DESIGNATION

RELAY TYPE

DPDT general-purpose magnetic-latching relay with internal power

MOSFET driver and diode coil transient suppression

122C

The Series 122C relay has internal silicon diodes for coil

suppression, Zener diodes to protect the MOSFET gate inputs, and

N-channel enhancement-mode MOSFET chips, which enable direct

relay interfacing with most microprocessor and IC logic families

(CMOS, TTL and MOS).

DESCRIPTION

The 122C Centigrid^®magnetic-latching relay is an ultraminiature,

hermetically sealed, armature relay capable of being directly driven

by most IC logic families. Its low profile height 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 122C magnetic-latching relay is ideally suited for applications

where coil operating power must be minimized. The relays can be

operated with a short-duration pulse. After the contacts have

transferred, no external coil power is required.

The basic operating function and internal structure are similar to

Teledyne’s TO-5, 422 relay series. The 122C is capable of meeting

Teledyne Relays’ T²R^®requirements. The following unique

construction features and manufacturing techniques provide overall

high reliability and excellent resistance to environmental extremes:

The magnetic-latching feature of the Series 122C relay provides a

“memory” capability, since the relays will not reset upon removal of

coil power.

• All welded construction.

• Unique uni-frame design providing high magnetic efficiency and

mechanical rigidity.

• High force/mass ratios to withstand 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.

By virtue of its inherently low intercontact capacitance and contact

circuit losses, the 122C relay has proven to be an excellent

ultraminiature RF switch for frequency ranges well into the UHF

spectrum. A typical RF application for this Centigrid^®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).

PRINCIPLE OF OPERATION

MAGNETIC CIRCUIT B

Energizing Coil B produces a magnetic field

opposing the holding flux of the permanent

magnet in Circuit B. As this net holding force

decreases, the attractive force in the air gap of

Circuit A, which also results from the flux of the

permanent magnet, becomes great enough to

armature then remains in this position upon removal of energy from Coil B, but will snap

back to position B upon energizing Coil A. Since operation depends upon cancellation

of a magnetic field, it is necessary to apply the correct polarity to the relay coils as

indicated on the relay schematic. When latching relays are installed in equipment, the

latch and reset coils should not be pulsed simultaneously. Coils should not be pulsed

with less than rated coil voltage and the pulse width should be a minimum of three times

the specified operate time of the relay. If these conditions are not followed, it is possible

for the relay to be in the magnetically neutral position.
