DESCRIPTION
The Series 114 Centigrid® relay is an ultraminiature, hermetically sealed,
armature relay. Its low profile height (.275") and .100" grid spaced terminals,
which precludes the need for spreader pads, make it ideal for applications
where extreme packaging density and/or close PC board spacing are required.
The basic design and internal construction are similar to the standard
Teledyne DPDT TO-5 relay (e.g., Series 412). The following unique
construction features and manufacturing techniques provide overall high
reliability and excellent resistance to environmental extremes:

• All welded construction.
• Unique uni-frame design providing high magnetic efficiency and mechanical
rigidity.
• High force/mass ratios for resistance to shock and vibration.
• 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 114D and 114DD relays have internal discrete silicon diodes for
coil suppression and polarity reversal protection.
By virtue of its inherently low intercontact capacitance and contact circuit
losses, the 114 relay has proven to be an excellent ultraminiature RF switch
for frequency ranges well into the UHF spectrum. A typical RF application for
the 114 relay is in handheld radio transceivers, wherein the combined features
of good RF performance, small size, low coil power dissipation and high
reliability make it a preferred method of Transmit-Receive
switching (see Figure 1).

Notes:
1. Spreader pad material: Diallyl Phthalate.
2. To specify an “M”, “M2” or “M3” spreader pad, refer to the mounting variants portion of the part number example
in the applicable datasheet.
3. Dimensions are in inches (mm).
4. Unless otherwise speci¿ed, tolerance is ± .010” (0.25).
5/. Add 25 mȍ to the contact resistance shown in the datasheet.
6/. Add .01 oz. (0.25 g) to the weight of the relay assembly shown in the datasheet.
7/. Add 50 mȍ to the contact resistance shown in the datasheet.
8/. Add 0.025 oz (0.71 g) to the weight of the relay assembly shown in the datasheet.
9/. M3 pad to be used only when the relay has a center pin (e.g. ER411M3-12A, 722XM3-26.)
