All E50 Limit Switches consist of two modular, interchangeable plug-in components: operating head and a solid state
switch body. Operating heads (side rotary, top and side
push, and wobble stick) are mounted on top of the switch
body in any of four positions. All assembled limit switches are
rated NEMA 3, 3S, 4, 4X, 6, 6P and 13. Obtain renewal parts by
ordering the catalog number labeled on each of the two limit
switch components.
NEMA ICS 2-225 describes preferred installation recommendations which ensure greatest reliability and longest life expectancy for Industrial Limit Switches.
INSTALLATION
WARNING
DO NOT INSTALL OR PERFORM MAINTENANCE ON THIS
DEVICE WHILE THE CONTROLLER IS ENERGIZED. DEATH OR
SEVERE PERSONAL INJURY CAN RESULT FROM CONTACT
WITH ENERGIZED EQUIPMENT. VERIFY THAT NO VOLTAGE IS
PRESENT BEFORE PROCEEDING WITH INSTALLATION OR
MAINTENANCE. Only qualified persons, as defined in the
National Electric Code, who are familiar with the installation,
maintenance and operation of this device and the equipment
onto which is to be installed, as well as applicable local, state
and national regulations and industry standards and
accepted practices regarding safety of personnel and the
equipment safety should be permitted to install, maintain or
operate this device. These instructions are provided only as
a general guide to such qualified persons and are not allinclusive. They do not cover every application or circumstances which may arise in the installation, maintenance or
operation of this equipment. Users are advised to comply
with all local, state and national regulations and industry
standards and accepted practices regarding safety of
personnel and the equipment safety.

TORQUE REQUIREMENTS FOR LIMIT SWITCH ASSEMBLY
Tighten the operating head screws to a torque value within the
following ranges to ensure and maintain the Enclosure Type
Ratings for the assembled limit switch.
Operating Head Screws — Tighten to ensure contact of head
to switch body: 14 - 18 lb. in.
OPERATING HEAD POSITIONING
Heads can be mounted on the switch body in any of four
directions, 90° apart. Torque screws according to requirements on page 1.
OPERATING HEADS — SIDE ROTARY
The operating mode (CW, CCW or CW and CCW) of these
spring return operating heads is easily changed without
tools as shown in the illustration. Remove the head from
switch body. Pull out the plunger and turn until its position
matches that shown on the diagram for the desired operation mode. Levers are adjustable to any angle (360°). The
operating shaft screwdriver slot can be used to maintain
shaft position during lever installation.
OPERATING HEADS — PUSH OPERATED
These spring return top push or side push operating heads
are available in pushbutton and roller styles.
The push roller style can be converted from vertical to
horizontal operation or vice versa. Pull roller out of the head
until it can be rotated 90° to the desired orientation. When
released, it will snap into the set position.
The Maintained Contact head has the reset pushbutton
located opposite of the actuator pushbutton.
Push Operational Head
OPERATING HEADS — WOBBLE STICK
These spring return, top operated heads use different rodtype operators to detect motion in any direction perpendicular to the operator. The operator screws onto the threaded
head stub.

REPEAT ACCURACY
The type of operating head used on an assembled limit
switch determines repeat accuracy for the switch assembly.
Assembled limit switches, without rollers used on operating
heads or levers, have a repeat accuracy as listed in Table 1
only.
Assembled limit switches with rollers used on operating
heads or levers have a repeat accuracy determined as
follows: add the repeat accuracy tolerance of Table 1 for the
type of operating head used to the concentricity tolerance of
Table 2 for the type of roller used on the lever or operator.
The combination of these two tolerances is the limit switch
repeat accuracy.
