SKI

The SKI is the slimline version of a safety switch with separate

actuator. It is based on the BERNSTEIN I88 family. Its dimensions,

not including the actuating head, correspond to EN 50047.

The actuating head is rotary mounted and has two actuator

openings. The SKI safety switch is predestined for installation on

section structures and in applications with confined installation

conditions. Compared to the SKT, it offers more connection space

for the wiring and variants with up to three switching contacts

are available.

Other advantages of this series include:

z Integrated eject function (FE):

The actuator is ejected if the door is not locked securely.

Consequently, the safety contact is opened, thus preventing

the machine from starting up. In addition, this function makes

it apparent that the door still needs to be locked.

z Actuating force (up to 50 N):

The standard actuating force is 10 N. Depending on the switch

variant, an actuating force of 50 N can also be selected. In many

applications, hatches and doors need to be secured to prevent

them being opened unintentionally. This is achieved by means

of bolts, fasteners or other latching mechanisms. The SKI safety

switch should be selected for applications requiring increased

actuating force.

z Universal radius actuator (MRU):

The MRU actuator is ideally suited for applications where the

installation conditions severely restrict the actuating travel or

radius. It has an adjustable actuating radius in the horizontal

and vertical plane.

SKC

In terms of lengths, the SKC safety position switch is the 15 mm

shorter variant of the SK. This makes it the right choice for confined

installation conditions.

The SKC otherwise offers the same advantages as the SK:

Industrial standard with particular emphasis on safety, personal

protection, variable actuator head with two actuator openings.

Other decisive advantages include:

z Different actuating forces:

Corresponding to your specific application, in addition to

the standard 10 N, you can also choose an actuating force

of 5, 20, 30 or 50 N.

Actuating forces from 30 to 100 N can be realised with the

aid of additional components that are mounted on the out-

side of the switch.

z Anti-tamper facility:

The switching system is protected by multiple coding to ensure

enhanced safety of your application.

z Outstanding handling:

With the two slots you can easily adjust the SKC safety switch

and lock it in position by means of the two holes accessible

from the top or the two holes accessible from the front. The

switch can be wired from three different sides. A transparent

cover prevents foreign particles from entering the contact

space while connecting the power supply cable.

Actuator: metal

The SK safety position switch is an industry standard and can

be used in virtually any application.

Thanks to design safety features conforming to VDE 0660 T200,

IEC 60947-5-1 and the test regulations GS-ET 15, the SK is parti-

cularly suitable for personal protection applications. Its versatility

is enhanced by the variable actuator head and two actuator

openings.

Other decisive advantages include:

z Different actuating forces:

Corresponding to your specific application, in addition to

the standard 10 N, you can also choose an actuating force

of 5, 20 or 30 N.

can be wired from three different sides. A transparent cover

prevents foreign particles from entering the contact space while

Switch with VTW, VTU, VT actuator

Variable VTU head

These position switches of the tried-and-tested switch

families I88, ENK, ENM2 and GC correspond to Type 2.

This means that you can use Type 1 and Type 2 position

switches corresponding to your applications while using

one family of switches.

ENM-VTW ENK-VTU

This results in many advantages:

z Standardisation:

Switches of one family have the same mounting dimensions

and the same electrical properties.

z Reduced costs:

II88, ENK, ENM2 and GC are used in large quantities. This not

only reflects the quality of the products but also means lower

prices compared to special designs used in small quantities.

Repositioning the actuator head either in horizontal or

vertical direction results in 8 approach actuator directions.

SLK

Safety Switches with Separate Actuator and Interlock

Machines that continue running after being

switched off are often part of automated

production processes. Safety guards pre-

vent operator access and must therefore

be kept closed until the hazards posed by

machine movement have ceased.

Safety position switches with interlock

function ensure that safety gates, safety

doors and other protective guards remain

closed for as long as a hazardous situation

exists.

In production processes safety position

switches have three main tasks:

z Enabling the machine/process when the

safety guard is closed and interlocked

z Disabling the machine/process when

the safety guard is opened

z Position monitoring of the safety guard

and interlock

The SLK/SLM safety position switches with

separate actuators and interlock enable the

user to realise locking systems conforming

to EN 1088, EN ISO 12100-1, 12100-2 and

since 29.12.2009 to the compulsory Machi-

nery Directive 2006/42/EC.

System description

SLK/SLM safety position switches with inter-

lock function are available in versions with

spring force locking action and magnetic

force locking action. The separate actuator

is connected form-fit with the safety guard.

It transfers the locking force to the safety

guard and monitors its position. Thanks to

its triple coding, the separate actuator ensures

a high degree of anti-tamper security. The

interlock facility in association with the SLK/

SLM safety position switches is integrated

in the switch enclosure. To lock the actuator

in connection with a switching mechanism,

the required interlock is achieved by means

of a spring mechanism in the spring-force

locked version and by an electromagnet in

the magnetic-force locked version.

Locking principle

Spring force (closed-circuit current)

The safety guard is locked automatically

when the actuator is inserted to its end

position. It is unlocked by energising the

electromagnet, allowing the safety guard

to be opened.

Magnetic force (working current)

The lock (interlock) is deactivated when

the electromagnet is de-energised, in the

event of fault in actuation or power failure.

The safety guard can be opened.

Product advantages

z Two independent safety circuits ensure

reliable integration

  zWith two contacts, circuit

  zWith two contacts, circuit

The contact configuration is

variable and may deviate from

the selection table if required.

z Two different operating voltages

for universal integration::

  z24 V AC / DC

z110 V / 230 V AC

z Rotary actuating head (4x 90°) as well

as horizontal and vertical actuation

ensure complete flexibility in use

z Compact design with short overall size

z Innovative installation with

spring-loaded terminals

z Function conforming to GS ET 19,

EN 60 204-1, EN 60 947-1 and

EN 60 947-5-1

Safe operation

The stainless steel actuator ensures safe

and reliable operation. Its coding prevents

tampering and bypassing the system

„in an easier way“. The radius actuator is

ideal for monitoring smaller safety gates.

It can be preset horizontally or vertically

and is also made from stainless steel.

Innovative installation

The SLK is electrically connected safely

and reliably by means of terminals. Spring-

loaded terminals are used, into which the

wires with ferrules can be inserted with-

out the need for tools. The fact that the

connection compartment is separate from

the functional parts contributes to ensuring

secure and reliable connection. The connec-

tion compartment conforms to protection

class IP67.

Flexible in use

The SLK safety switch can be actuated

in horizontal and vertical direction. Prior

to installation it is preset by simply repo-

sitioning the head section.This flexibility

in installation is achieved by positioning

the actuator head in steps of 4 x 90°.

IMPORTANT: The actuator for the SLK must be ordered separately. You will find a corresponding overview on Pages 96-97.

The actuator is not included and must be ordered separately.
