Photoelectric Laser Displacement Sensors

Principles Of Operations
The VDM70 series are analog displacement photoelectric
DC sensors using time of flight technology to measure
Quick Disconnect distance. The measured values are made available through
standard RS-422 interface or SSI compatible interface
which are capable of providing precise positioning with
12-Pin M16 Type millimeter accuracy and high resolution. The VDM70 series
feature a 3-button keypad which controls all functions and
Male Receptacle End View parameters. The VDM70 series also feature a 2-line LCD
F G M H J K
display which shows programming information and error
codes as well as providing continual distance monitoring.

Photoelectric Laser Displacement Sensors

Principles Of Operations
The EDM series are analog displacement photoelectric
DC sensors using time of flight technology to measure
Terminal Connection distance. The measured values are made available through
standard integrated interfaces which are capable of
providing precise positioning with millimeter accuracy and
high resolution. Each EDM sensor features an Infrared
