Snap action, limit switches are electromechanical devices that are designed to control the actions of devices or machines. They are extremely versatile and used in a variety of applications, industrial or domestic. The D2MQ-4L-1 is a popular limit switch made by the Omron Corporation. It is a two-pole, two-throw type that is suitable for automatic or manual operation. It has a wide current rating from 5mA up to a maximum of 5A.

Application Field

D2MQ-4L-1 limit switches are well suited for use in a variety of applications. In industrial settings, they can be used for monitoring and controlling the movement of cranes, conveyor belts, lifts and other mechanisms. In domestic settings they can be used with washing machines, refrigerators, dishwashers, ovens, stoves and other home appliances. They are also used in commercial settings such as offices, banks, shops and other places of business.

Working Principle

The D2MQ-4L-1 limit switch operates using four control signals: one for input and one for output, as well as two open-collector outputs. When the desired position is reached, the switch causes a low-level current to flow through the controlling circuit, allowing the connected device or machine to operate. The limit switch also provides an extra level of protection by cutting off the power supply if the current exceeds the rated level.

In addition to its standard operation, the D2MQ-4L-1 can also be used in a pulse-width-modulated (PWM) mode. In this mode, the control signals are pulsed as long as the desired position has not been reached. This provides a greater degree of accuracy, which is especially useful in applications such as stair lifts or elevators.

The D2MQ-4L-1 limit switch is a robust, reliable and cost-effective solution for controlling a variety of devices and machines. Its wide range of features and versatility make it suitable for both industrial and domestic applications.
