Snap Action, Limit Switches: TFCGK6ST1840Y

Snap action, limit switches dynamically switch when a predetermined point is reached and are available in a range of configurations, such as single throw and double throw. The TFCGK6ST1840Y is a double-wound spring type snap-acting switch, designed for applications requiring reliable operation and a long service life. This switch is protected by a black steel cover with a transparent window and is rated for a maximum current of 10 amperes, at 10 watt power.

Application Field

The TFCGK6ST1840Y switch is used for position and presence limit applications, such as with automated industrial equipment, workshops, laboratories, and in biomedical and electrical engineering applications, where it is used for signal control and switching. The terminals are DIN-rail mounted, making it ideal for connecting with a range of cable types, for motor, solenoid and relay switching, level monitoring and mechanical power limit applications.

Operating Principle

The TFCGK6ST1840Y switch is designed to offer precise, precise and adjustable switch positions. A steel plate spring combination and a PIR lens (which act as a contacts) are the two main components of this switch. The PIR lens can be adjusted to three different positions, and allows the user to set the switch to a rapid, slow contact closure or non-contact mode. Additionally, the spring plate combination provides a fast reaction time and an adjustable force that is applied to the PIR lens, enabling the switch to adjust to various contact forces.

When the TFCGK6ST1840Y switch is operating, a plunger is pushed by an external force against the steel plate spring combination and the PIR lens, which then closes the contacts. The plunger is specially designed to reduce the force required for successful contact closure and to ensure electrical continuity for reliability and long-term operation. The PIR lens is highly sensitive and allows for smooth and consistent switch operation.

Safety Features

The TFCGK6ST1840Y switch is designed to provide safety features which are essential for the protection of the switch and of the people operating it. The transparent window prevents accidental short circuit and protects against liquids and debris, while the robust steel cover shields against mechanical load, electrical interference, and wide temperature fluctuations. The steel cover also ensures that high levels of insulation are maintained, further improving the safety of the motor, solenoid and relay connections.

The TFCGK6ST1840Y features is also certified for use in various hazardous locations, making it suitable for applications such as transportation, production and power-generating stations. It can manage a wide range of gas and dust concentrations and an over-temperature range of -130° to 430°.

Additional Specifications

The TFCGK6ST1840Y switch is rated IP54, meaning that it is dust-protected and water-resistant. It supports a voltage range of 12V to 415V, while providing operating temperature range of -30° to 125°, and lug hole connections that are designed to accommodate a range of connection hardware.

Overall, the TFCGK6ST1840Y double-wound spring type snap-acting switch is suitable for use in a wide range of limit and position applications. It combines reliable operation, long-term performance, and robust safety features for a safe, secure and efficient switch solution.
