1DM171

The 1DM171 is a type of limit switch referred to as snap-action. Limit switches are electromechanical physical devices used to detect and control the movement of machines and objects, such as a door latch opening/closing, a conveyor part stopping/starting, and machine brakes operating/releasing. Limit switches are an economical and reliable choice for most sensing needs.As the name implies, snap-action switches are designed to "snap" from one state to another, such as an open position to a closed position or vice versa. 1DM171 is designed like this and is a spring-type limit switch. It contains a housing, a spring, a contact, and a plunger or lever. When an actuating force is applied to the plunger, the spring compresses, and when the actuating force is removed, the spring extends, allowing the switch to revert to its original position. In this way, the contact can be opened or closed chronologically.The 1DM171 is capable of switching twice the maximum rated current of a nonSpring lever type and is compact-sized and cost-effective. It offers excellent operation with a good repeatability and repeatability. It has superior protection against electric shocks, as well as dust and water resistance. It is durable and resists wear, making it an ideal choice for countless applications, such as industrial machinery, metering systems, elevators and escalators, building automation systems, agricultural machinery, station platforms, and electric vehicles.The working principle of 1DM171 is based on its snap-action design. When a force is applied to the lever, the contact immediately switches its circuit connection and a wiring pressure is established. When the force is removed, the contact releases the circuit connection and reset once again. This alternating process allows the device to be used in many applications as a remote switch.Several features of the 1DM171 make it an advantageous option for certain applications, such as its high speed and reliability. The switch responds quickly to force and can operate up to 300 times per minute, making it ideal for high-speed production lines. It also has inline contact construction with pins perpendicular to the mounting surface, which helps ensure accurate contact alignment and repeatability.The 1DM171 is an ideal choice for a variety of applications, providing excellent operation, accuracy, reliability and performance. This type of limit switch is an excellent option for a wide range of industrial and commercial applications, offering a cost-effective solution for many sensing needs.
