1. Introduction
This user manual describes the ZMID4200MLIN01201 Linear Application Module. This application module is
designed to measure a linear movement of a sensor target using the ZMID4200 Inductive Position Sensor IC,
which is connected to an application-specific coil design and located on the Linear Application Module Sensor
PCB.
For a first evaluation of the Application Module, the kit contains a target holder to locate and move the sensor
target over the sensor coils. Using the separately available ZMID-COMBOARD, the Application Module can be
connected to the user’s computer. Using the ZMID4200 EVK Application Software, the module can be
programmed and configured. To download the software and its user manual, visit the
www.renesas.com/ZMID4200 web page.
After the first evaluation of the Application Module performance, the Linear Application Module Sensor PCB and
the sensor target can be mounted on any application for rapid prototyping. The design data of the Application
Module is available (see section 1.1.3). The following sections describe technical details of the Application
Module.

in the ZMID4200 Datasheet.
1.1.3. Design Documentation
The design data are available on the Renesas webpage (see page 1) or can be requested via Renesas’ sales
team (see contact information on the last page). The support package contains the design files as well as the
fabrication outputs for the ZMID4200MLIN01201 Linear Application Module including the following:
■3-D Data (.step)
■Fabrication outputs (Gerber)
■PCB design files (Altium)

1.2 Getting Started
1.2.1. Module Hardware Connections
Follow these procedures to set up the kit as shown in Figure 1:
1. Connect the Application Module to a ZMID-COMBOARD or to an external application using the sensor cable
using the connectors shown in Figure 1. See Table 3 for the details for the connectors.
2. If using the ZMID-COMBOARD, connect it to the user’s computer using a USB cable or power up the user’s
application controller.

Figure 2. Target Holder Assembly
1.2.3. Sensor Configuration and Calibration
The Application Module is preconfigured for the mechanical configuration when using the target holder. If the
Linear Application Module Sensor PCB is mounted on any existing application with a mechanical configuration
different from the Application Module mechanics, the sensor IC must be configured and programmed for the new
setup. This can be done using the ZMID-COMBOARD and the ZMID4200 EVK Application Software.
2. Application Measurement
The Application Module was measured to assess the typical sensing performance. For positioning the target at
different positions and displacements, a four axis measurement table was used. At each displacement position,
the digital output value was read to obtain the data shown in the following graphs.
2.1 Output Measurement at 1.0mm Airgap
For this measurement, the sensor was calibrated at an airgap of 1.0mm. The sensor gain, offset, and slope were
configured for the measurement range, and the output was linearized.
