Miniature rectangular low-frequency single (SNP336) and double (SNP337) connectors for DC, AC (up to 3 MHz) and impulse circuits.
Connectors consist of plugs and sockets, with straight case, housings for case mounting or with no case
Connection type: cut-in
Connectors are couplable with low-frequency connectors RPKM1-4
Contact plating: gold, silver
Climate version: all-climate, for inner mounting
Annotation breakdown
SNP337-26 V(R) P1 1(2) 1(7)
SNP336 – connector type: SNP336 – single, SNP337 – double
26 – number of contacts
V(R) – V – plug; S – socket
P – mounting method: soldering, 1 – terminal for wire mounting
1(2) – contact plating: 1 – gold, 2 – silver
1 – case type: 1 – unshielded straight case, 7 – connector body with housings for case mounting, no symbol – no case or housings.
Notes:
SNP 336 with silver plated contacts can have 26, 38, 45, 57, 67 contacts; with gold plated contacts 45, 57, 67 contacts.
SNP337 can have any contact pair layout
Number of contacts for single connector is represented by an even number, for double connector – by a fraction. In case any part of double connector is missing, the representing part of a fraction will be replaced by “S”. Customer can install any other connector instead of missing part, considering that uncoupling force in such case should not exceed 196 N (20 kgf)
