SECURE HIGH-DENSITY PUSH-PULL CONNECTOR

PEI-Genesis offers LEMO’s B-Series push-pull connector: a secure, push-pull latching system with high-density panel spacing, 360-degree EMI shielding, and quick mating or unmating. This LEMO push-pull connector series is designed for indoor or vacuum-tight applications, making it an ideal choice for test and measurement instrumentation, medical devices, research, audio/video, and applications where a highly reliable, quick-mating connector is needed. Modular insert configurations include a wide range of high-density or hybrid electrical contacts, including solder, crimp, PCB straight or elbow, fiber, coax, thermocouple, pneumatic, fluidic, or high-voltage contacts. LEMO’s proprietary keying system allows for a higher contact density while preventing mismating. This LEMO push-pull connector series includes the family size range of 0B to 5B. PEI-Genesis’ Value Add Services are available for the LEMO B-Series with rapid turnaround. Contact us today to discuss your next application.

Electrical Data

Test Voltage (Ue)

Test Voltage is dependant on contact and shell size, along with Insert Configuration.
See Insert Configuration Table.

It corresponds to 75% of the mean breakdown voltage.
Test voltage is applied at 500 V/s and the test duration is 1 minute.
This test has been carried out with a mated plug and socket, with power supply only on the plug end.

Operating Voltage (Us):

It is proposed according to the following ratio : Us = Ue/3

Voltage values are given in the table on insulator types for each series.

They correspond with values measured at sea level.
They are adapted to all applications up to an altitude of 2000m.

In case a device is used at a higher altitude, air clearance between live parts has to be multiplied by the following coefficients.
It means also that test voltage has to be divided by this coefficients.

Electrical Data - Current Rating

Current Rating is dependant on contact and shell size, along with Insert Configuration.
See Insert Configuration Table.

The specified rated current can be applied simultaneously to all the contacts. It corresponds with an average temperature rise of 40°C of the connector.

Mechanical

*Steam sterilization

Contact Resistance with Relation to the Number of Mating Cycles
Average values measured after the mating cycles and the salt spray test according to IEC 60512-6 test 11f.

Insulation Resistance Between the Contacts and Contact/Shell

Note: 1) 21 days at 95% RH according to IEC 60068-2-3.

Contact Retention Force - Crimp Contacts
Solder contacts are pressed fit and will have higher retention force.
