Features
Transmit Multiple Switch Signals and Power
to without Contact
By connecting the B7AP Power Coupler between the B7A
Input Unit and B7A Output Unit, it is possible to transmit
multiple switch signals without contact from input devices to
controllers. When using the B7AP Power Coupler in this way,
it is possible to transmit power via electromagnetic coupling,
so a power supply for the Input Unit is not necessary.
Equipped with a Verification LED for Easy
Settings
The B7AP-M1 is equipped with an operation indicator that
lights the usable range during Coupler setup, allowing for
easy setup.
Total Transmission Distance Up to 100 m
The transmission distance between Power Couplers without
contact is 8±1.5 mm. The maximum transmission distance
between the B7A Input Unit and B7A Output Unit is 100 m
(when transmitting power or signals).
Transmission Also Possible When
Separated by a Non-metallic Object
Switch signals and power can be transmitted even when there
is plastic, glass, wooden, or other non-metallic objects
between the Couplers (B7AP-S1/-M1).

Usable in a Variety of Environments with
IP67 Environmental Resistance
The Couplers have IP67 degree of protection, which allows
them to be used in harsh environments that may expose them
to dust from glass, plastic or paper, or exposure to water. The
Couplers can be used in a wide range of applications.
Select Transmission Method Based on
Application Conditions
When transmitting power and transmission signals, a
maximum of 10 points can be input simultaneously to the B7A
Input Unit.
(B7A Input Unit: Input Current 3.8 mA × 10 points = 38 mA)
When transmitting only signals, a maximum of 16 points can
be input to the B7A Input Unit.
Applications

*1. The maximum I/O points refers to the maximum I/O points handled simultaneously by the B7A Input and Output Units. Figures in
parentheses indicate the maximum I/O points handled simultaneously by the B7A Input and Output Units each connected with an
independent power supply. Refer to the Power Supplies page.
The B7AH requires two types of power supplies (24 VDC and 5 VDC), so a power supply is required for each Unit.
*2. The maximum I/O points are the same as the maximum input points of the B7A Input Unit connected to the B7AP-M1.
*3. PLCs and three-wire sensors can be connected only if the B7A Input and Output Units are each connected with independent power
supplies. Refer to the section on Power Supplies.

Safety Precautions
This product is not designed or rated for
ensuring safety of persons.
Do not use it for such purposes.
Be careful when touching the B7AP-S1 (Stationary Unit)
Power Coupler during operation because the surface
temperature of the B7AP-S1 Power Coupler will rise
approximately 20°C after the B7AP-S1 Power Coupler starts
power transmission. The surface temperature varies with the
load of the sensing device connected to the B7AP-M1
(Moving Unit) Power Coupler and the transmission distance.
Do not use this product under ambient conditions that exceed
the ratings.
Handling
1. Use the B7AP-S1 and B7AP-M1 Power Couplers with the
available B7A Link Terminals shown in Connectable B7A
Models on page 3.
The M7E-12@@ Display Unit, M7E-20@@ Display Unit,
B7A-T10M2, B7AC-T10A1, and 16-point High-speed
model cannot be connected to the Power Controller.
2. Use the LOAD-OFF model for the B7A Output Unit to be
connected to the B7AP-S1 Stationary Unit. The LOAD-OFF
model turns OFF all outputs when there is no transmission
between the B7AP Power Couplers.
3. The B7AP Power Couplers must be separated by at least
30 mm to prevent transmission.
4. Do not supply power to the B7AP-S1 or B7AP-M1 Power
Coupler while connecting the Power Couplers to the B7A
Link Terminals. Connect the Power Couplers to the B7A
Link Terminals correctly, otherwise the internal circuits of
the Power Couplers may be damaged.
5. The SIG terminal must not contact with the power supply
terminals, otherwise the internal element may be damaged
and normal transmission may not be possible.
6. Wire the cables of the B7AP-S1and B7AP-M1 Power
Couplers through independent metal conduits to prevent
the Power Couplers from being influenced by noise if there
are power or high-tension lines nearby. Test the Power
Couplers and make sure that the Power Couplers operate
normally before they are put in actual operation.
7. Do not subject the head of the B7AP-S1 or B7AP-M1
Power Coupler to excessive shock with hard objects.
8. Do not use the B7AP-S1 or B7AP-M1 Power Coupler
outdoors unless it is properly protected.
9. Degree of Protection
The B7AP-S1 and B7AP-M1 Power Couplers are products
meeting the requirements of IP67. (They are not fully
sealed water-tight models.) The B7AP-S1 or B7AP-M1
Power Coupler cannot be, however, used in water or oil.
10. Keep the heads of the B7AP-S1 and B7AP-M1 Power
Couplers free from dust, otherwise improper signal or
power transmission may result between the Power
Couplers.
11. When complying with UL standards, install a device
between the external power supply and the B7AP-S1 that
limits the current to 5 A.
Mounting
Use nuts and serrated toothed washers and tighten the nuts.
The torque is 39 N·m maximum. The mounting position will
change and improper signal or power transmission may result
between the Power Couplers if the nuts are not tightened
properly.

Transmission Distance for Stable Signal and Power
Transmission
Use the gauge to adjust the transmission distance to 8 mm,
make sure that the green operation indicator of the B7AP-M1
Power Coupler is lit, and the B7A Output Unit has no error
output before operating the Power Couplers.
Monitoring Transmission Status
Judge from the power supply/error indicator and error output
of the B7A Output Unit whether the B7AP-S1 and B7AP-M1
Power Couplers are facing each other properly. (Use the B7A
Output Unit power and error indicator, and error terminal.)
The error output of the B7A Output Unit will be ON when the
B7AP-S1 and B7AP-M1 Power Couplers are not facing each
other properly.
Minimum Distance between Power Couplers Mounted in
Parallel
When mounting the B7AP-S1 and B7AP-M1 Power Couplers
in parallel, refer to the following table. Keep at least the
specified minimum distance between adjacent Power
Couplers for proper heat radiation by considering the
temperature rise (approximately 20°C) of the B7AP-S1 Power
Couplers in operation.
(Unit: mm)
Effects of Surrounding Metal
The B7AP Power Coupler may malfunction when affected by
surrounding metal. When mounting the B7AP within a metal
panel, ensure that the clearances given in the following table
are maintained. Be sure to check in advance that the B7AP
operates properly.
(Unit: mm)
Maintenance
As with other control devices, regularly check the following to
ensure the long-term stable operation of the B7AP-S1 and
B7AP-M1 Power Couplers.
1. The mounting positions, misalignment, tightening of the
mounting nuts, and warping.
2. The tightening, contacts, and breaking of the lead wires.
3. Dust accumulation on the heads.
4. The ambient operating temperature and other operating
conditions.
5. The transmission distance.
