Reliable DC-Controlled Switching for Industrial Automation
The Finder 62.23.9.110.4040 provides an effective interface between DC control signals and electrical load circuits. When its 110 V DC coil is energised, the relay's electromagnetic mechanism changes the position of its three changeover contacts, enabling connected equipment to be controlled according to the electrical system's requirements.
The three-pole changeover arrangement provides normally open and normally closed switching paths for three separate circuits. This makes the relay particularly useful for auxiliary control, equipment sequencing, signalling and electrical interlocking applications where several circuits must respond to a common control signal. When coil power is removed, the monostable mechanism returns the contacts to their normal positions.
The AgSnO2 silver tin oxide contacts provide a cadmium-free contact material with good resistance to contact erosion and welding under suitable operating conditions. This makes the contact configuration useful for industrial switching duties, although the connected load must remain within the relay's specified electrical ratings. Inductive loads, motors and equipment with high inrush currents may require additional protection or application-specific derating.
The Finder 62 Series also incorporates reinforced insulation between the coil and contacts, supporting electrical separation in industrial control designs. Its PCB-mounted construction enables direct installation into electronic control assemblies, while the established electromagnetic switching mechanism supports predictable operation throughout the equipment's service life.
