Snap Action, Limit Switches

The D4BL-2CRA is a snap-action, limit switch manufactured by Omron Automation and Safety, known for its reliable and rugged design. The D4BL-2CRA is a single-pole, double-throw switch that is actuated when a mechanical force is applied. It can be used in many different applications, such as controlling motors and other moving parts, or as a limit or position switch for limitation of movement.

Application Field

The D4BL-2CRA offers a wide variety of uses in both industrial and commercial applications. For industrial use, it can be used to help control motors and other moving parts like pumps, valves, and linear actuators. It can also be used as a limit switch in a conveyor system, or as a position switch in a machine tool. In commercial applications, the D4BL-2CRA can be used in a wide variety of appliances, such as refrigerators, freezers, and vending machines. It can be used to detect an open or closed door in an refrigerator, or to detect when food has been placed into a vending machine. It is also often used to help control the temperature of commercial ovens and fryers.

Working Principle

The D4BL-2CRA is actuated when a mechanical force is applied to the switch. When the switch is triggered, the terminal and movable contact inside the switch close, and an electrical current is passed through the opened switch. This action will depend on the type of switch – normally open or normally closed. The switch is reset when the mechanical force is removed from the contact and the switch is returned to its original state.

The D4BL-2CRA is designed for long life and endurance, and its contact system allows it to maintain low contact resistance over millions of operations. The switch is highly reliable and resistant to shock, vibration, and corrosion, allowing it to operate in harsh environments. The switch’s slim design allows it to fit into tight spaces, and its wide operating temperature range ensures that it is suitable for a wide range of applications.

Conclusion

The D4BL-2CRA is a highly reliable and robust snap-action, limit switch manufactured by Omron Automation and Safety. It offers a wide variety of uses in both industrial and commercial applications, and its high reliability and resistance to shock, vibration, and corrosion make it suitable for many different applications. Its slim design and wide operating temperature range make it a suitable choice for many different applications.
