• Built-in LED indication type available

Built-in LED eliminates need for design

and mounting of separate LED circuit.

This cuts costs and saves labor.

• Fast response time is achieved

(8 ms or less)

Circuit is quickly opened to ensure

safety.

• High shock resistance

(Functional: Min. 200m/s

)

Improved anti-shock properties

meaning that the relay can be safely

used in high shock and vibration

environments such as in machine tools

and other factory equipment.

• PC board sockets also available

(4 and 6-poles)

• Lineup also includes DIN terminal

socket with finger protect construction

(4 and 6-poles)

TYPICAL

APPLICATIONS

• Machine tools

• Robots

• Safety PLCs

• Circuits with stringent safety standard

requirements such as those in motor

vehicle production equipment.

SFS 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. 2. Coil connection When connecting coils, refer to the wiring diagram to prevent misoperation or malfunction. 3. Cleaning This relay is not sealed, therefore, immersion may cause failure.
