Engineering Data
■OPERATING RANGE ■DETECTING DISTANCE
VS. SIZE OF TARGET ■DETECTING DISTANCE
VS. MATERIAL OF
TARGET
Material Detecting distances
Mild steel 15 mm (0.59 in)
Stainless steel 10 mm (0.39 in)
Brass 6.4 mm (0.25 in)
Aluminum 5 mm (0.20 in)
Copper 5 mm (0.20 in)
Note: Standard target size is 30 x 30 x
1 mm.
Note: If the target is a nonferrous metal, the oper ating distance of the proximity sensor decreases. Ho wever , with a piece of f oil measuring
about 0.01 mm (0.0004 in) in thickness, the detecting distance is equivalent to that with a ferrous metal. Note that the proximity
sensor cannot detect extremely thin evaporated films and non-conductive targets.

110 VAC 220 VAC Note: When the current rating of the
load is less than 10 mA, false
operation may occur. This is
normal, and the problem can be
solved by installing a bleeder
resistor in parallel with the load.
Use the formulas given here to
calculate the power rating and
value of the resistor.
R < Vs (kΩ) P > Vs2 (mW)
= 10 – i R
P : Wattage of bleeder resistor
i :Load current (mA)

■LEAKAGE CURRENT CHARACTERISTICS
AC Switching Types
TL-YS15MY

-US
Note: Even when the proximity sensor is in the OFF state, a
very small amount of current flows to operate the internal
circuit of the sensor. Because of this leakage current, a
small voltage is generated in the load, which may
occasionally result in improper resetting of the load.
Before using the proximity sensor, confirm that this
voltage is less than the release voltage value of the load.

Precautions
■EFFECTS OF SURROUNDING METALS
When mounting a proximity sensor flush with a metallic panel,
be sure to provide a minimum distance as shown in the table
to prevent the sensor from being effected by metallic objects
other than the target.
■MUTUAL INTERFERENCE
To prevent mutual interference, be sure to space the sensors
at a distance greater than that shown in the table below.

A 45 (1.77)
B 45 (1.77)
Drawing dimension Minimum distance

C 150 (5.91)
D 200 (7.87)
■INFLUENCE OF PLATING
Metals with different types of plating effect the detecting
distance of inductive proximity sensors. The table at r ight
shows reference values for the percentage of the rated
detecting distance that may be expected by type of plating
materials.
