2 .3 Limit Switches Product Description Features Eaton s LS-Titan limit switch line is a complete offering of safety position switches designed for worldwide application. Economical insulated plastic or rugged metal enclosures and modular, plug-in operating heads and bodies make LS-Titan a flexible switching solution. A highlight of the LS-Titan switch line is the world s first electronic position switch (LSE models). These switches feature freely programmable operating points that can be set individually at any time. Additional LSE models provide analog outputs proportional to the actuator position. LS-Titan switches are suitable for use in safety applications designed to protect persons or processes. For the most current information on this product, visit our web site: Modular, plug-in system (head and body components) Positive opening contacts for safety applications Wide variety of economical plastic and rugged metal versions available Operating heads can be rotated 9 degrees to suit specific direction of operation Unique electronic safety position switches (LSE models) provide analog ( 1 Vdc or 4 2 ma) outputs proportional to the actuator position and allow for easy configuration of a custom trip point Contents Description Page Product Identification Product Selection LS-Titan Plastic Safety Switches LS-Titan Plastic Electronic Safety Position Switches LS-Titan Metal Safety Switches Understanding LS-Titan Electronic Safety Position Switches Operating Point Adjustment Accessories Technical Data and Specifications Contact Travel Diagrams Dimensions Can be ordered as separate components (head and body) or as completely assembled switches Screw and Cage Clamp (standard on LSE models and optionally available on mechanical models) connections provide larger wiring areas for easier installation Approved for worldwide application Standards and Certifications Safety function by positive opening contacts per IEC/EN up to Category 4 per EN TÜV-Rheinland Certified for Functional-Safety (LSE models) CSA certified UL listed CE CCC Note: Cage Clamp is a registered trademark of Wago Kontakttechnik, Minden, Germany. 2 LS-Titan Products CA5283E January 211

13 Limit Switches.3 Understanding LS-Titan Electronic Safety Position Switches All four LS-Titan LSE switch bodies are safety-rated products. The LSE-11 and LSE-2 switch bodies both have a freely programmable operating point and can be individually adjusted to suit the application, and can be changed as often as required. These devices feature an LED on the body, providing simple indication during programming and operation. Operating Point Adjustment LSE-11 The LSE-AI (4 2 ma) and LSE-AU ( 1V) analog position switches take position data and convert to an analog current or voltage value that can then be continuously fed into an automation system. These two switches also feature a diagnostic output for additional data processing.

24 .1 Safety Products LS-Titan Safety Interlock Switches LS-Titan Safety Interlock Switches LS-Titan Safety Interlock Switches Product Description Eaton s LS-Titan safety interlock switches have been specifically designed for monitoring the position of protective guards, such as doors, flaps, hoods and grilles. All switches in this family are safety-rated, include positively opening contacts, and cannot be defeated using simple tools, such as pliers, screwdrivers and nails. The LS-Titan safety interlock family is comprised of three types of safety switches: key interlock, door-flap and doorhinge switches. Key interlock switches are a two-piece design, made up of the switch and key (actuator). The key portion of the switch is affixed to a movable door, cover or other such guard. The switch itself is mounted to a rigid portion of the machine. When the guard is opened, the key is removed from the switch, thereby positively breaking the contacts. This interrupts the control circuit, stopping machine operation. For the most current information on this product, visit our web site: The door-flap and door-hinge switches are one-piece designs, suitable for when a key cannot be mounted in the application. When an attempt is made to open a protected door hinge or flap during operation, these switches disconnect the power supply to the machine or installation. Both switches feature fourway adjustable heads. All LS-Titan safety interlock switches are approved to protect personnel and processes.

Any change to an original Eaton safety position switch is not permitted and automatically leads to the loss of all approvals. Switch must never be used as a mechanical stop. 24 LS-Titan Products CA5283E January 211
