CS8-2-04

The Norgren CS8-2-04 120 AC Magnetic Reed Switch is an essential component for various automation applications that require magnetic sensing. This switch is designed to provide reliable and accurate detection of magnetic fields, making it an ideal choice for use in industrial automation, HVAC systems, and various other applications.

The CS8-2-04 model is a 120V AC version of the magnetic reed switch series from Norgren. It features two normally open contacts that activate when a magnetic field is present within a proximity of 12mm. The switch is capable of handling up to 1 Amp of current and can operate at temperatures ranging from -25 degrees Celsius to 60 degrees Celsius.

The magnetic reed switch comes with a mounting bracket, which simplifies the installation process. The bracket is made from a durable material and is designed to provide a stable mounting platform for the switch. The switch housing is made from a non-conductive material that ensures insulation and protects the internal components from damage.

The Norgren CS8-2-04 120 AC Magnetic Reed Switch is designed with a robust construction to ensure long-lasting performance. It features a sealing gasket that protects the switch from moisture and other environmental hazards, making it suitable for use in harsh environments. The switch also features a built-in LED indicator, which illuminates when the contacts are closed, making it easy to identify the switch's status.

The switch's operation is straightforward. When a magnetic field is present, the two reed contacts inside the switch are attracted to each other, closing the contacts and completing the circuit. When the magnetic field is removed, the contacts return to their original position, opening the circuit. This mechanism makes the switch ideal for use in applications where detecting the presence or absence of magnetic fields is critical.

In summary, the Norgren CS8-2-04 120 AC Magnetic Reed Switch is a versatile and reliable component for various industrial automation applications. Its robust construction, durable mounting bracket, and accurate magnetic sensing make it an essential tool for ensuring efficient and effective system operation. The switch's easy-to-use design and built-in LED indicator simplify the installation and monitoring process, making it a popular choice among engineers and system integrators.
