The D4B-7170N Limit Switch is a heavy-duty switch designed for use in many applications in demanding environments. The switch is constructed of a metal housing and durable components designed to provide long lasting use and protection from heat, dust, moisture, and vibration. The switch is designed for a variety of industrial applications, including automation and monitoring, material handling, and robotic control.

The D4B-7170N is designed to provide a reliable solution for applications requiring manual operation of limit switches. The switch has incorporated a stepped cam design and adjustable snap action mechanism for precise control of actuation speed and timing of the switch. This allows for precise settings to ensure precise operation with precise speed, repeatability, and accuracy.

The switch can be mounted with an up to 0 - 7.2 mm (0.28" - 0.30") clearance behind the switch and consists of a housing which is sealed to IP67. It also features three conductor terminals (NPN, PNP, and NC) providing an indication to the user when the switch is actuated. The switch can also be pole mounted with a T-handle or with a large adjustable tremble assembly.

The working principle of the D4B-7170N comes from the design of its cam which uses a moveable arm to selectively limit the points in the switch’s stroke where actuation or de-actuation occurs. System settings on the switch can be adjusted to alter the speed, timing, and point of actuation. The actuation point is determined by the stroke of the switch. The switch is set up to actuate when the arm is moved to a certain point in its stroke and then de-actuate when the arm is moved to another point in its stroke. This allows the switch to be used in wide array of applications.

The D4B-7170N\'s adjustable snap action mechanism makes it a dependable solution for many industrial applications in a number of challenging environments. The switch is designed for a variety of applications such as automation and monitoring, material handling, and robotic control. Its adjustable snap action mechanism provides precise operation and long lasting use, ensuring users can count on it in any environment.
