• Additional Push-In Plus terminal sockets are used to save wiring work in comparison with traditional screw terminals.
(Wiring time is reduced by 60%* in comparison with traditional screw terminals.)

• Relays with forcibly guided contacts (EN/IEC 61810-3, Certified by VDE).

• Supports the CE marking of machinery (Machinery Directive).

• Helps avoid hazardous machine status when used as part of an interlocking circuit.

• Four-pole and six-pole Relays are available.

• The Relay’s terminal arrangement simplifies PWB pattern design.

• Reinforced insulation between inputs and outputs. Reinforced insulation between some poles of different polarity.

*1. The contact resistance was measured with 1 A at 5 VDC using the voltage-drop method.
*2. These times were measured at the rated voltage and an ambient temperature of 23°C. Contact bounce time is not
included.
*3. The response time is the time it takes for the normally open contacts to open after the coil voltage is turned OFF.
Contact bounce time is included. Measurement conditions: Rated voltage operation, Ambient temperature: 23°C
*4. The insulation resistance was measured with a 500-VDC megohmmeter at the same locations as the dielectric
strength was measured.
*5. Pole 3 refers to terminals 31-32 or 33-34, pole 4 refers to terminals 43-44, pole 5 refers to terminals 53-54, and
pole 6 refers to terminals 63-64.
