FEATURES
1. High-performance compact sync motor
The accurately turning motor is employed to provide for longer
period of measurement.
2. Common for 50/60 Hz power frequency
A lever is used to select 50 Hz or 60 Hz. There is no need to
rearrange the control panel and other signal destinations.
3. Dimensions as per DIN 43700 standard
The units are in the 48 ×48 DIN standard size. They can be fit-
ted in panels and give refined metallic appearance.
4. Easier wiring
The flat terminals (#187) are quick and easy to connect.
5. Rotary indicator
The rotary indicator makes one turn every 2 minutes for quick
monitoring.
6. CE marking
The hour meters satisfy EMC directives (EN50081-2/
EN50082-2) and low-voltage directives (EN61010-1).
TYPICAL APPLICATIONS
Maintenance management of machine tools, automated
machines, control panels, forming machines, medical equip-
ment, generators, compressors, water treatment facilities,
presses, motors, etc.

Notes: 1. Only the black-panel type is UL-recognized and CSA-certified. For this type, specify “U” at the end of the part No. when ordering.
2. If you want the CE marking on your products, specify “CE” at the end of the part No. when ordering.
3. When ordering a UL-listed/CSA-certified, CE-marked product, specify “TH147UCE” for example (in the case of TH14 series, AC 115-120V
type).
