1. Operating Cautions
• Do not use the unit in places where it may receive excessive shocks. Otherwise the inside of
the unit may be damaged or the unit may become unable to produce normal output signals.
• Be sure to turn off the power before connecting or disconnecting connectors in order to
prevent damage or misoperation.
• After mounting the measuring unit, insert the connector into the display unit until it
locks. Be sure to turn off the power switch before connecting or disconnecting the
connector.
• Locate the measuring unit (head built-in portion) at least 10 cm away from a strong
magnetic source. (Do not exceed 5 mT in parallel magnetic fields.)
• Do not forcibly pull the cable for connecting or disconnecting, or it may cause breakage.
• The measuring unit is short circuited to the frame GND (ground terminal) of the display
unit by shield wire of the cable. When the measuring unit is used with an other signal
processing device on a machine tool, etc., be aware of the ground level.
• The N-type measuring unit has an unsealed spindle for use in mechanical devices and
measuring rooms having a favorable work environment.
Due to the low measurement force, the N-type cannot be used with the spindle directed
upward.
• The P-type measuring unit is dust-proof, drip-proof, and oil-resistant making it suitable
for use in environments subject to chips, cutting oil, and machine oils. However, avoid
immersing the P-type in cutting oil, etc., as it is not of a water-proof structure.
• Adhesion of cutting oil, etc. which increases in viscosity after drying, may hinder accurate
spindle motion. Remove them with water or tepid water. Then apply machine oil or the
like to the spindle.
• The P-type measuring unit is provided on the sliding portion of the spindle with an anti-
drip/dust seal of nitrile rubber. Spindle movement may be impaired by exposure to cutting
oil, water, etc. that may remove oil from the spindle surface.
• Recommended calibration interval 1 year.

2. Mounting Instructions
• Be sure to chuck the stem for mounting the measuring unit. If other portion of the measuring
unit needs to be chucked, avoid chucking the name label portion (where the head is built
in) and its neighborhood (Fig. 1).
If the measuring unit is mounted on another device, ensure that the measuring unit is free
from contact with mount screws.
• If excessive torque is applied on the spindle when screwing in the feeler, the internal
mechanisms can be damaged. Therefore, screw in the feeler with your hands, and never
use a tool.
Except when using a flat feeler, it is recommended to either attach the spring washer
(nominal size: 2.5) or use a screw lock to prevent loosening of the feeler. (Tightening
torque reference value: 0.05–0.06 N·m)
• The measuring unit comprises ball bearings. Therefore, chucking the stem of the measuring
unit too tightly when mounting may damage the spindle and prevent its smooth motion.
• A holder of dimensions as shown in Fig. 2 may be used to mount the
measuring unit, tightening the screw to about 4 N·m torque.
• Since mounting parallelism affects the measuring accuracy, adjust the parallelism to within
0.3 mm in relation to 100 mm displacement by means of mount bracket (or sleeve).
• Fix the cable in a suitable position to prevent possible cable breakage. Never handle the
cable by forcibly pulling or bending it. (Inside bend radius 50 mm or more)
• If the spindle is to be fixed to the machine, use coupling DZ-191 which is optionally
available. Refer to the DZ-191 Instruction Manual regarding the mounting procedure.
• After the stem is secured, do not apply force in the rotational direction. This could cause
a failure.

5. Measuring unit output signals
The signals output from this measuring unit are phase A/B/Z signals in the form of voltage-
differential line driver output compliant with EIA-422.

Phase A

Phase B

Phase Z

The reference point is the synchronized reference point that is at Hi level when the phase A
and phase B are at the Hi level.

Output signals at maximum response speed (at approx. 250 m/min)

200 ns (5 MHz)

Phase A

Phase B

50 ns

Before using, check that the minimum input phase difference of the control device connected
to this measuring unit or the counter is smaller than 50 ns (phase A cycle: 200 ns, 5 MHz).

* The minimum phase difference can be modified under special specifications.

(See “5-1. Output signal phase difference”)

5-1. Output Signal Phase Difference

The travel amount of the measuring unit is detected every 50 ns, and the phase difference
proportional to the amount traveled is output. The phase difference changes in integer multiples
of 50 ns.
Also, the minimum phase difference for the phase A and phase B is 50 ns.
