SIRIUS 3SE5 Mechanical Position Switches
General data
12
■
Overview
The innovative SIRIUS 3SE5 position switches are modern in
design, compact, modular and simple to connect. They save
time and increase flexibility during installation of a whole range
of switch variants. In principle it is possible to combine any
enclosure with any operating mechanism, paying due consider-
ation to the EN 50041 and EN 50047 standards where
necessary.
Complete units
Popular versions of the position switches in standard enclosures
are available as complete units.
3SE5 position switches with plastic and metal enclosures
Modular system
The 3SE5 series is the modular system comprising different
sizes of the basic switch and an actuator which must be ordered
separately. Thanks to the modular design of the switch the user
can select the right solution for his application from numerous
versions and install it himself in a very short time.
Simple plug-in mounting enables fast replacement of the
actuator heads.
Examples of selection options in the modular system
Design
All enclosure variants have an integrated chlorinated rubber
diaphragm for high functional safety in cold and aggressive
environments.
Enclosure sizes
The 3SE5 switches are available in five different enclosure sizes
with 2 or 3 contacts and with the XL enclosure:
•Open-type position switch IP20 or IP10
•Plastic enclosures according to EN 50047, 31 mm wide, IP65,
1 cable entry
•Metal enclosure according to EN 50047, 31 mm wide,
IP66/IP67, 1 cable entry
•Plastic and metal enclosures according to EN 50041, 40 mm
wide, IP66/IP67, 1 cable entry
•Plastic enclosure, 50 mm wide, IP66/IP67, 2 cable entries
•Metal enclosure, 56 mm wide, IP66/IP67, 3 cable entries
•XL metal enclosure with 4 to 6 contacts, 56 mm wide,
IP66/IP67, 3 cable entries
Enclosure versions
Various basic switches can be selected for the enclosures of the
3SE5 series:
•
With contact blocks with two or three contacts (screw
terminals) designed as slow-action or snap-action contacts;
the slow-action contacts also with make-before-break
•
Optional LED status display
•
With mounted four- or five-pole M12 connector socket
(available for the wide enclosures as an accessory for
self-assembly)
•
With 6-pole connector socket + PE on the metal enclosures
•
Versions with increased corrosion protection
•
Versions for operating temperatures down to –40 °C
•
AS-Interface version with integrated ASIsafe electronics for all
enclosure designs
(see page 12/91)
Actuator variants
All operating mechanisms can be rotated around the axis in
increments of 22.5°. The following actuator variants are
available:
•
Standard, rounded and roller plungers
•
Roller levers and angular roller levers
•
Spring rod
•
Twist levers and rod actuators with twist lever actuator
•
Fork levers with twist lever actuator
The actuator rollers are available with various materials and
diameters.
Twist actuators for twist levers and rod levers,
with setting of switching direction to right, left, or right/left
(standard for all twist lever actuators except fork levers)
