Snap Action, Limit Switches - D4A-1110-N

The D4A-1110-N is a snap action limit switch manufactured by Omron. It is a micro switch ideally suited for use in areas with space limitations. This limit switch has a wide range of applications, including the reliable detection of the end points of automated machinery, such as automated door openers, vending machines, and packaging equipment. The switch is also used in other applications such as HVAC control systems and in machine tools.

Features

The D4A-1110-N has a number of features that make it an ideal choice for both industrial and home automation applications. The switch has a long service life, up to 1 million operations, and is rated for a maximum of 5 million operations. It also has a wide operating temperature range, from -30 to 70°C (-22 to 158°F). Additionally, it has a base plate measuring 22mm x 22mm (0.87” x 0.87”), and a height of just 10.5mm (0.41”), making it suitable for installation in tight spaces.

Working principle

The D4A-1110-N limit switch utilizes a snap action mechanism. This means that when there is an actuating force applied to the device, it snaps into the ON position, and when the force is released, it snaps back to the OFF position. This makes it ideal for use in applications which must switch rapidly from one state to the other in order to operate at maximum efficiency. The switch functions by opening and closing an electrical circuit when tripped by an actuating force, such as a lever or plunger.

Safety Considerations

As with all electrical devices, care should be taken when working with the D4A-1110-N limit switch. Proper precautions should be taken to ensure the safety of equipment, personnel, and environment when working with the switch. Additionally, this switch should be tested before use to ensure that it is functioning properly.

Applications

The D4A-1110-N is widely used in automotive, industrial, and home automation applications. It is also suitable for use in HVAC and machine tool applications. Some of the more common applications include door openers, vending machines, and packaging equipment, as well as switches used to control motors and other electrical devices.

Conclusion

The D4A-1110-N is a snap action limit switch manufactured by Omron, is ideally suited for use in areas with space limitations. This switch has a wide range of applications, including the reliable detection of the end points of automated machinery. With a long service life, a wide operating temperature range, and a small size, this switch is an ideal choice for a number of applications, from automotive and industrial to home automation.
