About the series
What it is
The A1-CONNECT SNTS233 series is an equivalent of the СНЦ233 series (circular low-frequency, bayonet coupling with five-key polarization, EMI protected, internal mounting). Shell sizes 14…39, 3 to 61 contacts Ø1.0, 1.5 and 2.0 mm; cable plugs and panel-mount receptacles, PCB-mount version. Manufacturer's versions: SNTS233.
Stated compatibility
The equivalent's designation is derived from the original: СНЦ233-19/22В1О11 corresponds to ZH233-19/22B1O11, the PCB-mount version СНЦ233-10/18Р2П21 — to ZH233-10/18P2W21, and the key angular positions а, б, в — to a, b, c. The 14…39 shell size range and the 3/14…45/39 contact arrangements match СНЦ233; the key arrangement is the same as in SNTS28, the equivalent of СНЦ28, whose plugs mate with СНЦ233 receptacles. EMI protection is provided by shielding backshells and a conductive shell finish — nickel or cadmium; the anodized version is not suitable for shielded circuits.
Where it is used
The same applications as СНЦ233: inter-unit and cable connections in equipment for industrial automation, instrumentation, transportation, power engineering and telecommunications — within the operating conditions listed in the specifications.
What it replaces and what to check
Replaces СНЦ233 per the equivalent manufacturer's cross-reference table. Before replacement, verify the mounting footprint, contact arrangement, mating part (within the same system), contact plating and temperature range against the drawings of both series; samples are available from 1 piece.
ZH233-19/22B1O11: SNTS233 — series; 19 — number of contacts; 22 — nominal shell size; B — plug with pin contacts (P — receptacle with socket contacts); 1 — cable part (2 — panel part); O1 — crimp contacts (W2 — PCB solder); 1 — gold-plated contacts; then — backshell type per the table and key position a, b, c, d (no letter — normal position).
How to select
Provide the part number of the item being replaced (СНЦ233) or the number of contacts, current, coupling type and operating conditions (temperature, IP rating) — we will select the appropriate SNTS233 version; send your request via BOM quote or cross-reference search.

Questions and answers
How does A1-CONNECT SNTS233 replace СНЦ233?
The equivalent's designation is derived from the original: СНЦ233-19/22В1О11 corresponds to ZH233-19/22B1O11, the PCB-mount version СНЦ233-10/18Р2П21 — to ZH233-10/18P2W21, and the key angular positions а, б, в — to a, b, c. The 14…39 shell size range and the 3/14…45/39 contact arrangements match СНЦ233; the key arrangement is the same as in SNTS28, the equivalent of СНЦ28, whose plugs mate with СНЦ233 receptacles.
What parameters are needed for selection?
The part number of the item being replaced, or the number of contacts, current and voltage per contact, coupling type, temperature range and IP rating, side (plug or receptacle) and termination method.
Can I get samples?
Yes, samples from 1 piece to verify mating and the mounting footprint; volume supply is per your bill of materials.
