DESCRIPTION
The 134 sensitive Centigrid relay retains the same features as the 114
standard Centigrid relay with only a minimal increase in profile height (.375
in.). Its .100-inch grid spaced terminals, which preclude the need for spreader

packaging density is important.
ARMATURE The following unique construction features and manufacturing techniques
provide excellent resistance to environmental extremes and overall high
reliability:
All welded construction.
Unique uni-frame design providing high magnetic efficiency and mechanical

rigidity.
CONTACT
MOVING
High force/mass ratios for resistance to shock and vibration.
CONTACT
Advanced cleaning techniques provide maximum assurance of internal
cleanliness.
Precious metal alloy contact material with gold plating assures excellent
high current and dry circuit switching capabilities.
The Series 134D and 134DD have internal discrete silicon diodes for coil
suppression and polarity reversal protection.
ENVIRONMENTAL AND
PHYSICAL SPECIFICATIONS
The sensitive 134 Centigrid relay has a high resistance coil, thus requiring
Temperature
extremely low operating power (200 mw typical). The advantages of reduced

(Ambient)
heat dissipation and power supply demands are a plus.
Vibration

features of good RF performance, small size, low coil power dissipation and
high reliability make it a preferred method of Transmit-Receive switching (see
