Power Relays, Over 2 Amps

1904002-1 is a power relay designed and manufactured by Panasonic, primarily intended for use in industrial applications. It can carry up to 2 Amps of current and is rated for up to 3 Amps of maximum inrush current. The relay is suitable for applications with up to 200 Volts of AC and/or DC power.

Application Field

The 1904002-1 is suited for a wide range of applications, from industrial automation to the motor control of various machines. It is particularly well suited for motor starters, motor drives, frequency inverters, and servo systems, due to its capability to switch on and off large current loads. Additionally, its small size makes it well-suited for tight installations, while its mechanical ruggedness and good insulation properties make it reliable for harsh environments.

Working Principle

The 1904002-1 is a single-pole, single-throw (SPST) power relay. It operates using an electromagnet, activated by applying an external voltage, which pulls up the normally-open contacts of the relay. When the external voltage is removed, the electromagnet is turned off, and the contacts are returned to their original position. This allows the relay to be used to switch on and off large current loads with a high degree of reliability.

The 1904002-1 also features gold-plated contacts, which provide excellent electrical and mechanical reliability. This feature also prevents corrosion and arcing of the contacts, significantly increasing the lifetime of the relay. Furthermore, the relay is designed to operate at temperatures of up to 125°C, which allows for its use in harsh environments without worrying about temperature changes.

The 1904002-1 is designed to be extremely durable and reliable for a wide range of industrial applications. Its small size and wide operating voltage range make it well-suited for tight installations, while its gold-plated contacts and high temperature rating make it reliable for harsh environments. Additionally, its capability to switch on and off large current loads with a high degree of reliability make it ideally suited for motor starters, motor drives, frequency inverters, and servo systems.
