DESCRIPTION
The 114 sensitive Centigrid relay retains the same features as the 114
High force/mass ratios for resistance to shock and vibration.
standard Centigrid relay with only a minimal increase in profile height
Precious metal alloy contact material with gold plating assures excellent
(.275 in.). Its .100-inch grid spaced terminals, which preclude the need for
high current and dry circuit switching capabilities.
spreader pads, and its low profile make the 134 relay ideal for applications
where high packaging density is important.
The Series 114D and 114DD have internal discrete silicon diodes for coil
suppression and polarity reversal protection.
The following unique construction features and manufacturing techniques
provide excellent resistance to environmental extremes and overall high
reliability:
By virtue of its inherently low intercontact capacitance and contact circuit
losses, the 114 relay has proven to be an excellent ultraminiature RF
The 114 feature:
switch for frequency ranges well into the UHF spectrum. A typical RF
application for the Centigrid relay is in handheld radio transceivers,
All welded construction.
wherein the combined features of good RF performance, small size, low
Advanced cleaning techniques provide maximum assurance of internal
coil power dissipation and high reliability make it a preferred method of
cleanliness.
Transmit-Receive switching
Unique uni-frame design providing high magnetic efficiency and
mechanical rigidity.
