MRE-
Series

(formerly known as 802-Series)

Relays with 1- 4 form A or form C switches, HI versions available

These relays in plastic casings can be equipped with 1-4 form A switches (dry or mercury wetted) or 1-4 form C switches. Various switch types with long air and creepage paths between coil and switch can be used. Versions with an extremely high insulation resistance of 10¹⁴ Ohm achieved through a special epoxy potting compound are also available for special requirements of test systems and precision measuring devices.

Typical applications:

• Test, measurement and control equipment
