About the series
What it is
The A1-CONNECT SNTS127 series is an equivalent of the СНЦ127 series (circular (cylindrical) low-frequency subminiature shielded; bayonet coupling; hermetic panel-mount plug and non-hermetic cable receptacle; wire and PCB termination). Shell sizes 10, 12, 14, 18, 22 and 27; inserts with Ø0.6 and 1.0 mm contacts for 4…102 contacts, mixed and power inserts with Ø1.5…5.5 mm contacts. Manufacturer's versions: SNTS127.
Stated compatibility
The equivalent's manufacturer states that the SNTS127 series is interchangeable and intermateable with СНЦ127 and ОНЦ-БС (ONTS-BS) connectors. The designation repeats the original with letter substitution: СНЦ127-4/10ВП127-1-В — ZH127-4/10B12Z-1-B; numeric versions 5, 6, 7 and 8 are denoted by the letters W, Q, Z and Y, and polarization positions 1–20 are retained. The mounting dimensions of the panel parts — flange square, hole spacing and holes — match the СНЦ127 technical description in all six shell sizes.
Where it is used
The same applications as СНЦ127: 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 СНЦ127 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.
ZH127-4/10B12Z-1-B: SNTS127 — series; 4 — number of contacts; 10 — nominal shell size; B — plug (P — receptacle); 1 and 2 — version and contact plating per the manufacturer's table; Z — panel part with square flange (version 7 of the original designation; 5, 6, 8 — W, Q, Y); 1 — polarization position (1–20); B — all-climate version.
How to select
Provide the part number of the item being replaced (СНЦ127) or the number of contacts, current, coupling type and operating conditions (temperature, IP rating) — we will select the appropriate SNTS127 version; send your request via BOM quote or cross-reference search.

Questions and answers
How does A1-CONNECT SNTS127 replace СНЦ127?
The equivalent's manufacturer states that the SNTS127 series is interchangeable and intermateable with СНЦ127 and ОНЦ-БС (ONTS-BS) connectors. The designation repeats the original with letter substitution: СНЦ127-4/10ВП127-1-В — ZH127-4/10B12Z-1-B; numeric versions 5, 6, 7 and 8 are denoted by the letters W, Q, Z and Y, and polarization positions 1–20 are retained. The mounting dimensions of the panel parts — flange square, hole spacing and holes — match the СНЦ127 technical description in all six shell sizes.
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.
