SLIM POLARIZED RELAY

FEATURES

1. 2 Form C Slim type

14.0(L) × 9.0(W) × 5.0(H) .551(L) ×

.354(W) × .197(H)

Small header area makes higher density mounting possible

2. Nominal operating power: High sensitivity of 140mW (Single side stable type)

By using the highly efﬁcient polar magnetic circuit “seesaw balance mechanism”, a nominal operating power of 140 mW (minimum operating power of 79 mW) has been achieved.

3. Surge breakdown voltage: 1500 V FCC Part 68

4. Outstanding vibration and shock resistance.

Functional shock resistance: 490 m/s Destructive shock resistance: 980 m/s Functional vibration resistance: 10 to 55 Hz (at double amplitude of 3 mm .118 inch) Destructive vibration resistance: 10 to 55 Hz (at double amplitude of 5 mm .197 inch)

5. High density mounting possible

High-efﬁciency magnetic circuits ensure low magnetic ﬂux leakage. Because characteristics are little changed by proximity mounting, highdensity mounting is possible.

TN RELAYS

6. The use of gold-clad twin crossbar contacts ensures high contact reliability. *We also offer a range of products with AgPd contacts suitable for use in low level load analog circuits (Max. 10V DC 10 mA). *SX relays designed for low level loads are also available.

7. Low thermal electromotive force

As well as low power consumption of 140 mW, use of a structure with separate coil and contact sections has reduced thermal electromotive force to the low level of approximately 5 µV.

8. Latching types also available

9. Self-clinching terminal also

available

10. Sealed construction allows automatic washing.

NOTES

1. Coil operating power

Pure DC current should be applied to the coil. The wave form should be rectangular. If it includes ripple, the ripple factor should be less than 5%. However, check it with the actual circuit since the characteristics may be slightly different. The nominal operating voltage should be applied to the coil for more than 10 ms to set/reset the latching type relay.

2. Coil connection

When connecting coils, refer to the wiring diagram to prevent mis-operation or malfunction.

3. External magnetic ﬁeld

Since T series relays are highly sensitive polarized relays, their characteristics will be affected by a strong external magnetic ﬁeld. Avoid using the relay under that condition.

4. Packing style

The relay is packed in a tube with the relay orientation mark on the left side, as shown in the ﬁgure below.

5. Automatic insertion

To maintain the internal function of the relay, the chucking pressure should not exceed the values below. Chucking pressure in the direction A:

9.8 N {1 kgf} or less Chucking pressure in the direction B:

9.8 N {1 kgf} or less Chucking pressure in the direction C:

4.9 N {500gf} or less

Please chuck the portion. Avoid chucking the center of the relay. In addition, excessive chucking pressure to the pinpoint of the relay should be avoided.

6. Soldering

Preheat according to the following conditions.

Temperature 120°C 248°F or less

Time Within 120 sec

Soldering should be done at 260±5°C
