Snap Action, Limit Switches, have a wide application field due to their easy operation, durable design and great variety of types. The D4NH-6FBC is one of these switches, which have comes in many sizes and shapes, and offer various options for reliable operation of various mechanical applications. To simplify the mode of operation and control, the D4NH-6FBC utilizes a rugged construction, consisting of a stationary magnet encased in a hermetically sealed plastic case. When the load is applied, the magnet is drawn towards the electromagnet, drawing the plunger in between them and allowing the switch to be operated. The working principle of the switch is very simple. When the load is applied, the switching of the contacts is triggered by a mechanical device. When the contacts are opened and closed, the electrical current is interrupted, and the operating mechanism of the switch is completed.The switch is designed to be operated in two stages: contact triggering and contact opening/closing. When the snap action is initiated, the magnets inside the switch attract the plunger, which pulls the contacts closer to complete the switching cycle. The contact triggering is achieved by applying a set force to the plunger by an operator, and the contact opening/closing is accomplished by the plunger being released and bounced back to its original position. The switch is designed for a wide range of temperature conditions, and it can withstand a wide temperature range from -25°C to 75°C and up to 125°C for some models. The D4NH-6FBC is available in several versions and models, ranging from single pole to latching models, meaning that it can be used in applications where the switch needs to be activated with the same or different action, or needs to be latched with the same or different action. The switch is available in several mounting styles, such as flush, surface, panel and through hole mounting, which can be chosen in order to optimize the installation in a wide range of applications. These switches are often used in machines, manufacturing, automotive and medical operating equipment, which makes it a very versatile device.For further usage versatility, the D4NH-6FBC has a few options when it comes to the type of contact. The contact can be set to normally open (NO), normally closed (NC) and dual-circuit normally open/closed (NC/NO). This means that the user can create different combinations of contact action, depending on their needs.The D4NH-6FBC is rated for a maximum current of 4A 250VAC, a rated operating frequency of 20kHz, a maximum operating pressure of 17pounds and a maximum electrical travel of 1.5mm. With a gold plated contact, this switch is capable of delivering reliable performance for up to 5 million cycles. In conclusion, the D4NH-6FBC is a versatile and reliable snap action, limit switch offering great versatility when it comes to different applications. With its rugged construction, reliable operation, wide temperature range, multiple contact options and gold plated contacts, it is well suited for a variety of machines, manufacturing, automotive and medical operating equipment.
