We recently acquired the inventory of a large marine parts distributor that went out of business. These are new old stock items in great cosmetic condition, however the factory original packaging was not salvageable.
We were able to determine these are Xantech 283D Blink-IR Designer Emitters based on the model description located on the factory original label.
Details:
Visible, red blink, low output version of the 282D
Clear adhesive film for attachment to IR window of controlled component
Includes three pre-cut adhesive backings for replacement purposes
