Brake type : SB-004 Brake type : MB-003-005
●
Use fast braking action for lifting devices or
for better stopping accuracy.
●
DC braking capacity (for DC coil loading)
exceeding 5 times the braking current shown
on the name plate is recommended for the
fast braking action.

Note 1: A rectifier is supplied separately for SB-
004.
Note 2: A rectifier is built in the brake of motors
for MB-003-MB005. (A rectifier is
supplied separately for water-proof
type.)
Note 3: Do not open water-proof dust-proof box
for water-proof type, otherwise
electrical shock, fire or damage to the
equipment may result.
Note 4: Rectifier, capacitor are not water-
proofed for water-proof type.
