Designed for 440P-C adjustable lever limit switches
Nylon or metal roller
Roller diameter 17.5 mm (0.68 in.) x width 7 mm (0.28 in.)
Lever radius adjustable 45…90 mm (1.77…4.54 in.)
Lever length 84 mm (3.31 in.)
Includes Philips head screw
Principles, Standards, and Implementation
Operating specifications must be followed. Actuators should
be displaced beyond the point where direct opening action
occurs. If adjustable actuators become loose they may defeat
the direct opening action feature of the limit switch. These
devices are not to be used to directly control a motor.
IMPORTANT: Installation of Allen-Bradley limit switches should be in
accordance with local and/or national codes. Servicing
energized industrial control equipment can be hazarous if
not in accordance to recommended safety procedures.
Instructions
1. Insert Philips head screw through the adjustable lever arm
slot.
2. Align the Philips head screw with the operating head shaft
hole.
3. Position the adjustable lever arm to the desired length.
4. Tighten the Philips head screw to 1.4…1.5 N•m
(12.39…13.28 lb•in).

Mounting Dimensions [mm (in.)]
ATTENTION: Under no circumstances must the switch
be actuated beyond the mechanical travel
specified. Serious damage to the device
and property could result.
Maintenance
These devices require little maintenance, but routine visual
inspection is recommended to keep foreign debris from
collecting on the exterior actuators and rollers.
Removing the operator head is not recommended as loose
internal components may be lost or improperly re-installed.
Actuation Guidelines
The method of actuation and over travel has significant
influence on the service life of the limit switch. To maximize
the service life, it is recommended to provide an actuator with
a 30° pressure angle and a surface hardness of RC-45 max.
