Eaton Limit Switches - LS-Titan Metal Body Series

The LS-Titan range of key interlock limit switches from Eaton is designed for monitoring the position of protective guards, such as doors, flaps, hoods and grilles. These switches are safety rated and include positive opening NC contacts meaning they cannot be defeated using basic tools such as pliers, screwdrivers and nails.

The LS-Titan range of limit switches includes 3 safety limit switch types: key interlock, door flap and door hinge switches. The key interlock switches are made up of the switch and the actuator (or key). The switch is mounted to a rigid section of the machine while the actuator is fixed to a movable guard. By opening the guard the actuator is no longer in physical contact with the switch, therefore positively breaking the NC contacts which interrupts the electrical control circuit, stopping the machine.

Door flap and door hinge limit switches are suitable when mounting actuator in the application is not possible. When an attempt is made to open the protected door hinge or flap during operation these limit switch systems automatically disconnect the power supply.

Eaton LS-Titan metal body limit switches provide high personnel and process protection in industrial control applications. Designed for use in safety circuits, the limit switches are quickly installed, are flexible and safe whilst offering high reliability and durability.

Eaton Limit Switch, Slow Action, SPDT Configuration - LS-Titan Series - 266144LSM-11

Precisely control your protective enclosures with this limit switch from Eaton. Its rounded plunger actuator gives you a broad pushing surface, so it's safe and responsive in applications with short machine movements. The bright yellow colour also makes it easy to spot. An IP67 rating means this switch is protected from dust and limited water submersion, which makes it suitable for use in hose-down industrial conditions. This switch supports AC voltages up to 415V and DC connections up to 220V, so it's widely compatible with common power supplies.

• Resilient die-cast zinc casing is resistant to corrosion for use in damp conditions
• Compact length of 76mm means it's suitable for mounting in small spaces
• Long mechanical service life of around 8 million operations means it's sustainable and cost-efficient
• Withstands short circuits up to 1kA so it keeps working after power surges

Why should I choose a slow-action limit switch?

While a snap-action switch is faster, a slow-action limit switch is suitable for applications that need to be activated with caution. This type of switch relies on the movement of its actuator to work, so it's better suited to processes with slower machines.
