Vehicle & Off-Highway Machinery Control Systems (M-Series)

DSEM835

3.5" Programmable Display
The DSEM835 is a 3.5” programmable display designed for use on vehicles and off highway machinery. The DSEM835 provides users with outstanding flexibility. The DSEM835 is configured using CODESYS 3.5.
OVERALL SIZE
112.5 mm x 115 mm x 49 mm / 4.43 ” x 4.53 ” x 1.93 ”

WEIGHT
< 1 kg
2.20 lb

CUT-OUT
82 mm (3.23 “) hole is suitable.
If a punch or milling machine is available, adding ‘flats’ at 74 mm (2.91 “) spacing serves to prevent rotation of the device in the panel cut-out.
