Signal Relays ( 2 A or less ) TQ RELAYS

■ For cautions for use, please read " GUIDELINES FOR SIGNAL RELAYS USAGE " and " GUIDELINES FOR

RELAY USAGE ".

■ Cautions for usage of TQ relay

● Latching

• Use latching when conditions involve continuous

carrying current.

• Regarding the set and reset pulse time, for the purpose

of reliable operation under ambient temperature

fluctuations and different operating conditions, we

recommend setting the coil applied set and reset pulse

time to 10 ms or more at the rated coil voltage.

• The relay is shipped in the reset position. But jolts

during transport or impacts during installation can

change the reset position. It is, therefore, advisable to

build a circuit in which the relay can be initialized ( set

and reset ) just after turning on the power.

● External magnetic field

Since TQ relays are highly sensitive polarized relays,

their characteristics will be affected by a strong external

magnetic field. Avoid using the relay under that condition.

● Precautions for usage of automatic insertion machine

Set the chucking pressure of the pick-up mechanism

by the automatic mounting machine with the pressure

shown in table 1 to maintain the internal function of the

relay.

Please chuck the   portion.

Avoid chucking the center of the

relay. In addition, excessive

chucking pressure to the pinpoint of

the relay should be also avoided.
