About the series
What it is
The A1-CONNECT RBM4 series is an analog of the РБМ4 (RBM4) series (circular (cylindrical) low-frequency compact quick-mating connectors; bayonet coupling; panel-mount plugs sealed (РБМ4) or unsealed (РБМ4Н), receptacles unsealed; panel-mount and cable parts). 4, 7, 10, 19, 24, 32, 50, 55 contacts; contact combinations 1, 2, 7, 9; the range of shell sizes is not given on the page (for РБМ4 — 18…45). Manufacturer's versions: RBM4.
Compatibility claims
The manufacturer calls RBM4 its localized version (国产化型号) of РБМ4, made “in accordance with specification ГЕ0.364.196”, lists the same contact combinations with the same currents and voltages and builds the part number after the РБМ4 scheme with letter substitution (Ш → J, Г → K; РБМ4-4-2Ш1(2,3)-В ↔ PM4-4-2J1(2,3)B), i.e. it claims interchangeability by footprint, contact combinations and part number.
Where it is used
The same applications as РБМ4: 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 РБМ4 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.
PM4-4-2J1(2,3)B ↔ РБМ4-4-2Ш1(2,3)-В; PM4-4-2K6(7)B ↔ РБМ4-4-2Г6(7)-В: RBM4 — series; 4 — number of contacts (4, 7, 10, 19, 24, 32, 50, 55); 2 — contact combination number (1, 2, 7, 9); J — pin contacts (Ш), K — socket contacts (Г); 1 — receptacle without backshell, 2 — receptacle with straight clamp backshell, 3 — receptacle with sleeve backshell, 6 — plug with sleeve backshell, 7 — plug with straight clamp backshell; B — all-climate version.
How to select
Specify the part number of the item being replaced (РБМ4) or the number of contacts, current, coupling type and operating conditions (temperature, IP rating) — we will select the suitable RBM4 version; send your request via BOM quote or cross-reference finder.

Questions and answers
How does A1-CONNECT RBM4 replace РБМ4?
The manufacturer calls RBM4 its localized version (国产化型号) of РБМ4, made “in accordance with specification ГЕ0.364.196”, lists the same contact combinations with the same currents and voltages and builds the part number after the РБМ4 scheme with letter substitution (Ш → J, Г → K; РБМ4-4-2Ш1(2,3)-В ↔ PM4-4-2J1(2,3)B), i.e. it claims interchangeability by footprint, contact combinations and part number.
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.
