Introduction

The D4SL-N3RFA-D4 is a Snap Action, Limit Switches. It is an all-in-one single pole double break, floating contact, snap-acting limit switch for AC and DC applications. Designed for ruggedized applications, this switch has a long life cycle of up to 20 million operations, tested at an operating temperature range of -55°C to 80°C.

Application Field

The D4SL-N3RFA-D4 is a durable, contact-based switch that is great for a variety of applications. These applications include automotive, medical, and industrial applications. The contact-based switch is also perfect for robotics and low-voltage AC/DC control circuits. Other applications include remote control and signaling systems, home appliances, heating, ventilation, and air conditioning systems. The contact-based switch can also be used with hoists, lifts, and doors.

Working Principle

The operation of the D4SL-N3RFA-D4 switch is based on a snap-action principle. When the contact is triggered, the contact arm is forced away from the blade and the circuit changes state. Until the contact is reset, the switch remains in the current state. When reset, the contact arm is pushed back against the blade and the circuit is open again. The advantage of this snap-action principle is that the switch is able to respond quickly and accurately to signals in order to perform the desired function. It also has higher long-term stability and reliability, due to its durable structure and operation,

Construction

The D4SL-N3RFA-D4 is constructed with a die-cast aluminium housing. This ensures long-lasting durability for all applications. The switch is then sealed with an IP67 rated gasket, enabling it to withstand water and dust ingress. The silver plated contacts, encapsulated with arc-resistant insulation, are designed to provide high-performance switching and increased life.

Specifications

The main specifications of the D4SL-N3RFA-D4 switch include a voltage rating of 250 VDC/250 VAC, a maximum current of 3A, a maximum carry current of 1A, a maximum contact resistance of 15 milliohms, and an average switching rate of 0.25 ms. The switch also has a contact gap of 0.4 mm, a minimum insulation resistance of 1000 megohm at 500V DC, and a mechanical life of up to 20 million operations.

Conclusion

The D4SL-N3RFA-D4 is a Snap Action, Limit Switches perfect for a range of industrial applications. It is a long-life switch with a stable and reliable operation, sealed with an IP67 gasket for water and dust ingress prevention. With its durable die-cast aluminium housing and high-performance silver-plated contacts, the D4SL-N3RFA-D4 switch is a great choice for many applications.
