Kensington Security Slot Orientation and Specifications
The Kensington MicroSaver Security cable has no cable orientation--the cable is attached to a ring, which can spin and thus can be located very near the external features of your product. Slot placement can be either vertical or horizontal.
Lock Clearance Specifications and Electrical Considerations
The Notebook MicroSaver has an interference volume inside the computer equipment it secures. There should not be any electrical components adjacent to the slot, and the MicroSaver product should never be in contact with any electrical components.

Recommended Metal Backing
It is highly recommended that a metal backing be applied to the interior of the housing wall surrounding the Kensington Security Slot. Below is one example of how this backing can be accomplished. It is often possible, however, to utilize a small extension of some existing internal metal structure, such as shielding, to create this reinforcing structure.
Notes:
- Material: >0.8mm 301 Stainless Steel Half Hard, Acrylic Adhesive.
- All indicated dimensions are in millimeters.

K & Lock® Design Specifications and Considerations
The following K & Lock® design should be used to identify products that are compatible with the MicroSaver Security Cable.
 |
This logo is the industry standard for identifying the Kensington Security Slot on computer and electronic hardware. Although this logo is trademarked and owned by Kensington, Kensington freely encourages OEMs to utilize this logo to identify the Kensington Security Slot. Kensington also encourages OEMs to utilize this icon in their product instructions, literature, and marketing materials. Additionally, Kensington encourages OEMs to include the "Kensington Security Slot" in their lists of specs for products, as questions from our end users are becoming more frequent about which products have the Kensington Security Slot.

Artwork. Camera-ready artwork of icon is now available online! Click on one of the links to download.
Symbol. The icon indicates a product is compatible with the Kensington MicroSaver Security Cable. Products so marked can be secured by inserting and locking the Kensington MicroSaver into the Kensington Security Slot.
Orientation. The icon's orientation should be upright on the product when the product is in normal operational orientation. Other icon orientations are not recommended.
Size. The icon size is recommended to vary in height from 5 to 9 mm and must be scaled proportionally from the artwork. A good rule of thumb is to size the K-Logo proportional to other identifying icons on the hardware.
Placement. The K-Lock icon should be placed in a location that visually associates the icon with the Kensington Security Slot.
Use of the Icon in Plastics
Depth. If a recessed icon is used, the non-textured portion of the icon in the drawing below should be recessed from the surface of the product. The depth of the recessed area will vary with the icon size. Refer to the table below:
|
Icon Size (DimY) |
Maximum Icon Depth |
| 5-6 mm |
.3 mm |
| 6-7 mm |
.4 mm |
| 7-9 mm |
.5 mm |
Texture. The raised areas of the icon should have the same texture as the adjoining product surface. The recessed areas should be polished (see drawing above).
Innovative Use of the Kensington Security Slot in Chassis Design
Top computer designers have started incorporating the Kensington Security Slot into the metal framework of their computer hardware for added strength. Additionally, the Kensington Security Slot has been expanded in function to lock closed the chassis' of new desktop computers. This additional feature not only prevents physical theft of the desktop by attaching it to an immovable object, but it also prevents tampering with or theft of the internal components of the desktop computer.
Other ideas for using the Kensington Security Slot include designing it into the hardware to lock notebook computers closed, or to lock CD-ROM drives.
End User Instructions
Part of designing the Kensington Security Slot into your hardware is to ensure that your end users know how to use it with a Kensington Slim MicroSaver. We have included sample instructions below:
