The 090 Reading Head is the recommended antenna where small size
is a requirement.

• Very small and unobtrusive.
• Easy to install.
• Proximity reading range.
• Red and green LED indicators.
• The lowest cost solution.
Installing the 090 Reading Head
Note: the 090 Reading Head must be connected and mounted
before
the self-adhesive label is attached to the front.
1. Choose a suitable position to mount the 090 Reading Head
near the door.
The 090 Reading Head has a range of typically 30cm with an
active Card or Tag, less with a passive Card or Tag, so it must
be mounted in a position where the Card or Tag can easily be
brought within this distance. We recommend it is mounted
approximately one metre above the ground. Also consider ease
of access to the door once the Card or Tag has been read, for
example, it is better to mount the Reading Head near the
opening side of the door rather than the hinge side.
