Project Description

ZRA/ERA.1S Fixed socket, nut fixing

ERA.1S lemo unipole coaxial push pull compatible connector

1. ZRA/ERA.1S Lemo interchangeable unipole coaxial connector brief introduction:

SPRING unipole coaxial connector analogues of Lemo unipole coaxial connector and connector of other companies of the same type making it.  SPRING CONNECTOR can widely apply in Medical, Test & Measurement, ResearchCommunications, Broadcast Connector, Machines, Defense, RoboticAerospace, public sector, Information Systems, MotorsportMiscellaneous applications

2. ZRA/ERA.1S Lemo interchangeable unipole coaxial connector description:

  • Small size, quick insertion and security of the Push-Pull self-latching system
  • There are straight type, elbow (90°) type and other different types of plugs;
  • High frequency: transmission frequency is 3MHZ ∽ 30MHZ;
  • Many functions: in addition to the role of the bridge, it also has the function of processing signals, such as filtering, phase adjustment, mixing, attenuation, detection, limiting, etc.
  • Low standing wave, low loss: meeting the needs of weapon systems and precision measurement;
  • Large capacity, high power: mainly to meet the development needs of the information super high way.
