Applications

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.

• Straight Drive and Right Angle Gear Reducers

• Timing Dial and Timing Dial Window

• Electrical Wiring per Customer’s Speciﬁ cation

• Motor Driven Rotating Cam Limit Switch with AC or DC for Adjustable Speed Drives

• Potentiometer driven off the Camshaft

• Spring Return Mechanism

• Plug-In Socket

• Double Ended Shafts

• Pilot Lights

• 3 Way and 4 Way Air Valves directly interchangeable with switches

• Special Conduit Opening

• Special shaft extensions and keyway

• Adjustable Coupling (See Catalog Section

3001)

• Special Cams & Large 6” Cams for Higher Resolution

• Combination Adjustable-ln-Motion and MicroAdjust Circuits (see Catalog Section 1981)

• Electric Clutch and/or Brake

• Separate Terminal Strips

• Add-A-Cam Feature

• Factory Adjustment of Cams Available

• Open Type Units

Mounting of Unit

FRONT SIDE

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 Camshaft Direction of Rotation

Cam settings should be made with the Camshaft 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

SWITCH SIDE

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

Technical Data

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 setting by 10 degrees.

• 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 +/- 1/4°

Snap Action Switches

All standard GEMCO Rotating Cam Limit Switches employ SPDT precision type snap action switches which provide the advantage of double-break contacts and are actuated at a uniform rate to give long life. DPDT 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.

Each switch setting can be adjusted to your circuit requirements. arrangements is available with the GEMCO Rotating Cam Limit Switch, with no special mounting cams, dogs, etc. for contact settings.

GEMCO Microadjust Cams Provide Unlimited Circuit Versa

An unlimited selection of circuit

tility

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 Camshaft 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.

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.

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.

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.

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

Special Conduit Openings

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.
