Low-frequency electrical plug and socket units (rectangular connectors)with hyperboloid contacts.
Designed for DC, AC (with frequencies up to 3 MHz) and impulse circuits. GRPM1U connectors are compatible and interchangeable with GRPM1 (technical requirement version Ke0.364.006 TU) connectors.
Annotation breakdown
Annotation example: connector GRPM2-31(45,61,90,122)Sh(G)O(P,U)1(2)W-VKShU.434416.007 TU
GRPM – series name
1– design index number
31(45,61,90,122)– number of contacts
Sh(G) – connector side (SH – plug, G – socket)
O(P, U) – mounting method, where O – wire mounting, P – straight PCB mounting, U – angular PCB mounting
1(2) contacts plating, where 1 – gold, 2 - silver
W – all-climate version (in accordance with GOST V 20.39.404)
VKShU.434416.007 TU– technical requirement version
