compromise performance and safety.
Warranty in this product record is listed as 0. Confirm warranty terms and post-sale support with your supplier—some distributors or manufacturers may offer additional warranty coverage or bundled guarantees when the housing is sold together with the maglock.
Conclusion: why the AMA5 / 500AS is a strong choice
The AMA5 / 500AS (500-ASE) surface armature housing is a practical, economical and durable solution for mounting armature plates on doors fitted with 500 kg magnetic locks. Its aluminium construction, industry-standard M8 fixing, neat dimensions and compatibility with CDVI 500 kg products make it well suited to commercial, data-centre and retrofit applications. Compared to cheaper or less robust alternatives, this housing balances appearance, longevity and ease of installation—reducing maintenance and delivering reliable performance over time.
Before specifying, verify the correct variant, finish and conformity markings with your supplier, and confirm any warranty or support options you require. For installers and specifiers looking for a straightforward, high-quality surface armature housing that pairs with 500 kg maglocks, the AMA5 / 500AS is a compelling choice.
