Panasonic FT-H20W-M2 User Manual

FT-H20WSERIES

FLEXIBLE HEAT-RESISTANT FIBER

Conventional models FT-H20W series

A bending radius of R10mm is possible

even in high temperature environments

Withstands temperature up to 200C.
Sensing is now possible in high temperature environments, such as
detecting the presence of ICs in a high temperature handler.

By utilizing a PTFE exterior coating, bends of R10mm are possible,
even in high temperature environments. Cabling can be laid out freely,
thus saving space.

Fiber Cable Types of 1m and 2m Lengths Are Available

Bending Radius R10mm for Space SavingHeat-resistant Temperature 200C

Fiber cables can be selected for your specific applications, from fiber
cable types of 1m (FT-H20W-M1) and 2m (FT-H20W-M2) lengths.

PRECAUTIONS FOR PROPER USE

SENSING CHARACTERISTICS (TYPICAL)

Parallel deviation

• The bending radius of the fiber cable must be R10mm or more.
If the fiber cable is bent at a smaller bending radius, the sensing
capability will deteriorate.

• Do not bend the fiber cable at the root of the fiber head.

• Do not install the fiber cable on a movable part.

• In order to protect the amplifier, use by keeping 150mm, or more,

of the heat-resistant fiber cable part at normal temperature.

Protect the amplifier from heat radiation or hot air.

• Keep the fiber head surface intact. If it is scratched or spoiled, the
detectability will deteriorate.

• If the fiber head surface is dirty, wipe off the dirt with a clean soft
cloth moistened with water.

(Do not use any organic solvents.)

• Do not use the fiber head surface in places where it may come in
direct contact with water. A water drop on the fiber head surface
deteriorates the sensing.

• Ensure that any strong extraneous light is not incident on the
receiving face of the fiber head.

• Do not apply excessive tensile force of the fiber cable.
(The excessive tensile force should be 19.6N or less.)

• Take care that the sensor is not directly exposed to fluorescent
lamp from a rapid-starter lamp or a high frequency lighting device,
as it may affect the sensing performance.

• Avoid dust, dirt, and steam.

• Take care that the sensor does not come in direct contact with

water, oil, grease or organic solvents, such as, thinner, etc.

• The tightening torque must not exceed the values given below.
