LEMO has a distinguished reputation in offering high-quality, push-pull connectors and cable
assemblies to the medical industry. We have a wide array of both technical and manufacturingexpertise that we bring to our customers to drive future medical device development. A global
company with local service and technical support.
How does the IEC 60601-1 change the design of your Medical Equipment ?
Latest release of IEC 60601 (3rd Ed.) brings protection against electrical hazards to higher
standards. This impacts medical device interconnections in 3 specific aspects which are summarized below:
1. Increased ESD protection threshold form 8 kV to 15 kV.
2. Increased MOPP / MOOP values and re-definition of clearance and creepage requirements.
3. Application of the above improvements to normalized finger tests.
LEMO can help you with:• Advising on cable assembly techniques with solutions such as the use of dielectric barriersin the form of heat shrink tubing on contact terminations.
• Sleeved contacts which increase the separation distance during mated and unmated condition.
• Compliant product with insulation barriers to increase the separation distances at the rear of theconnector. This is also possible with PCB mounted connectors.
• Compact designs making the most efficient use of the space available.

ESD protection (15 kV)
The purpose of Electrostatic Discharge (ESD) protection is to avoid
voltages from medical devices coming into contact with operators.
The new IEC60601-1 (3rd ed.) defines an increased value of 15 kV
as a minimum insulation voltage between conductors and the operator
in a mated condition.
LEMO offers several solutions to achieve this specification:• On the REDEL P series, we can 1) select a thicker dress nut which canalso add IP66 sealing, or 2) utilise high voltage inserts thatsignificantly increase the creepage and clearance distances.
• On the SP series, all models fulfill this requirement due to the design
which features the unique and patented inner locking mechanism.

Means of protection
Medical devices must incorporate two Means of Protection (MOP)
to isolate patients and operators from the risks of electrocution.
A MOP can be safety insulation, a protective earth, a defined creepage
distance, or an air gap (clearance). These can be used in variouscombinations.
The IEC 60601-1 (3rd ed.) differentiates between the risk to patientsand the risk to operators. A MOP can therefore be classified as
Means of Patient Protection (MOPP) or a Means of Operator
Protection (MOOP).
When applied to connectors the typical values to consider for MOOP
/ MOPP compliance are pin to pin creepage and clearances distances
defined for several voltage classes in the IEC 60601 (3rd ed.) standard.
LEMO offers several models with specially qualified inserts in both
REDEL 1P or 2P series.

Test finger

Standard gender, power supplied from socket

Finger test conformity is the 3 aspect of operator and patient protection
as the design guarantees that no access is possible to the electricalcontacts. This geometrical barrier prevents the risk of electrical shock
when unmated. The test is performed using the normalized test finger
according to IEC 61032. Although our compliant inserts offer protection,
care should be taken in designing the system with consideration given
to the direction of current or voltage. For example, supplying the power
through the less accessible side or socket style contacts. LEMO offers
most of its configurations in both standard and reverse gender allowing
customers maximum flexibility in their design.

Cable assemblies and custom solutions®

Cable assembly
The cable assembly depends essentially on the application.
Typical applications related questions could be:• Will the connector and its associated cable be manipulated over
and over again by an operator?
• Does the assembly need to be watertight?
• Is there a specific standard that the assembly needs to meetor conform to?
• Are there operations or conditions that the assembly will encounterthat could affect the design such as the flexibility or the way the cablelies within the environment?
• And more.

LEMO’s skilled technicians will consider all these questions and propose
assemblies to be manufactured to customer specifications.
