Telescopic arm shown installed

Bulletin 440P-WM5 Telescopic Arm

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 telescopic arm limit switches

• Telescopic arm diameter 10 mm (0.39 in.)

• Telesopic arm adjustabable 206…801 mm
(8.11…31.54 in.)

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.

ATTENTION: Operator heads with adjustable actuators

should NOT be used for safety
applications.

Instructions

1. Remove old telescopic arm by holding the rubber gasket at
the base of the telescopic arm and turning the telescopic
arm counter-clockwise.

2. Thread the replacement telescopic arm onto the threaded
post shaft extending vertically from the operator head.

3. While holding the rubber gasket at the base of the
telescopic arm torque the telescopic arm clockwise to
1…1.4 N•m (8.85…12.39 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.
