3SE International Limit Switches
Position Switches
3SE2 100 to 3SE3 170 / 3SE2 303 / 3SE2 404
Metal enclosure and open type
Features
• UL Listed, CSA Certified, CE.
Meets or exceeds most local,
national and international
standards.
• Standard (40 mm) or Wide (56
mm) die-cast aluminum
housing. Offers increased
wiring space, additional cable
entry options and corrosion
resistant housing
• Standard (40 mm) offerings
can accomodate both U.S.
29.4 [1.16] × 59.5 [2.34] and
DIN 30 [1.18] × 60 [2.36]
mounting dimensions
• Nine field interchangeable
operating heads (12
variations). Interchangeable
on both the standard (40 mm)
and wide (56 mm) styles.
Reduces inventory and
inventory costs
• Field replaceable, electrically
isolated, double bridge
contacts. Provides electrical
flexibility and ease of
maintenance
• Direct opening action (positive
opening) of the NC contact
• NEMA A600, Q600 contact
ratings
Application
The function of position switches
(limit switches) is to produce
electrical signals corresponding
www.DataSheet4U.ctoomthe positions of moving ma-
chinery.
The units are suitable for use in
virtually any climate.
Specifications
IEC 60 947-5-1.
The 3SE2 100 and 3SE2 120 po-
sition switches correspond to
Swiss regulations (SUVA). The
following actuator types have
been approved:
• Plunger
• Overtravel plunger
• Roller plunger
• Roller lever
• Angular roller lever
• Roller crank

In addition, the open-type 3SE3
position switches and the 3SE3
switch inserts are also permit-
ted.
Safety position switches
The 3SE. position switches with
metal enclosures and snap-ac-
tion contacts as well as devices
with slow-action contacts can be
used as safety position switches
in control systems conforming to
EN 60 204-1, or IEC 60 204-1.
Construction
3SE position switches are avail-
able in die-cast standard (40
mm) or wide (50 mm) aluminum
enclosures or as open-type
units.
The 3SE2 120/3SE3 170 position
switches with standard enclo-
sure, overtravel plunger, roller
plunger, rod and roller crank ac-
tuators, conform to EN 50 041.
These specifications define the
most important mounting dimen-
sions, operating points, enclo-
sure types and actuator types.
Position switches have one or
three cable entries. The cable
entry has a 1/2”-NPT (3SE3) or
M20 x 1.5 (3SE2) threaded
metal wire opening. (see also
Accessories, Page 13/97)
Actuators
All actuators can be retro-fitted
or exchanged for another ver-
sion. They can also be reposi-
tioned every 90° so that the
switches can be operated from
any of the four sides.
• The position switches with
roller lever are approached
perpendicular to the plunger
axis and position switches with
angular roller lever are ap-
proached in parallel with the
plunger axis.
• The roller crank actuators, ad-
justable-length roller crank actu-
ators and rod actuators can be
operated from both sides and
be positioned from 10° to 10° on
the actuating spindle. The roll-
ers of the actuators are made
from wear resistant plastic.
• The wobble spring can be ap-
proached from any direction.
• The forked lever actuator has
two defined switching posi-
tions. The actuating element
causes changeover from one
position to the other. This actu-
ator is suitable for two-channel
operation.
The open-type 3SE. position
switches are available exclu-
sively with a plunger actuator.
Important:
The 3SE. position switches with
metal enclosure are not permit-
ted to be used as stops.
Contacts
The position switches (limit
switches) are available with
snap-action contacts, slow-ac-
tion contacts or slow-action
make-before-break contacts.
The 3SE. position switches with
a metal enclosure are available
with 2, 3 or 4 contacts.
The movable normally closed
and normally open switch con-
tacts are electrically isolated
from each other and are suitable
for switching voltages of differ-
ent potentials.
Contact reliability
The movable switch contacts
are double moving contacts.
This increases the contact reli-
ability even when the switch has
to be operated with low voltages
and currents, e. g. DC 5 V/1 mA.
The switching point of the snap
action contacts is independent
of the switching speed.
The contact chamber is covered
to prevent ingress of foreign
bodies.
Principle of operation
Positive opening
The opening contacts of the
switch are forced open mechan-
ically, positively-driven and reli-
ably by the plunger (positive-
opening).
In order to ensure this positive
opening, the position switch
must be actuated in such a way
that the nominal travel (Pages
13/100 to 13/112) and angle for
the positive opening are sub-
stantially exceeded.
Position switches that display
this symbol are suitable for use
in safety applications.
