Why Choose the Original Model
- Guaranteed compatibility — engineered specifically for OMRON MY2/MK2 relay series with precise pin alignment.
- Certified quality — UL, CE, and RoHS compliant for global deployment in industrial environments.
- Long service life — silver alloy contacts rated for 10A continuous load with minimal contact resistance.
- Ease of maintenance — relay can be replaced without rewiring; screw terminals accept standard wire gauges.
- Proven in field — widely deployed in automotive, food processing, and building automation industries worldwide.
Typical Applications
- PLC I/O expansion and relay output modules
- Industrial control panels and MCC (Motor Control Centers)
- HVAC and building automation systems
- Machine tool and conveyor control circuits
- Power distribution and protection relay circuits
- Process automation in chemical and food industries
System Compatibility
The PYF08A-E is compatible with the following OMRON relay models when used as the mating socket:
- OMRON MY2 / MY2N / MY2N-J (8-pin, DPDT)
- OMRON MK2P / MK2P-I (8-pin, DPDT)
- OMRON LY2 / LY2N (8-pin, high-power)
For 11-pin or 14-pin relay configurations, refer to the PYF11A-E or PYF14A-E models respectively.
Selection Guide
Use the following criteria to confirm the PYF08A-E is the correct socket for your application:
- Pin count: Confirm your relay has 8 pins (DPDT configuration).
- Relay brand/series: Verify relay is OMRON MY2, MK2, or LY2 series.
- Mounting method: PYF08A-E supports both DIN rail clip and direct panel screw mounting.
- Current rating: Ensure load current does not exceed 10A per contact.
- Voltage: Rated for 250V AC / 300V DC — suitable for most industrial control voltages.
- Environment: Rated for -40°C to +70°C; suitable for standard industrial enclosures.
If your relay is a different brand or series, consult the replacement table above or contact our technical team for a cross-reference.

Replacement & Compatibility FAQ
Q: Can I use PYF08A-E with non-OMRON relays?
A: Functionally possible if the relay has an 8-pin octal base with matching pin spacing, but we recommend verifying the datasheet. Contact us for cross-reference support.
Q: What is the difference between PYF08A and PYF08A-E?
A: The “-E” suffix denotes compliance with European safety standards (CE marking). Electrically and mechanically identical.
Q: Is DIN rail clip included?
A: Yes, the PYF08A-E includes a DIN rail mounting clip. Surface mount screws are not included.
Q: Can this socket handle 24V DC relay coils?
A: The socket itself is coil-voltage agnostic — it connects to the relay’s contact pins. Coil voltage is determined by the relay, not the socket.
Q: What wire gauge is compatible with the screw terminals?
A: Accepts AWG 22–14 (0.3–2.5 mm²) stranded or solid wire.
