Special Version of SRD960
SRD960 for actuator with rotation up to 300°
This special version of the SRD960 is designed to be
mounted by means of standard attachment kit (like the
EBZG-R) onto rotary actuator with rotation up to 300°.
This special version is made of a standard SRD960 with
new gears.
To be ordered under special version ECEP EP0265
