Analog Devices Inc./Maxim Integrated DS9093AR+

Overview

DS9093AR+ from Maxim Integrated is a lead-free, RoHS-compliant angled iButton® fob designed for thumbpad-style mounting of F5 MicroCan® iButtons in access control and identification systems. It supports momentary-contact applications, features red color coding, requires no additional hardware for permanent mounting, and is rated for mechanical durability under key-ring handling.

For engineers reviewing the DS9093AR+ datasheet, DS9093AR+ pinout, DS9093AR+ application, or DS9093AR+ equivalent, this product serves as a mechanical mounting solution-not an electronic component-with defined physical interface compatibility, color-coded identification, and F5 MicroCan-specific cavity geometry.

Technical Context

The DS9093AR+ is a passive mechanical housing engineered exclusively for the F5 MicroCan iButton form factor (16mm diameter, 3.2mm thickness). Its angled cavity enables ergonomic thumbpad orientation while maintaining full electrical contact via the stainless-steel lid and internal spring contact.

It provides no active circuitry, voltage regulation, or signal conditioning. All electrical functionality derives solely from the inserted iButton device (e.g., DS1990A, DS1991), with the DS9093AR+ contributing only mechanical retention, environmental protection, and user-identifiable color coding (red).

Key Specifications

Availability

DS9093AR+ is available at Aetrix Electronics and suitable for access control systems, time-and-attendance terminals, and secure asset tagging requiring stable component supply and consistent mechanical interface specifications.

Supply support for DS9093AR+ includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and digital ICs for industrial, communications, and computing applications.

The DS9093AR+ belongs to the iButton key ring mount product line, developed specifically to provide standardized, color-coded, mechanically robust housings for F5 MicroCan iButton devices in human-interface identification systems.

FAQ

Does the DS9093AR+ contain any electronic circuitry or silicon?

No, the DS9093AR+ is a purely passive mechanical housing. It contains no ICs, transistors, or conductive traces beyond the internal spring contact that interfaces with the iButton's lid. All electronic functionality-including memory, authentication, or temperature sensing-resides entirely within the iButton device inserted into the DS9093AR+, such as the DS1990A or DS2401.

Is the DS9093AR+ compatible with iButton models other than F5 MicroCan?

No, the DS9093AR+ is dimensionally and mechanically specified only for F5 MicroCan iButtons (16mm diameter, 3.2mm thickness, stainless-steel lid). It does not accept older F1 or F2 formats, nor non-Maxim iButton variants. Compatibility is confirmed by Maxim's official mechanical drawings and insertion force testing for F5 form factor only.

What is the purpose of the red color on the DS9093AR+?

The red color on the DS9093AR+ serves as a factory-assigned visual identifier for quick recognition in multi-fob deployments-such as assigning red fobs to facility managers and blue fobs to contractors. It has no electrical or functional significance but supports operational consistency and error reduction in high-volume access control rollouts.

Can the DS9093AR+ be used with the DS9093RA Lock Ring?

No, the DS9093RA Lock Ring is intended only for the DS9093N and DS9093F fobs. The DS9093AR+ uses a flange press-fit design that achieves permanent retention without auxiliary hardware. Adding the DS9093RA Lock Ring is incompatible due to differing cavity geometry and retention mechanism.

Does the DS9093AR+ require soldering, wiring, or PCB integration?

No, the DS9093AR+ is a standalone mechanical accessory with no electrical terminals, pads, or connectors. It mounts directly onto a key ring or lanyard and interfaces solely with the iButton it houses. No PCB layout, soldering, or electrical integration is involved-its role is purely physical containment and orientation.
