1. Safety
Sensor operation assumes knowledge of the operating instructions.
1.1 Symbols Used
The following symbols are used in these operating instructions:
Indicates a hazardous situation which, if not avoided, may result in minor or moderate
injury.
Indicates a situation that may result in property damage if not avoided.
Indicates a user action.
iIndicates a tip for users.
Measurement Indicates hardware or a software button/menu.
1.2 Warnings
Connect the power supply and the display/output device according to the safety regulations for electrical
equipment.
> Risk of injury
> Damage to or destruction of the controller and/or the sensor
Avoid shocks and impacts to the sensor and controller.
> Damage to or destruction of the controller and/or the sensor
The supply voltage must not exceed the specified limits.
> Damage to or destruction of the controller and/or the sensor

1.3 Notes on CE Marking
The following apply to the induSENSOR MSC7401 / 7802 / 7602 series:
- EU Directive 2014/30/EU
- EU Directive 2011/65/EU, “RoHS” Category 9
Products which carry the CE mark satisfy the requirements of the EU directives cited and the European
harmonized standards (EN) listed therein. The EU Declaration of Conformity is available to the responsible
authorities according to EU Directive, article 10, at:

The measuring system is designed for use in industrial environments and meets the requirements.
1.4 Intended Use
Das induSENSOR MSC7401 / 7802 / 7602 measuring system is designed for use in industrial environments.
It is used to control inductive displacement sensors based on the LVDT principle (Linear Variable Differential
Transformer) and for operation with LDR displacement sensors.
- The system must only be operated within the limits specified in the technical data, see 2.3.
- The system must be used in such a way that no persons are endangered or machines and other material
goods are damaged in the event of malfunction or total failure of the system.
- Take additional precautions for safety and damage prevention in case of safety-related applications.

2. Functional Principle, Technical Data
2.1 Functional Principle
The MSC 7401 / 7802 / 7602 series are single- and multi-channel miniature sensor controllers for the opera-
tion of inductive displacement sensors based on the LVDT principle (full bridge) and for half-bridge sensors.
An electronic oscillator supplies the primary coil with an alternating current of constant frequency and ampli-
tude. For optimal control of the respective sensors, the frequency and the supply voltage can be set, see 5.
The demodulator electronics transforms the signal of the two (secondary) coils into the set output signal. With
the setting possibilities for zero point and gain, the user can adapt the equipment to the task to be performed,
see 5.
The output signal increases, when the plunger is moved into the sensor. If the reverse effective direction is
required (i.e. the signal becomes smaller when the plunger is inserted), replace the connections sec+ and
sec-, or make the according setting in the controller, see 5.3.4.
