2. Introduction
Th
e PL25/PL60 is a DIGIRULER read head unit with cable, which,
together with the SL110/SL130/SL331 scale unit and MJ100/MJ110
interpolator, forms a position/displacement measuring system.

Features
• Th
e non-contact read head and scale unit is highly resistant to
vibrations, shocks and other harsh workshop conditions.
• Th
e head-scale clearance allows for a great tolerance, making
for easy installation.
• Shorter delay time in signal processing as compared with the
preceding models.
• Resolution PL25 : 10 μm / PL60 : 5 μm
1-2. Operating cautions
• Do not open the cover of this device or put your hand inside.
Otherwise the internal circuit may be broken by static
electricity.
• Th is device is not explosion-proof. Do not use it in the
atmosphere of fl ammable gas.
• Th is device is not vibration resistant. Do not use it in a place
where it is subject to shocks. (Excluding the head assembly)
1-3. Installation
• Use the PL25/PL60 in the temperature range of 0 to +45°C.
Do not expose it to the sunlight or source of heat. A well-
ventilated place is preferable.
• Install the PL25/PL60 at least 0.5 m away from noise sources
such as large-power relays, high-voltage sources, large-current
switch, Inverter high electric power.
• Mount the scale unit away from the magnetic source. (External
magnetic fi eld: 3.0 mT)
• Separately route the head cable and output cable from the
power line.
• When the system is exposed to cutting chips, oil and coolant,
provide a cover. Some coolants may aff ect the functions of
product. Please provide necessary protections.
