Note: Terminals (Nos. 12 and 9) are pulled from the respective

diode and reset coil. Use these terminals through external

connection for selective use or non-use of the diodes as

well as for surge prevention.

G2AK

Safety Precautions

Refer to Safety Precautions for All Relays.

The G2AK can be used for special purposes by utilizing its built-in diodes.

When built-in diodes are not required

• With the DC-coil Latching Relay, the built-in diodes become

unnecessary for a circuit in which a coil operating switch is

incorporated for each of the set and reset coils as shown on the

right.

* Unwanted diodes

•

With the DC/AC-coil Latching Relay, if the junctions between the

set coil and built-in diode and between the reset coil and built-in

diode are connected as shown on the right, only one of the

built-in diode is required and the rest of the diodes become

unnecessary. However, a coil operating switch is required for

each coil. In this case, because of the diode characteristics, the

load rating must be 0.5 A or less.

Unwanted diodes

When built-in diodes are required

• When using the AC-coil Latching Relay which operates on

commercial AC input, the built-in diodes are required.

• With the DC/AC-coil Latching Relay, the built-in diodes are

required for an inductive electrical equipment circuit which

consists of two or more set/reset coils, motor M, general

electromagnetic coil X, etc. per coil operating switch as shown

on the right.

Set or reset coil

Examples of built-in diode applied circuit

• With the DC-coil Latching Relay, the built-in diode(s) can be

used for surge absorption. in this case, pay attention to the

polarity of the coil. Note that the 5-minute rating applies only to

the set coil rated at 6 VDC and the continuous rating for other

DC coil voltages remains unchanged.

The figures above represent the terminal num-

bers. The figures in parentheses represent the

terminals on the set side.

• With the AC-coil Latching Relay, a half-wave rectified power

supply can be obtained as shown on the right. This can be

used as a power supply for light-emitting diodes. However,

because of the diode characteristics, the load rating must be

0.5 A or less.

Set or reset coil

See note below.

Note: If a smoothing capacitor is used as shown on the right, the

waveform of the current that flows into the set or reset coil

changes from half wave to that of nearly direct current. In

other words, ripple is improved but the coil temperature

rises, which may adversely affect the set or reset voltage.

Therefore, avoid circuit configuration with an electronic

device which improves ripple, such as a capacitor.

Circuits

Do not allow voltage to be applied simultaneously to both the

set and reset coil. If voltage is applied simultaneously, the

operation will become unstable.
