Honeywell XNX XNX-AMAV-FNNNN – no sensor (transmitter body), mV, ATEX, Aluminium, M25
XNX-AMAV-FNNNN is a Honeywell XNX universal transmitter body with the mV personality, ATEX / IECEx (INMETRO on selected MPD SKUs), 4 × M25 entries, LM25 aluminium (painted), Foundation Fieldbus + 4–20 mA HART, no local HART port, and no MPD sensor in the carton. Order it when the field later fits an MPD catalytic or MPD IR head (CB1 / IV1 / IF1 / IC1) instead of a factory-configured detector.

Why this personality / sensor
The mV personality is the millivolt interface for Honeywell MPD heads. Catalytic and MPD IR share that board; an IR Optima/Excel head will not talk to this SKU, and an electrochemical cell needs the EC personality. Buy a body when the sensor slate is still open or when you stock transmitters separately from MPD cartridges.
Personality and replaceable parts
XNX-AMAV-FNNNN uses the mV personality (MPD catalytic / MPD IR) board and mates with Honeywell MPD catalytic bead or MPD infrared sensors. This SKU ships without a sensor; order the head by gas. Spares live on product-3991. Do not substitute Sensepoint XCD cartridges on XNX.
Typical applications
Typical body SKUs sit in a warehouse next to mixed MPD stock: pump rooms that may take catalytic LEL, biogas roofs that need methane IR, LPG pits that need propane IR, and inerting cabinets that need CO₂. The transmitter is already certified and threaded; you only mate the MPD later.

Installation and wiring
Wall-mount XNX-AMAV-FNNNN (LM25 aluminium (painted), approx. 2.8 kg) on a rigid stand sized for that mass. This SKU uses 4 × M25 entries—glands must match; do not retap XNX-AMAV-FNNNN. Land XNX-AMAV-FNNNN 4–20 mA HART per the loop drawing; relays/Modbus/FFB exist only on the matching option board. Magnetic-wand menus on the XNX-AMAV-FNNNN lid stay non-intrusive. XNX-AMAV-FNNNN is a body: wall-mount the transmitter first and mate the head after the personality is confirmed—do not buy a configured SKU until the gas is frozen.
FAQ

- Manual links on SKU/hub pages.
- Install?
- Torque, entries and earthing per the manual.
- Calibration?
- Per fitted sensor and target gas.
- Local HART?
- Depends on the local-HART digit — do not confuse with other options.
- Which sensors?
- CAT/IR/EC etc. via personality/sensor configuration digits.
