APPLICATION:
Gemco's all new Micro-Adjust Rotating Cam Limit Switch is a pilot device used for heavy duty material handling mechanisms, mechanical presses,* packaging machines, rotary table, and in many other applications where accurate, repetitive, and sequential operations are required in control circuitry.
When motion is expressed in shaft rotation, either through a roller chain, gear train, or directly, the Gemco Rotating Cam Limit Switch makes it possible to open or close independent circuits at any desired angular position.
|
|
MOUNTING OF UNIT
Mount the assembly and couple input shaft to the driving member with the shaft keyway up and in line with the positioning arrow on the bearing end plate. The machine should be in the start cycle position.
ESTABLISHING CAM SHAFT
DIRECTION OF ROTATION
Cam settings should be made with the cam shaft uppermost to the viewer. The picture at the top right illustrates this viewing position and also shows the adjusting tool being applied to the adjusting wheel. Shaft rotation is always established off the right end of the unit even when the input shaft, whether direct or through a gear reducer, is situated at the left end. As an aid to designating shaft rotation when a gear reducer is used, consult page 14 of this catalog section.
CAM SETTINGS
For clockwise rotation set "make" angle with the black dial and break with the red dial for dwell settings less than 180°. Reverse colors for dwells 180° or greater.
For counterclockwise rotation, set "make" angle with the white dial and "break" with the yellow dial. Reverse colors for dwells 180° or greater.
Switch connections should be made in accordance with the illustrations to the right, which incidentally are both clockwise rotating examples.

DESCRIPTION
Precision, rugged duty snap action switches, extremely accurate cam adjustments with a heavy-duty shaft, rugged case and lifetime sealed ball bearings, have been combined by Gemco to provide the most versatile and dependable Rotating Cam Limit Switch available.
NO SPECIAL CAMS ARE REQUIRED
The accurate cam adjustments are made possible by the use of a separate reduction drive in each half of a circuit cam block assembly. This drive provides a 36 to 1 ratio, which means that one revolution of the adjustment wheel will advance or retard the cam set ting by 10 degrees.
For most applications, therefore, no special cams are necessary and settings may be changed at any angular position of the camshaft.
LIFETIME SEALED BALL BEARING allows mounting in any position.
LARGE COVER OPENINGS for ease of wiring.
NO MINIMUM SPEED is specified because snap action contacts are used. Maximum rated speed of the cam shaft is 500 RPM and can be rotated either clockwise or counterclockwise.
Two types of compact integrally MOUNTED GEAR REDUCERS are available with ratios of 1:1 through 600:1. They can also be supplied with speed multipliers up to 1:8.
|
|
TECHNICAL DATA
• The maximum temperature with full electrical load is
185°F. The minimum operating temperature is -50°F
minimum cam adjusting temperature is -10°F.
• Standard Gemco Rotating Cam Limit Switches have a
rating of 50 pounds end thrust and 500 pounds radial load
on standard shaft extensions.
• TORQUE REQUIRED - .6 LB-IN/CIRCUIT.
• REPEATABILITY + OR - 1/4°
SNAP ACTION SWITCHES
All standard Gemco Rotating Cam Limit Switches employ S.P.D.T. precision type snap action switches which provide the advantage of double break contacts and are actuated at a uniform rate to give long life. D.P.D.T. switches can be provided upon request. Any number of circuits from 1 to 40 may be supplied as standard in NEMA 1, NEMA 4, NEMA 7 and NEMA 12 enclosures.
GEMCO MICRO-ADJUST
CAMS PROVIDE UNLIMITED CIRCUIT VERSATILITY
Each switch setting can be adjusted to your circuit requirements. An unlimited selection of circuit arrangements is available with the Gemco Rotating Cam Limit Switch, with no special mounting cams, dogs, etc. for contact settings.

ELECTRICAL SWITCHES
DESCRIPTION
The Gemco Precision Snap Switches are designed for industrial duty applications where compact size, complete reliability and millions of trouble free operations are required.
The housing is molded material, which has excellent resistance to arcing and carbon tracking. The operating button is of molded nylon, a material with excellent wear characteristics.
The button is well guided at the top and bottom to insure accurate repeatability and minimum wear.
Any combination of Single Pole Double Throw or Double Pole Double Throw snap action switches can be supplied with the Gemco Rotating Cam Limit Switch.
The switches are individually mounted and can be readily replaced without the need of adjustment or alignment. All switches have binder head terminal screws, which are accessible for wiring with either stripped, or wire lug connections.
|
NOTE: Refer to Catalog Section 1950 for detailed information pertaining to all Standard and Special Switch Options.
|
|
Switch replacement is recommended every 15 million cycles.

|
SHAFT EXTENSION
The Gemco Rotating Cam Limit Switch can be supplied with the desired shaft extension. The standard shaft extension can be specified in the catalog numbering system on page 8.
To determine the shaft extension symbol, the Rotating Cam Limit Switch must be viewed from the switch side of the assembly as shown.
|
|
The shaft extension can be specified as either:
L= Left shaft extension
R= Right shaft extension
D= Double shaft extension (both ends)
X= No shaft extension opposite the gear box
V= Shaft extension opposite gear box
|
  
|
SWITCH TYPE
The Gemco Precision Snap Switches are specifically designed for industrial duty applications where reliability, ease of wiring and millions of trouble free cycles are required.
The Gemco Rotating Cam Limit Switch can be supplied with either a basic single pole double throw (S.P.D.T.), double pole double throw (D.P.D.T.) or a combination of both types.
A Plug-In Socket can be supplied with either the S.P.D.T. Or D.P.D.T. switches.
NOTE: REFER TO CATALOG SECTION 1950 FOR FURTHER DETAILS ON SNAP SWITCH PARTS AND OPTIONS.
|
|
The type of snap switch can be specified in the catalog numbering system on page 8.
SP = Single pole double throw
DP = Double pole double throw
SPP = Single pole double throw with a plug-in socket
DPP = Double pole throw with a plug-in socket
The Plug-In Socket eliminates error due to disconnecting and connecting wires during replacement of the snap switch. A marking strip is supplied with each plug-in socket for ease of wire identification.
|
Switch Replacement is Recommended Every 15 Million Cycles.

DESCRIPTION
The DRIVE-CHEK is a multi-purpose sub base that is mounted under a chain or belt driven mechanism, The unit serves three purposes; a broken chain or belt detector, a chain or belt tightener, and a shock and vibration isolator.
A Gemco Indicator Switch is provided with each DRIVE-CHEK Unit to indicate when a drive belt or chain failure has occurred. Shock and vibration from the machine to the hinge plate of the DRIVE-CHEK Unit are dampened by coil springs on one end of the hinge plate and an elastomeric support on the other end.
The springs also maintain a constant tension in the drive belt or chain, DRIVE-CHEK is of rugged welded construction and is painted to prevent corrosion. The drive chain or belt can be attached to the mechanism being driven from either above or below the DRIVE-CHEK base.
The DRIVE-CHEK base can be purchased as a separate item for field mounting or factory assembled to the 1980 camswitch. If factory installation is desired, order as separate item and specify as being assembled in the description.
A Gemco single pole double throw switch with mounting plate is supplied with each DRIVE-CHEK unit and can be easily mounted inside the Gemco Rotating Cam Limit Switch enclosure. A Gemco double pole double throw switch can also be supplied.
