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. Rmin in setting directions 50 mm Actuating forces FE to FI50 Other advantages of this series include: l 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. l 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. l 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.

This makes it the right choice for confined installation conditions.

Thanks to design safety features conforming to VDE 0660 T200, IEC 60947-5-1 and the test regulations GS-ET 15, the SK is particularly suitable for personal protection applications. Its versatility is enhanced by the variable actuator head and two actuator openings.

This results in many advantages: l Standardisation: This means that you can use Type 1 and Type 2 position switches corresponding to your applications while using one family of switches. Switches of one family have the same mounting dimensions and the same electrical properties. l Reduced costs: II88, ENK, ENM2 and GC are used in large quantities.

Safety guards prevent operator access and must therefore be kept closed until the hazards posed by machine movement have ceased. 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 Machinery Directive 2006/42/EC. 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. System description In production processes safety position switches have three main tasks: l Enabling the machine/process when the safety guard is closed and interlocked l Disabling the machine/process when the safety guard is opened l Position monitoring of the safety guard and interlock 90 SLK/SLM safety position switches with interlock 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 l Two independent safety circuits ensure reliable integration l l With two contacts, circuit 1 monitors the actuator With two contacts, circuit 2 monitors the interlock The contact configuration is variable and may deviate from the selection table if required. l Two different operating voltages for universal integration:: l 24 V AC / DC l 110 V / 230 V AC l Rotary actuating head (4x 90) as well as horizontal and vertical actuation ensure complete flexibility in use l Compact design with short overall size of only 170 mm l Innovative installation with spring-loaded terminals l Function conforming to GS ET 19, EN 60 204-1, EN 60 947-1 and EN 60 947-5-1 The actuator is not included and must be ordered separately. Safe operation Innovative installation Flexible in use 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. The SLK is electrically connected safely and reliably by means of terminals. Springloaded terminals are used, into which the wires with ferrules can be inserted without the need for tools. The fact that the connection compartment is separate from the functional parts contributes to ensuring secure and reliable connection. The connection compartment conforms to protection class IP67. The SLK safety switch can be actuated in horizontal and vertical direction. Prior to installation it is preset by simply repositioning 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.
