Relays with Forcibly Guided Contacts
G7SA
Compact, Slim Relays Conforming to
EN Standards
• 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 50205 Class A, 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.

Note: 1.
The above values are initial values.
2.
Performance characteristics are based on coil temperature of 23°C.
*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.
*6.
When using a P7SA Socket, the dielectric strength between coil contacts/different poles is 2,500 VAC, 50/60 Hz for 1 min. When using Push-
In Plus terminal sockets (P7SA-@F-ND-PU), the dielectric strength between coil contacts as well as between different poles is 4,000 VAC, 50/
60 Hz for 1 min.
*7.
The durability is for an ambient temperature of 15 to 35°C and an ambient humidity of 25% to 75%. For the durability performance to the load,
refer to the Durability Curve.
*8.
AC15: cosφ = 0.3, DC13: L/R = 48-ms.
*9.
The failure rate is based on an operating frequency of 300 operations/min.
*10.
12 to 48 VDC: When operating between 70 and 85°C, reduce the rated carry current of 6 A by 0.1 A for each degree above 70°C.
110 VDC: When operating between 40 and 60°C, reduce the rated carry current of 6 A by 0.27 A for each degree above 40°C.

When operating the P7SA-@F-ND-PU at a temperature between 50 and 70°C, reduce the continuous current (6 A at 50°C or less) by 0.25 A
for each degree above 50°C.
When operating the P7SA-@F-ND at a temperature between 50 and 70°C, reduce the continuous current (6 A at 50°C or less) by 0.3 A for
each degree above 50°C.
When operating the P7SA-@F at a temperature between 50 and 85°C, reduce the continuous current (6 A at 50°C or less) by 0.1 A for each
degree above 50°C.
