XNX-UTAV-NNIV1 – Universal Gas Detector with IR Methane Sensor
Honeywell XNX Series delivers a versatile, explosion-proof gas detector. It supports mV, catalytic bead, electrochemical, and IR sensors. The XNX-UTAV-NNIV1 model includes an integrated IR hydrocarbon sensor for methane (0-100% LEL / 0-5% v/v). This universal transmitter works with 3 or 4-wire systems and offers 4-20mA with HART as standard. It is built for rugged indoor and outdoor environments.
- Multi-purpose detector (MPD) – field serviceable mV, catalytic bead, and IR cell capability
- Simple plug-in sensors and replaceable electrochemical cells reduce downtime
- Multiple communication options – 3 relays, MODBUS, and FOUNDATION Fieldbus (pending)
- Optional local IS port for handheld HART configurator
- NEMA 4X / IP66 – suitable for harsh indoor and outdoor applications
- Approvals – UL and CSA certified for safety

Frequently Asked Questions (FAQ)
Q: Can I use this detector for gases other than methane?
A: Yes, the XNX platform supports various mV, catalytic, and electrochemical sensors. Order the specific sensor for your target gas.
Q: Is the 4-20mA output isolated?
A: Yes, you can configure it for source, sink, or isolated operation via the wiring options.
Q: What is the expected sensor life?
A: IR sensors typically last 5+ years. Catalytic beads and electrochemical cells have 2-3 years depending on exposure.
Q: Does it work in high humidity or rain?
A: Yes, IP66/NEMA 4X rating ensures protection against water jets and dust.
Q: How do I connect a handheld configurator?
A: Use the optional local IS port (HART) for direct connection without opening the enclosure.
Q: Can I retrofit this with a different sensor type?
A: Absolutely. The MPD design allows field swapping of mV, catalytic, or IR sensors.
Q: What is the maximum cable distance?
A: For 4-20mA, up to 3000 ft (depending on wire gauge). Use shielded cable for best performance.
Q: Do I need a separate power supply?
A: The detector operates on 24V DC (typical). It draws minimal current, suitable for most loop-powered systems.
Selection Guide – How to Choose
- Identify your gas – choose the correct sensor type (IR for methane, electrochemical for toxic gases)
- Check the environment – outdoor? Use NEMA 4X. Indoor? Standard housing works.
- Communication needs – HART is standard; add relays or MODBUS if required.
- Mounting type – ¾” NPT conduit or cable glands, both supported.
- Wiring configuration – 3-wire for source/sink, 4-wire for isolated output.
