Available in four sizes, the FRB Series Rotary Actuator is rated up to 33 in-lb of force and offers rotation angles of 90, 180 and 270 degrees. This vane-type actuator includes standard stainless steel shafting, as well as optional position sensing. It also enables low-pressure operation—featuring a minimum operating pressure ranging from 22 psi with the larger bore sizes and 29 psi for the smaller bores.
At its largest size, the FRB Series accommodates loads up to 30 N (radial) and 25 N (thrust). Its round profile sensors feature surge suppression, polarity protection, an LED indicator and extremely fast switching speeds. These slide into mating 4-millimeter keyhole slots and are easily positioned and locked into place with set screws. Units integrate durable materials, including hard-anodized aluminum front and rear end covers, carbon steel screws and special Nitrile Buna rubber (NBR) seal and washers.
