Why this part number
Keep OPTIMAREDUCERM25M20 on its own BOM line so windows, lamps, PCBs, glands and brackets can be replaced on their own cycle. Do not bury it under 2108N4000N, and do not fit XCD or XNX spares on Optima optics.
Spares and mates
OPTIMAREDUCERM25M20 is Searchpoint Optima Plus Adaptor. This SKU is a spare or accessory and needs an Optima Plus detector. Matrix: product-2698. Do not substitute Sensepoint XCD cartridges or XNX personalities.
Typical applications
Use OPTIMAREDUCERM25M20 against installed Optima Plus points: dust barriers after deluge, flow housings on extractive loops, cups and cylinders at annual gas. Match the detector thread (M20 vs NPT) before the box ships.

Installation and service
Isolate power before swapping OPTIMAREDUCERM25M20. Refit seals to the specified torque and keep M20/M25/NPT families apart. Zero and span afterwards; keep fingerprints and condensation off the optics.
FAQ
- Will OPTIMAREDUCERM25M20 detect gas by itself?
- No. OPTIMAREDUCERM25M20 is a Adaptor (Optima Plus Cable Gland Reducer M25 to M20) and needs an Optima Plus detector body.
- Can I fit an XCD/XNX spare instead of OPTIMAREDUCERM25M20?
- No. Optima optics, seals and connectors are unique.
- Which detector does OPTIMAREDUCERM25M20 mate with?
- New builds: current 2108N SKUs such as 2108N4000N. Installed base: read the 2108B/2108N nameplate first.
- Thread mix-ups?
- Yes. Glands, plugs and adaptors split M20 / M25 / 3/4" NPT. Copy the detector nameplate.
- Calibrate after fitting?
- Zero and span after window, lamp or detector swaps. Brackets and tags do not need gas.
- Lead time?
- Lot-based. Do not substitute a look-alike OPTIMA* SKU without matching the part number.
