Safety switch TZ with guard locking and guard lock monitoring
Approach direction
Horizontal
Can be adjusted in 90° steps.
Mechanical release
Is used for releasing the guard locking with the
aid of a tool. A sealing wire can be fitted to
protect against tampering. Lead sealing kit and
tool included (already pre-assembled on versions
with plug connectors).
Solenoid operating voltage and LED
function display
The following voltage ranges are available:
24 V AC/DC -15%, +10%
110 V AC -15%, +10%
230 V AC -15%, +10%
Guard locking types
TZ1 Closed-circuit current principle, guard locking
by spring force. Release by applying
voltage to the solenoid.
TZ2 Open-circuit current principle, guard locking
by applying voltage to the solenoid.
Release by spring force.
Switching elements (see also page 13/14)
SK For monitoring the door/actuator position
ÜK For monitoring the guard locking (built-in solenoid)

About this catalog
The catalog Safety switches with Metal housing provides an overview of
our
safety switches with metal housings in the series N1A, NB01, NZ,
TZ, NX, TX, STA and the safety hinge ESH. For numerous applications
these switches are the right choice due to their robustness and long
service life.
You will find the technical data after the product overview. There is a
reference to the page with the related technical data on the pages listing
the products.
At the front of the catalog you will find useful information on the topic of
safety switches.
We have prepared an overview of the standards and a glossary on this
topic in the appendix.
You will also find important safety instructions in the appendix.
How can I find the right switch?
There are two ways you can find the right switch:
If you know the order number or the product designation, look for
the switch directly in the item index (see page 206 or page 213).
You will find the following series and accessories in this catalog:
If you have specific requirements, refine the selection step-by-step
with the aid of the table of contents and the selection tables.
