ATTENTION

To avoid electrical shock and unintended
operation of equipment, disconnect all power
to the limit switch and the controlled
equipment before proceeding with any repair
or adjustment of the limit switch.

General Data

• Designed for 440P-M metal rod lever limit switches

• Rod lever sweep range up to 40°

• Rod lever diameter 3 mm (0.12 in.)

• Rod lever length 160 mm (6.3 in.)

• Rod lever max extension 143 mm (5.63 in.)

• Includes collar and one Allen 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.

Installation of Allen-Bradley limit switches
should be in accordance with local and/or
national codes. Servicing energized industrial
control equipment can be hazardous if not in
accordance to recommended safety
procedures.

Operator heads with adjustable actuators
should NOT be used for safety applications.

Approximate Dimensions [mm (in.)]

Instructions

1. Position the collar on the shaft to the desired position.

2. Tighten the collar shaft Allen head screw to 2.7…3.7 N•m
(23.9…32.75 in•lb).

3. Insert the metal rod lever into the collar shaft hole.

4. Adjust the position of the metal rod lever to the desired
length.

5. Tighten the adjustable rod lever Allen head screw to

1.5…2.1 N•m (13.28…18.59 in•lb).

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.
