Magneto-Electric Rotation Detector Frequently Asked Questions

To branch the signal of MP981.

To branch the output

It is possible when the distance to the branching point is short (within 5m). However, please use a connection with an input impedance of 20kΩ or higher.

When outputting to the TM2100 series, branch the SIG, COM, and shield wires from the first terminal block and connect them to the second device (see Figure 1). Since connecting the two devices with long signal wires can easily introduce noise, please use a dedicated amplifier (PA-150) (see Figure 2).

Figure 2. In the case of the TM series and PA150.

Attention When using materials such as bakelite for the installation jig of MP-981, please ensure that the earth terminal of the TM-2100 series (first unit) is connected to the earth ground. If a conductive material such as metal is used and the earth ground is established, do not connect the earth terminal of the TM-2100 series (first unit) to the earth ground. Please connect the earth terminal of PA-150 and the earth terminal of the TM-2100 series (second unit) to the earth ground.

次のようなときにご利用ください。

• If the cable length is increased, there is a risk of noise being picked up.
• If you want to branch the signal.
• If you want to insert a relay into the cable.

For detailed specifications of the PA-150, please refer to the catalog and user manual.
