FAQ - General
- My equipment has a LEMO multi-pin receptacle and I need the mating plug. How do I determine the LEMO part number I need?
- Are LEMO connector design trademark registered?
- Can I determine a full part number from partial data on my LEMO plug or receptacle?
- How does LEMO determine the maximum recommended operating voltage?
- Can I download PDF drawings of LEMO connector from this web site?
- My equipment has a LEMO receptacle with a concentric contact, how do I determine the part number?
- Does LEMO have BNC adaptors?
- What is a cable group?
- What type of thread lock material may I use on REDEL® connectors?
- How do I know if I have a LEMO connector?
- Does LEMO offer customer specific stocking programs?
- How do I order my plug with a bend relief?
Before LEMO can assist with a mating plug part number, we must first identify the LEMO receptacle.
First, check your equipment documentation to see if the LEMO part number is included.
If not, check the equipment manufacturer's web site to determine if they reference this information.
If the first two steps do not yield a LEMO part number download a Receptacle Identification Guide for more assistance.
Yes. LEMO's distinctive "chocolate plate" connector design is a registered trademark US Reg 2'703'464 and Europe Registration 798'106
The mark consists "...of truncated pyramidal projections formed on an outer surface of a connector, and with each truncated pyramidal projection having a square based on a square top"
The 5th letter of a LEMO part number is an indication of the connector series. Other information needed to determine a full part number is as follows: How many contacts (pins) are in the insert of the connector? Is the shell soft chrome plated brass shell? Are the terminations solder or crimp? What is the diameter of the cable entering the rear of the connector (in millimeters if possible)? Is there a bend relief (strain relief) at the transition of the connector to the cable? Color?
See Part Numbers Explained for more information about LEMO's part numbering system.
LEMO determines its published Operating Voltage V(signal) specifications as follows:
V(test) = 0.75 x V(breakdown)
V(signal) < 1/3 x V(test)
V(breakdown) = Mean breakdown voltage
V(test) = Test Voltage
Substituting V(test) in equation (2) through V(test)
from equation (1) yields equation (3):
V(signal) = 1/3 x 0.75 x V(breakdown) = 1/4V(breakdown)
