Brief introductionY37A series Y37A seriestop ↑
Y37A series Y37A series
This series of connectors have the characteristics of bayonet locking mechanism, of quick coupling, of reliable coupling, of environment resistance, of many keys avoiding error mate and of anti-electromagnetic interference, so they are suitable for electric connection in the low frequency AC/DC circuit.
This series of connectors modeled on series снц２３and снц２８connectors of Russia can completely interchange with series снц２３and снц２８ connectors of Russia.
