The A-22D-A09 is the Belimo mounting plate for the S housing used by the 01UT and 22UT outdoor temperature sensor families. The grey polycarbonate plate (RAL 7001) screws to the mounting surface Ñ typically an exterior wall, mast, or rooftop equipment rack Ñ and the sensor housing snaps onto the plate via two integrated clips on the housing body. This separates the wiring stage from the sensor installation: install the plate and run the conduit/wiring first, then clip the sensor on at commissioning.
The mounting plate ships included with every 01UT and 22UT sensor. Order this SKU as a spare or replacement when: (1) the original plate is damaged during installation or service (cracked, stripped screw boss), (2) you're retrofitting a sensor to a new location and want to leave the old plate in place at the previous location, (3) you're pre-staging plates ahead of a large installation so wiring can be completed before sensors arrive on site, or (4) you've lost the original plate during shipping or unpacking. Compatible with all 01UT-5.. and 22UT-5.. variants Ñ the S housing is the same chassis across both lines.
Key Features
The mounting plate is installed first; the sensor housing then clips onto the plate via two integrated tabs on the housing body. To service the sensor, press the release tab and lift the housing off Ñ the plate stays mounted and the conduit/wiring stay routed. Clean and reusable for the lifetime of the installation.
Grey (RAL 7001) UV-resistant polycarbonate Ñ designed for direct outdoor exposure alongside the sensor housing. Withstands sun, rain, snow, and temperature cycling without degrading the screw bosses or warping the mounting surface.
Mounts to wood, concrete, or sheet-metal surfaces with two installer-supplied screws (or anchors for concrete). Mounting holes on 28 mm (1.10") vertical spacing; clearance hole at the top for cable/conduit entry.

Frequently Asked Questions
Does my new 01UT or 22UT come with a mounting plate, or do I need to order this separately?
The mounting plate is included with every new 01UT and 22UT sensor Ñ you don't need to order one separately for a standard new installation. Order the A-22D-A09 as a spare or replacement: when the original is damaged, when relocating a sensor and leaving the old plate at the previous site, when pre-staging plates ahead of a large installation, or when the original was lost.
Which sensors fit on this mounting plate?
All Belimo outdoor temperature sensors using the S housing chassis. This covers the entire 01UT-5.. family (passive Ñ Pt100, Pt1000, Ni1000, NTC10k Type II, NTC10k3 Precon, NTC20k) and the entire 22UT-5.. family (active Ñ 0-10V and 4-20 mA variants). The 01UT and 22UT install instructions PDF (belimo_01UT_22UT_installation-instructions.pdf) covers mounting plate use for both.
How does the sensor attach to the plate?
The sensor housing has two integrated snap-on tabs that clip onto matching features on the plate. Press the release tab at the top of the housing to lift the sensor off for service Ñ the plate stays mounted, the conduit and wiring stay routed in place. No tools needed for the snap-on connection itself.
Does the plate include screws for wall mounting?
No Ñ installer supplies the screws (or wall anchors for concrete/masonry surfaces). The mounting holes are 4 mm (0.16") diameter on 28 mm (1.10") vertical center-to-center spacing. Use #6 or #8 screws sized to the mounting surface.
