reflective tape has been affixed. It can also be used as a con-
tact-type tachometer by attaching the Z5003 Contact Adapter.

1.1 Product Overview
1.2 Features
Contactless measurement for long detection range
The instrument’s ability to detect speed from up to 50 cm distance al-
lows its use in situations where it would be hazardous to approach the
object being measured.
Easy-grip design
Easy-to-grip design and light weight make the instrument easy to han-
dle.
LCD with a wide field of vie
The FT3405/3406 features a transmissive FSTN liquid crystal display
(LCD), ensuring its readout is easy to read.
Maximum/minimum value hold
Maximum and minimum values are updated continuously so you can
verify variations in rotational speed.
Dust-proof design
The FT3405/3406’s enclosure delivers IP 50-grade protection, allow-
ing it to be used with confidence and peace of mind in environments
characterized by debris (dust, sand, grit, etc.) thrown off by the rotat-
ing object.
Drop Proof
The FT3405/3406 can withstand being dropped from a height of 1 m,
making it less likely the unit will be damaged.
Analog Output/ Pulse Output (FT3406 only)
The FT3406 can be used in trend management applications by con-
necting it to a recorder.
