Introduction

Snap action limit switches are mechanical devices used in automation applications. They are used to detect or limit the travel of a movable part of a machine. TL5012-2110SM is a snap action limit switch developed by Panasonic. This device is equipped with a single-pole double-throw (SPDT) contact mechanism, which is suitable for a variety of applications requiring detection or limitation of movement.

Application Field

The TL5012-2110SM Snap Action limit switch is ideal for applications that require highly reliable electrical staging or limit point detection/control, as well as a tightly sealed structure to protect from dust and water. With its robust and durable enclosure and mechanical components, it is suitable for automation applications in factories and in harsh environments. It is used for detecting the presence of a machine element such as a door, shaft, lever, or actuating cylinder. It can also be used in medical devices and assembly lines.

Working Principle

The TL5012-2110SM snap action switch works according to the principle of mechanical overtravel. The device consists of a movable button/lever and a stationary contacts/washboard. When the moving parts move past a certain point, the stationary contacts or washboard contacts the button/lever and close the circuit. When the moving parts moves back, the button/lever is released, and the electrical circuit is opened again. The TL5012-2110SM switch works in three stages: the approach stage, the overtravel stage and the separation stage. In the approach stage, the moving parts move close to the switch contacts and cause them to close. Moving parts approach the switch and the contacts remain closed until contact pressure reaches a predetermined amount, after which contact closure is released. In the overtravel stage, the contacts snap open and the switch is disengaged. As the moving parts separate, the switch contacts snap shut and the electrical circuit is broken again. When the moving parts move past a certain point, the stationary contacts on the washboard activate the lever, which then moves and contacts the switch contacts. This causes the contact switch to close, thus creating a circuit. The contact switch will remain closed until the moving parts separate from the stationary contacts, at which point the contact switch will open. The TL5012-2110SM switch is designed for accuracy, reliability and durability. It is designed to meet the highest quality standards, including a capacitance range of 0-50 μF and a contact resistance of less than 30 mΩ. The switch also has a maximum mechanical life of up to 50 million operations.

Conclusion

The TL5012-2110SM is a snap action limit switch from Panasonic. It is ideal for applications such as detecting and limiting the travel of a machine element, assembly lines and medical equipment. The switch works according to the principle of mechanical overtravel, with three stages – approach, overtravel and separation. It is designed for accuracy, reliability and durability, with a capacitance range of 0-50 μF and a contact resistance of less than 30 mΩ. The TL5012-2110SM is a great choice when a tightly sealed switch with a long life expectancy is needed.
