Coil Ratings
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for rated currents and
±15% for DC coil resistance.
2. Performance characteristic data are measured at a coil temperature of 23°C.
3. AC coil resistance and impedance are provided as reference values (at 60 Hz).
4. Power consumption drop was measured for the above data. When driving transistors, check leakage current and connect a bleeder re-
sistor if required.
5. Rated voltage denoted by “*” will be manufactured upon request. Ask your OMRON representative.

Note: 1. The values given above are initial values.
2. The values for insulation resistance were measured at 500 V at the same place as the dielectric strength.
3. The maximum operating ambient temperature for the PYF08A-N and PYF14A-N is 55°C.
4. When using the PYF08A-N or PYF14A-N at an operating ambient temperature exceeding 40°C, reduce the current to 60%.
5. The MY2(S) can be used at 70°C with a carry current of 7 A.

PYF-S Installation Notes
Tools
A flat-blade screwdriver should be used to mount the cables.
Applicable Screwdriver
Flat-blade, Parallel-tip, 2.5 mm diameter (3.0 mm max.)
Examples: FACOM AEF.2.5 × 75E (AEF. 3 × 75E)
VESSEL No. 9900-(-)2.5 × 75 (No. 9900-(-)3 × 100)
WAGO 210-119
WIHA 260/2.5 × 40 (260/3 × 50)
*Chamfering the tip of the driver improves insertion when used as an exclusive tool.
Applicable Wires
Applicable Wire Sizes
0.2 to 1.5 mm2, AWG24 to AWG16
Applicable Wire Type
Solid wires, stranded wires, flexible wires, or wires with ferules can
be used.
(See note 1.) < 2.2 Diameter D (mm) 3.2 (3.5: see note 2.)
Conductor diameter d (mm) or length of sides a and b (mm) 1.9
Note: 1. If the overall diameter of the wire is less than 2.2 mm, do not
insert the wire past the conductor. Refer to the following di-
agrams.
2. If the overall diameter of the wire is over 3.2 mm, it will be
difficult to use double wiring.

Examples of Applicable Wires (Confirmed Using Catalog Information)
Wiring
Use wires of the applicable sizes specified above. The length of the
exposed conductor should be 8 to 9 mm.
Use the following wiring procedure.
1. Insert the specified screwdriver into the release hole located
beside the wire connection hole where the wire is to be inserted.
2. Insert the exposed conductor into the wire connection hole.
3. Pull out the screwdriver.
Note: Use no more than 2 wires per terminal, 1 wire per hole.

Precautions
Precautions for Connection
Do not move the screwdriver up, down, or from side to side while it
is inserted in the hole. Doing so may cause damage to internal
components (e.g., deformation of the coil spring or cracks in the
housing) or cause deterioration of insulation.
Do not insert the screwdriver at an angle. Doing so may break the
side of socket and result in a short-circuit.
Do not insert two or more wires in the hole. Wires may come in con-
tact with the spring causing a temperature rise or be subject to
sparks. (There are two wiring holes for each terminal.)
Insert the screwdriver along the hole wall as shown below.
If lubricating liquid, such as oil, is present on the tip of screwdriver,
the screwdriver may fall out resulting in injury to the operator.
Insert the screwdriver into the bottom of the hole. It may not be pos-
sible to connect cables properly if the screwdriver is inserted incor-
rectly.
General Precautions
Use the clip to prevent relays floating or falling out of the socket.
Do not use the product if it has been dropped on the ground. Drop-
ping the product may adversely affect performance.
Confirm that the socket is securely attached to the mounting track
before wiring. If the socket is mounted insecurely it may fall and
injure the operator.
Ensure that the socket is not charged during wiring and mainte-
nance. Not doing so may result in electric shock.
Do not pour water or cleansing agents on the product. Doing so
may result in electric shock.
Do not use the socket in locations subject to solvents or alkaline
chemicals.
Do not use the socket in locations subject to ultraviolet light (e.g.,
direct sunlight). Doing so may result in markings fading, rust, corro-
sion, or resin deterioration.
Do not dispose of the product in fire.
Removing from Mounting Rail
To remove the socket from the mounting rail, insert the tip of screw-
driver in the fixture rail, and move it in the direction shown below.
