Reliable 110 V DC Control with Wide-Gap Power Contacts
The Finder 66.82.9.110.1601 operates through an electromagnetic coil controlled by a 110 V DC supply. When the coil is energised, the relay closes its two normally open contacts, allowing current to flow through the connected electrical circuits. Removing the coil supply returns the contacts to their open positions, interrupting the controlled loads.
The relay's wide contact-gap construction offers increased physical separation between open contacts compared with conventional contact-gap arrangements. Combined with flange mounting, Faston terminals and reinforced coil-to-contact insulation, this makes the Series 66 relay suitable for integration into industrial electrical systems. Contact ratings, DC breaking capacity, load characteristics and protective devices must be assessed for the intended switching duty.
Typical Applications
- Industrial automation and electrical control systems.
- Industrial machinery and equipment switching circuits.
- Electrical control panels using 110 V DC control supplies.
- Power management and auxiliary switching systems.
- Heating, ventilation and air conditioning (HVAC) equipment.
- Electrical heating and temperature control systems.
- Commercial and industrial appliance controls.
- Industrial process control equipment.
- OEM machinery requiring flange-mounted power relays.
