MIDAS-E-LEB | Honeywell Midas® butane LEL 0–100 %LEL
MIDAS-E-LEB is a Honeywell Midas® 2-year E cartridge for butane LEL (n-C₄H₁₀), range 0–100 %LEL, catalytic / pellistor. It plugs into the MIDAS-T-004 extractive transmitter — not a Sensepoint XCD diffusion head. Sample line up to 30 m FEP at ~500 mL/min.

Transmitter 150×65×153 mm / 0.8 kg; NF₃ pyrolyzer 70×63×85 mm / 0.41 kg; high-temp PFC pyrolyzer 100×101×140 mm / 1.36 kg.
Why this SKU
Midas is extractive: the cell sits in the tool cabinet while FEP pulls sample from the valve box. butane LEL uses catalytic / pellistor. Pyrolyzed species need MIDAS-T-00P / T-HTP / T-NP1 or the cartridge will not read.
Mates and spares
MIDAS-E-LEB mates to MIDAS-T-004. Pump MIDAS-A-007, internal filter MIDAS-A-009. Same-gas 1-year S cartridge is the short-warranty sibling. Calibration notes live on product-2679.
Typical applications
Gas cabinets, VMBs, wet benches and CVD/etch exhaust. MIDAS-E-LEB locks gas and cartridge life; budget transmitter, pump A-007 and internal filter A-009 on the PM cycle.

Install and sample line
Wall-mount MIDAS-T-004 on the pre-drilled chassis or DIN kit A-036, then insert MIDAS-E-LEB. Sample 1/8″ID×1/4″OD FEP to 30 m; exhaust 1/4″ID×3/8″OD to 30 m. End-of-line filter 0780248 or 1830-0055/0027 by gas. 24 VDC (−15%/+10%) or PoE 48 V; pyrolyzer load up to 12.95 W. 0–40 °C, 0–30 °C with pyrolyzer.
FAQ
- Can MIDAS-E-LEB plug into Sensepoint XCD?
- No. Midas is an extractive cartridge; XCD is a diffusion sensor housing. They do not mate.
- Does MIDAS-E-LEB need a pyrolyzer?
- Gases marked ** (CH₂F₂, C₄F₆, C₅F₈, NF₃, CH₃F) need MIDAS-T-00P / T-HTP / T-NP1 plus a ventilated cover.
- MIDAS-E-LEB vs the S cartridge?
- Same gas and range. E is 2-year extended warranty; S is 1-year. LEL cartridges warrant 2 years but can be calibrated to 5.
- How is 4–20 mA landed on MIDAS-E-LEB?
- 3-wire sink, 3-wire source or 4-wire isolated 0–21 mA; plus 3 relays and Modbus TCP / PoE. Max 14 AWG.

Quote and lead time
Stock and lead time are batch-based. If an E cartridge is short, look at the same-gas S cartridge. Pyrolyzed gases need the pyrolyzer ordered with the transmitter.
