This document provides information about reed switches, SMD reed switches, reed sensors, level sensors, and magnets from PIC GmbH. It includes specifications, features, dimensions, and characteristics for various product lines and models. The core products are reed switches and reed sensors, which use magnets to actuate a pair of ferromagnetic reeds sealed in glass tubes for non-contact switching applications. SMD versions are also available for direct mounting to PCBs. Level sensors incorporate reed switches or sensors into housings for liquid level detection. Customized solutions include special housings, connectors, and assemblies.

2. Welcome to PIC
Our work is never done.
Passion, respect, integrity and
discipline are the four core values
which drive us to sophisticated
products and continuous growth
in a globalized world.
Innovation
Modern machinery, perfected production
concepts, clear information policy and our
comprehensive sensor know-how secure
our premier position in the branch.
Product Innovation
Intelligent Design
Creative Manufacturing
Quality
Continuous optimization in the areas
of research, development, production,
service and marketing assure high
standards in product quality.
Sustainability
Sustainability is an essential part of our
philosphy. Careful use of resources and
environmental compatibility starts long
before production and does not finish at
sale. We remain true to this principle with
regard to social and economic aspects.

A Level Sensor incorporates a Reed Switch in
a stem. An external float, with a magnet inside,
passes and actuates the Reed Switch, depending
on liquid level.
Actuation principles for Reed Switches also apply

Tech Center: Reed Switches
How to operate
Precautions
In general four different magnet approaches
are known when using permanent magnets
1
One magnet pole faces Reed Switch providing
two operations max. when moving on X-axis.
Minimum movement of magnet over switch
center provides smallest possible switching
differential.
2
OFF
Y
HOLD
Magnet parallel to longitudinal axis of switch:
Approaching magnet vertically to switch on
Y-axis provides one operation only.
Driving magnet over full length of switch (Xaxis) may result in up to three operations.
Minimum movement of magnet over switch
center provides smallest possible switching
differential.
ON
Generally Reed Switches provide high shock resistance up to 100 g. Still a
drop on a hard surface can generate a shock of several 100 g, which can lead
to de-adjustment of contacts. Switches having been dropped should be
re-tested for sensitivity before usage!
Do’s and Don’ts when cutting and bending Reed Switches
Y
HOLD
Incorrect bending or cutting of
terminals may lead to cracks in
the sealing area due to heavy
mechanical stress. To avoid this
problem the remaining part of
terminal between glass body and
point of bending resp. cutting,
should be gripped tightly.

Switch operation by rotation of magnet.
This gives two operations per complete
rotation.

Forces directed away from Reed Switch
Operation of switch by shielding. This method
requires a permanently opposite location of
magnet and switch. The switch is held closed
continuously and will release only if magnet flux
is removed by means of ferro-magnetic shield.
