Safety Switches NM
General Information
The EC Machinery Directive defines measures that reduce to a
minimum the individual dangers and the accident risks associated
with machines and installations that make movements which create
a danger, and in the vicinity of which people may be injured.
If all sources of danger cannot be eliminated by design measures,
appropriate guarding measures have to be taken.
In practice, isolating guard devices are used for this purpose.
These are necessary if frequent access to the hazardous zone is
frequently required.
Access into hazardous zones is required to perform tasks such
as loading and unloading material, troubleshooting, machine setup
and cleaning work.
Safety switches of Design Type 1 and / or Design Type 2 are
used to safeguard access to a hazardous zone accordingly.
The function of these switches is to monitor the moving part of
the guard device and upon removal (opening) of the guard device
to reliably interrupt the electrical circuit and create a safe operating
status.
The new plastic-encapsulated series NM safety switches meet
these requirements fully. With this series EUCHNER supplies safety
switches that are used particularly where extremely small units
are required. In addition, due to its optically highly sophisticated
design, the entire product group of NM switches complies with
the demand for machines with a more modern appearance.

Two basic housings with up to three switch contact elements and
three cable entries are available. The small housing version, with
a positively driven NC contact, is used wherever a simple wiring
concept is sufficient.
The larger housing version giving you two or three contact elements
achieves a higher level of safety.
An extremely high degree of flexibility is guaranteed by the three
possible cable entries (large housing version) and the ability to
turn the actuator head in 90 increments. The generous connection
space (Environmental Protection IP 67) for the switching elements
allows easy handling.
Fixture of the cover with just one cover screw simplifies initial
operation of the switch on the machine.
Besides switches with a cable entry, EUCHNER does of course
also supply the series NM safety switches with M12 connectors.
Due to the plug-in type connection, any wiring defects on the switch
are excluded and fast installation is made possible.
