D4N-4C72R

D4N-4C72R snap action limit switches are widely used in various applications due to their reliable performance. The switch is rated for a maximum operating temperature of -40C to +85C, and it operates in environments ranging from low-voltage to hazardous locations. It features a snap-action contact mechanism and is used to detect mechanical motion or position changes. The switch has two types of mechanisms – One is a micro-switch type, which provides sensitive motion or position sensing. The other is a paddle lever type, which provides a more robust and reliable motion or position sensing.

The D4N-4C72R is designed to sense contacts mechanically rather than electrically, making it resistant to electrical interference, temperature drift, and vibration. The switch has a built-in actuator that senses when a limit is reached and engages a contact to break/make an electrical connection. This mechanism makes it useful in a variety of applications, such as overspeed protection, cycle time monitoring, and positional sensing.

It has four poles, each terminal of which can be connected to a separate circuit. The switch also has various ranges, including SPDT/SPST versions and NOR/NC versions, which makes it suitable for a variety of applications. One of its main advantages is that it has a low actuation force, meaning it can be triggered with only a minimal movement or force. It also has a wide operating temperature range, making it ideal for use in harsh environments.

The D4N-4C72R operates by sensing three-dimensional mechanical motion or position change. When the switch actuator is pulled or released, it is engaged with the contact plate such that it is pushed into the contact plate, creating an electrical connection and breaking an electrical connection as required. The switch also has a double-break contact arrangement, which ensures a reliable break between the two contacts.

The D4N-4C72R is highly reliable and its performance is robust in the face of the most challenging conditions. Its small size and compact design combined with its reliable performance make it the ideal choice for a variety of applications, from industrial settings to hazardous locations. Its various range of switching mechanisms and low actuation force make it suitable for even the most sensitive applications, making it the best choice for any application requiring a reliable snap-action limit switch.
