TL5012-1220SM

Snap Action, Limit Switches

The TL5012-1220SM from Honeywell is a snap action, limit switch, which is a mechanical device used to detect the position of an object. It is usually used to sense the presence and position of a movable object and indicate its location to a motor or actuator. The TL5012-1220SM is an illumination limit switch, which has an integral illuminator. It is designed to be used in equipment where visual confirmation of when the limit switch is turned on is desired.

The TL5012-1220SM has a high-grade chrome-plated steel housing that is corrosion-resistant, making it ideal for use in harsh environments. It has two integral light sources that can illuminate either side of the switch. The snap-action mechanism provides reliable switching action and long life. The low-profile design fits in even the most cramped work spaces and the actuator head is compatible with most popular panel cutouts. It has a SPDT contact form and a capacity of 10A at 125/250VAC and 10A at 28VDC.

Application Field

The TL5012-1220SM is commonly used in a wide variety of applications. Its high-grade chrome-plated steel housing and corrosion-resistant features make it ideal for use in harsh applications. It is often used in automation equipment, machine tools, printing presses, and manufacturing plants. It canbe used to detect the presence or absence of an object, measure distances or heights, and act as a limit or safety switch.

Working Principle

Snap action, limit switches like the TL5012-1220SM, operate on mechanical microswitches. The switch contains several components, including a button or armature, a spring-loaded actuator, and a switch contact. When the switch is pressed, the actuator forces the armature against the switch contact, causing the switch to open or close. The switch is designed so that when the armature is released, it returns quickly to its original position and triggers an electrical connection or disconnection. The switch will remain in this position until the next movement is detected.

Additionally, the TL5012-1220SM uses a snap-action mechanism, which provides reliable switching action and long life. The snap-action mechanism is activated when an object or force exceeds a specific level, causing the switch to open or close. The switch is then held in this position until a new force or object is detected.

Conclusion

The TL5012-1220SM is a snap action, limit switch which is designed to be used in equipment where visual confirmation of the switch is desired. It has a high-grade chrome-plated steel housing, making it ideal for use in harsh environments. It is commonly used in automation equipment, machine tools, printing presses and manufacturing plants, and can be used for a variety of applications such as detecting presence or absence of an object, measuring distances, and acting as safety or limit switches. The TL5012-1220SM uses a snap-action mechanism, which provides reliable switching action and long life.
