D2F-L151 Snap Action Limit Switches

Snap action limit switches are electromechanical devices used to protect electrical systems from damage due to overload or short-circuit conditions. The D2F-L151 is a type of snap action limit switch from Omron Corporation which is a popular choice for many applications.

Application

The two main uses for D2F-L151 switches are protecting electrical systems from overvoltage or current overload and controlling remotely-powered applications. In a power system, these switches can be used to prevent damage to equipment due to an excessive voltage or current condition. In a motor control application, they can be used to sense the position of an object, such as a valve or door, and open or close the circuit to trigger an action.

D2F-L151 switches are also used in industrial automation, communications, and entertainment equipment. They can be used to detect the position of moving parts and detect various states, such as open or closed, in order to control logic functions. In addition, D2F-L151 switches can be used in medical devices, household appliances, and transportation equipment for sensing and controlling various functions.

Working Principle

D2F-L151 switches work using the principle of a spring-loaded latch. A coil of wire is surrounded by a ferromagnetic core, and when a current is applied to the coil, the core attracts the switch armature and releases the latch. This causes the armature to move and make or break an electrical connection. By controlling the current in the coil, the latch can be reset and the switch can be used multiple times.

The operating temperature range of the D2F-L151 limits switch is –30 C to +60 C. It can be used in hazardous environments and is rated at a current of 25 amps, with a voltage range of 12 VDC to 30 VDC. The switch is sealed and dust-proof, making it an ideal choice for outdoor and environmental applications.

Features and Benefits

D2F-L151 switches are versatile, reliable, and easy to install. They can be used in both power and control applications and are rated for hazardous environments. The switches are also silent and have no moving parts, making them more energy-efficient than other types of switches. Additionally, the D2F-L151 is sealed to protect it from dust, water, and other contaminants.

D2F-L151 switches are also highly sensitive and require only a small amount of current to activate. They are highly reliable and durable, making them an ideal choice for many applications. Additionally, they come in a variety of mounting styles, including surface and panel mount, enabling them to be used in tight spaces.

Overall, the D2F-L151 is a reliable and versatile snap action limit switch suitable for a wide range of applications. It is highly resistant to harsh environments and can be used in both control and protect applications. With its small size, low power requirements, and ease of installation, the D2F-L151 is an excellent choice for many applications.
