NOTES:

 

1. The range of coil current is 

 

±

 

15% for AC 

(60 Hz), and 

 

±

 

10% for DC, at 20

 

°

 

C.

2. The relay is applicable to the range of 

80 % to 110% of the nominal coil voltage. 

However, it is recommended that the relay 

be used in the range of 85% to 110% to 

take temporary voltage variations into 

consideration.

3. The coil resistance of DC types is the 

measured value at a coil temperature of 

20

 

°

 

C. Please compensate coil resistance 

by 

 

±

 

0.4% for each degree centigrade coil 

temperature change.

4. All AC 240 V types are rated for double 

coil voltages, both AC 220 V and AC 240 V.

5. For use with 220 V or 240 V DC, con-

nect a resistor as suggested in the chart 

below, in series with the 110 V DC relay.

Amber Relays HCE

HC sealed relays are version of the HC 

relays and are recommended for use in 

switching medium loads under adverse 

ambient conditions. They show highly sta-

ble contact resistance even after long use, 

due to their sealed construction and reli-

able gold plated contacts. Amber relays 

also make the combined process of auto-

matic wave soldering and cleaning pro-

cess possible with their resultant savings

The diagram at right shows a cross-sec-

tion of the plastic sealed relay.  All the 

plastic parts are annealed and out-

gassed to ensure fully the stability of both 

chemical and physical characteristics.

Bifurcated contact types HC4D

Extremely high contact reliability has 

been made possible by adoption of gold-

clad bifurcated contacts for both movable 

and stationary contacts.

HC4D type can be used from the dry cir-

cuit 100 

µ

A at 10 V DC to the power circuit 

3 A at 250 V AC resistive load.

Therefore, with HC4D type such a usage 

is possible that one contact switches 100 

µ

A and another contact switches 3 A load. 

Also Amber sealed types are available as 

HC4ED relays.

Notes:

1. Configuration and dimensions of HC2K 

types are the same as those of standard HC4 

types. Standard sockets and screw terminal 

sockets of HC4 can be used: HC4-SS-K, 

HC4-PS-K, HC4-WS-K, and HC4-HSF-K.

2. Please note that circuit diagram of HC2K is 

different from HC4.

3. Avoid operation by capacitor since latching 

force varies according to input pulse voltage.

LED wired types: HC-L

The built-in indication LED (Light emitting 

diode) Series are suitable for instant indi-

cation of operate function in applications 

where numerous relays are to be used. 

The HC-L relays are supplied with LED 

wired in parallel with the coil for visual in-

dication that the relay is functioning. A 

Red LED is used for AC type and green 

one for DC.
