TS-L, -M, -H Series
Sensors
Mechanical Sensors
Powder Level Sensors
Plain paper copiers and laser printers require the toner (pigment
powder) and carrier (magnetic powder) to be mixed in the proper
proportions to create the developer. TDK’s TS series of toner sen-
sors was designed to maintain this correct mix ratio.
FEATURES
• The TS-L, TS-M and TS-H toner sensors use
a high
performance ferrite core differential transformer with an
adjustable control lead wires. When the DC voltage applied to
the control lead wires is varied, the sensor working point also
varies. Since the control lead wires (and working point) can be
set to practically any desired value, it provides the following
capabilities:

• Because it has such a wide control range, the working point can
be reset easily after changing the developer, or whenever
needed.

• The microprocessor in the printer or copier can vary the control
lead voltage for automatic adjustment.
L: TH core(Standard)
M: TH+RI core(Shielded)
• In multi-color printers, it is no longer necessary to use a different
constant sensor for each color. One TDK programmable toner
sensor can accommodate the working point differences of each
color toner with easily adjustable control voltage.
• The compact size of the sensors makes them easy to install in
virtually any locations.
H: R+RI core(High efficiency magnetic circuit)

Please contact TDK for applications requiring non-standard
voltages.
M or H model should be used for applications particularly requir-
ing avoidance of effects caused by the sensor lateral surfaces.
Usage conditions should be considered carefully when selecting
model H, which is designed for high sensitivity. Due to low cost,
model L is also used as an out-of-toner sensor.

The most appropriate sensor protrusion length should be
selected during design of the toner/carrier tank.
5 Two character control code using by TDK during sampling.
• Standard ratings include the sensor sensitivity and the output fil-
ter time constant.
