MSI-HS Series Linear Position Sensor with SSI Output

The MSI-H series is a rod-type, high-precision, absolute, non-contact magnetostrictive linear position sensor with a measuring range from 25 to 3800 mm.

Position measurement is performed using ring-type position magnets that move along the waveguide without physical contact.

The sensor flange is made of high-quality stainless steel and designed for long-term operation in demanding industrial environments.

Interface

SSI PROTOCOL TIMING DIAGRAM

This oscillogram shows a standard SSI transmission.

Channel 1 reads the clock signal "Clock (+)"

Channel 2 reads the binary code "Data (+)"

The interval between two transmissions (Monoflop time) is 16 microseconds. This performance corresponds to Temposonics V series sensors.

As a result, our sensors are compatible with all controllers currently available on the market.**

Connection example

Setting

When replacing a failed sensor, recalibration of the equipment is required in most cases. This can be done in two ways:

  • If the customer’s machine has a calibration function, after replacing the sensor, the operator assigns the new end positions to the machine’s control system by moving the mechanism in manual mode.
  • Using the MSI-253 135 programmer, the new zero point value can be programmed directly into the sensor. The procedure is similar to the first method, but in this case, the value is assigned to the sensor rather than to the customer’s machine.
