FULL SIZE CRYSTAL CAN RELAY

SENSITIVE 25 and 40 MILLIWATT

Product Description

Series

This ultra sensitive full size crystal can relay series, offers switching capability of low level signals up to 2 amperes under the most

extreme environmental conditions. It is low coil sensitivity and high contact current carrying capacity makes these relays ideal for a

variety of applications. In a unique design, motor efficiency and the proven contact structure of qualified relays, offer sensitivities from

25 milliwatts with low level switching to 2 amperes, low profile, proven designs and wide selection of coil values to provide the designer

with a consistent high quality product for today’s and tomorrow design.

The following construction features ensure the highest reliability in extreme environments:

All welded relay construction

Cleaning and sealing techniques ensures maximum internal cleanliness

Low level to 2 amperes switching

1 or 2 form C, SPDT or DPDT contacts, special metal alloy with gold plating
