About the series
What it is
The A1-CONNECT ONTS-BS2 series is an analog of the ОНЦ-БС-2 (ONTs-BS-2) series (circular (cylindrical) low-frequency subminiature quick-disconnect connectors; bayonet coupling; sealed panel-mount plug and unsealed cable receptacle). Shell sizes 10, 12, 14, 18, 22, 27; 4, 7, 10, 19, 32, 50 contacts (contact arrangement diagrams on the manufacturer's page). Manufacturer's versions: ONTS-BS2 (OHS-BC).
Compatibility claims
The manufacturer calls ONTS-BS2 its localized version (国产化型号) of ОНЦ-БС-1(2) per specification бР0.364.030 and builds the part number character by character after the original: OHS-BC-1(2)-4/10-B(P)1(2)-1(2,3)-B ↔ ОНЦ-БС-1(2)-4/10-В(Р)1(2)-1(2,3)-В (1 — silver plating, 2 — gold plating, i.e. OHS-BC-2 corresponds to ОНЦ-БС-2); the table of shell sizes, contact counts, currents and voltages and the mounting dimensions match the original manufacturer's data — interchangeability by footprint and part number is claimed.
Where it is used
The same applications as ОНЦ-БС-2: inter-unit and cable interconnections of equipment in industrial automation, instrumentation, transportation, power engineering and telecommunications — within the operating conditions listed in the specifications.
What it replaces and what to check
Replacement for ОНЦ-БС-2 per the cross-reference table of the analog's manufacturer. Before replacing, verify the 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.
OHS-BC-1(2)-4/10-B(P)1(2)-1(2,3)-B: ONTS-BS2 — series (per the manufacturer's legend: O — circular, H — bayonet, S — subminiature, BC — Б/С); 1 — silver plating, 2 — gold plating; 4/10 — number of contacts / shell size; B — square-flange panel-mount part with pin contacts (В), P — round cable part with socket contacts (Р); 1 — without backshell, 2 — with unshielded straight backshell; 1(2,3) — key position; B — all-climate version. Example: OHS-BC-2-10/14-B1-1-B ↔ ОНЦ-БС-2-10/14-В1-1-В.
How to select
Specify the part number of the item being replaced (ОНЦ-БС-2) or the number of contacts, current, coupling type and operating conditions (temperature, IP rating) — we will select the suitable ONTS-BS2 version; send your request via BOM quote or cross-reference finder.

Questions and answers
How does A1-CONNECT ONTS-BS2 replace ОНЦ-БС-2?
The manufacturer calls ONTS-BS2 its localized version (国产化型号) of ОНЦ-БС-1(2) per specification бР0.364.030 and builds the part number character by character after the original: OHS-BC-1(2)-4/10-B(P)1(2)-1(2,3)-B ↔ ОНЦ-БС-1(2)-4/10-В(Р)1(2)-1(2,3)-В (1 — silver plating, 2 — gold plating, i.e. OHS-BC-2 corresponds to ОНЦ-БС-2); the table of shell sizes, contact counts, currents and voltages and the mounting dimensions match the original manufacturer's data — interchangeability by footprint and part number is claimed.
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 samples be obtained?
Yes, samples from 1 piece to verify mating and footprint; volume supply is per your BOM.
