Why Choose the Lovato HR402CD012 Miniature Relay?

The Lovato HR402CD012 is a compact general-purpose miniature relay designed for reliable switching and interface duties in industrial automation, machinery and electrical control systems. Part of the Lovato HR402C miniature relay series, it combines a 12 V DC coil with two changeover contacts, providing flexible control of multiple circuits from a low-power control signal.

The HR402CD012 provides 2 C/O contacts with a rated current and IEC conventional free-air thermal current of 10 A. Its AgSnO2 contact material supports dependable switching performance, while a maximum instantaneous current of 26 A and AC-1 controllable power up to 2500 W make it suitable for a broad range of control loads.

Designed for fitting to compatible Lovato HR5XS2 series sockets, the relay can be integrated into DIN rail control assemblies for straightforward installation and replacement. A mechanical life of up to 10,000,000 cycles, fast operating times and a wide -40 to +85 °C operating temperature range make the HR402CD012 a versatile choice for demanding control-panel applications.

Reliable Interface Switching for Industrial Automation

Miniature relays such as the Lovato HR402CD012 allow a low-power control circuit to switch separate electrical loads while providing galvanic isolation between the control and switched circuits. Its 2 C/O contacts provide flexible normally open and normally closed switching functions, making the relay useful for interlocking, signalling, sequencing and general automation duties.

With a 12 V DC coil, 10 A rated contacts and compatibility with Lovato HR5XS2 series sockets, the HR402CD012 integrates easily into professional control-panel assemblies. Its high mechanical endurance and broad operating temperature range make it suitable for machinery, solenoid valves, contactor interfaces, lighting circuits and other industrial control loads.

Typical Applications

  • Industrial automation and control panels.
  • Machinery control and interlocking circuits.
  • Contactor and solenoid valve interfaces.
  • Lighting and auxiliary load switching.
  • PLC output isolation and interface circuits.
  • OEM machinery and electrical equipment.
