## DS9093F-R Electronic Component Overview The **DS9093F-R** is a specialized mechanical mounting accessory designed by Analog Devices (formerly Maxim Integrated). It is specifically engineered to hold and protect **iButton** devices, which are small, rugged data carriers. --- ### Technical Specifications and Features | Category | Specification | | :--- | :--- | | **Component Type** | iButton Mounting Fob (Key Ring) | | **Material** | Plastic (Polycarbonate) | | **Compatibility** | F5 MicroCan iButtons | | **Attachment Method** | Snap-in / Press-fit | | **Color** | Black (typically, though codes vary) | | **Durability** | High impact resistance | --- ### Functional Design The DS9093F-R serves several critical roles in an electronic identification system: 1. **Mechanical Retention**: It provides a secure "cradle" for the F5-size iButton. Once the iButton is pressed into the fob, it is held firmly in place by plastic tabs. 2. **User Interface**: It transforms a small metallic disk into a portable key-like form factor that can be easily attached to a keychain or lanyard. 3. **Protection**: The raised edges of the plastic fob protect the stainless steel casing of the iButton from excessive lateral impacts and scratches. 4. **Access Alignment**: It is designed to ensure that when a user touches the iButton to a probe (Reader), the electrical contacts are properly aligned. ### Typical Applications The DS9093F-R is used in environments where portable data or identity is required: * **Access Control**: Personnel identification for building entry. * **Time and Attendance**: "Clocking in" at workstations. * **Asset Tracking**: Identifying specific tools or mobile equipment. * **E-Cash**: Low-value transactions in cafeterias or transit systems. --- ### Assembly Instructions To use the DS9093F-R: 1. Align the **F5 iButton** (the thicker 16mm disk) over the circular opening of the fob. 2. Apply firm pressure until the iButton "snaps" past the retention clips. 3. The flange of the iButton should be flush with the plastic casing to ensure a clean electrical connection with the reader probe.
