## Long description

electro base Dallas iButton key TM1990A-F5-RED is a compact contact-based identification token in red designed for direct-read iButton systems. The TM1990A format places the electronic element inside a durable metal housing that withstands daily handling and contact with stainless readers. The device provides simple, reliable physical identification for access control, time attendance and asset tagging in environments where direct contact readout and a small form factor are required.
Advantages
The metal-encased TM1990A contact key offers mechanical durability and consistent electrical contact for reliable reads with iButton-compatible readers. Its small, pocketable size and red color help with quick visual identification and organization. Because it is a contact token, it does not require batteries or wireless pairing, reducing maintenance and potential communication issues.

Access control systems requiring contact readout
Employee time and attendance tracking
Asset tagging and inventory control in harsh environments
Secure identification where compact physical tokens are preferred
Key specifications
Form factor: cylindrical metal housing with contact interface for iButton readers
Color: red
Read method: direct electrical contact with compatible readers
Durability: metal casing designed for repeated contact and handling
Power: passive (no battery required)
Typical applications: access control, time attendance, asset identification
How to use
Present the TM1990A contact key to the contact area of an iButton-compatible reader so that the metal housing makes firm contact with the reader's probe or contact surface. The reader will detect the token and read its identification data automatically. No pairing or power source is required for the key itself. Handle the key by its housing to maintain reliable contact surfaces and avoid contaminating the contact area with oils or debris.
Usage recommendations
For reliable operation, keep the contact surface clean and periodically inspect the metal housing for heavy wear or corrosion. Use the red color to organize tokens by user group, access level, or function. Ensure readers are compatible with the TM1990A contact format and positioned to allow repeatable, secure contact during normal use.
