D4SL-2RDG-D

D4SL-2RDG-D is a type of snap action, limit switch, a device used to sense the position of moving objects, such as in mechanical controls, safety interlocking devices and medical automation systems. It is installed with a plunger or roller lever actuator, which when pushed or pulled by an external object, activates an internal switch. This type of limit switch is distinguished for its quick "snap action", making it ideal for applications where time is a valuable factor, such as in industrial automation.

The D4SL-2RDG-D switch is configured into three contact blocks, each containing a pair of normally open (NO) and normally closed (NC) contacts. This switch is designed to be operated at 10A 250VAC. Its construction is diecast aluminum, with reinforced polyester covers, providing high quality and corrosion resistance. The shape of the device is designed to integrate into other mechanisms, with width of 50.6mm, height of 31.5mm, and depth of 28.5mm. The breaking capacity is 2500VA at maximum, providing reliable, safe and durable switching.

The operating temperature range for this switch should be between -25°C to 70°C, and its operating force between 3N and 7N. These two features, although integral in all snap action limit switches, are extremely important in guaranteeing correct operation and stability of the switch. Additionally, the D4SL-2RDG-D switch offers protection against electromagnetic compatibility, with internal fixed IP67 protection, able to bear temperatures up to +80°C and quick-connect terminals for easy maintenance.

The working principle of the abovementioned snap action limit switch is quite simple. After installation, the plunger (or roller lever actuator) will remain in its inactivated state, in which the internal normally opened contacts remain open due to the absence of an external force. However, when an external force is detected, the plunger will mechanically transmit the force to the internal switch, causing the normally open contacts to close "snapping" over its actuated state. Afterwards, the switch can be reset to its inactivated state, returning its internal switches to the normally open state.

The D4SL-2RDG-D switch, due to its snap action and quick response, can be used in any application that requires fast and precise sensing of position, speed or direction of movement. This includes industrial automation (such as machines, production lines, robotic arms, etc.), transportation, door interlocking, motor control, and other industrial and commercial applications.

In conclusion, the D4SL-2RDG-D snap action limit switch offers quality and reliability in a small package that integrates into any application. Its quick response and versatile contact configuration makes it a perfect choice for many industrial and commercial applications, providing safety and accuracy in any mechanism that requires precise position sensing.
