Mechanical Power Presses-
The Kamco K80 style Rotating Cam Limit Switches are the accepted standard for controlling clutch and brake circuits on Mechanical Power Press controls. These highly accurate, repeatable devices offer simple set up and extreme reliability. By using multiple cams for each critical event and cross checking the contact operation in the press control, no single component failure can cause inadvertent operation of the press. The fact that the Kamco K80 units are typically mounted on the press in an area that is not easily accessible to unauthorized personnel, lessens the chance of accidentally changing (adjusting) critical control settings.
The K80 Chain Break Base can be used in conjunction with the Rotating Cam Limit Switch to detect a broken / slack chain or belt. A switch, held active under normal conditions, allows the press to continue its cycle. If the chain loses tension or breaks, the switch changes state and stops the press from cycling.
Applications using solid state press controls can use the Kamco K80-R Cam / Resolver Combination unit. This device allows the mechanical cams to be used for critical clutch and brake controls while the resolver is used to control automation functions. This method is not only the best solution for safety reasons, it is also the most cost effective.
Note: The information provided above is for reference only. Kamco K80 units when properly applied meet or exceed OSHA 1910.217(c) and ANSI B11.19-1990 standards. Consult your Press Control designer for specific installation and wiring details.
Index Tables-
The K80 Rotating Cam Limit Switch is ideal for use in controlling slow down and/or stop points over the table travel. The unit allows for dwells to be set, based on either direction of travel.
Packaging Machinery-
Applications requiring accurate, repetitive control of cyclical events such as labelers, cartoners, case packers and others are ideal for these units as they offer long life, easy set up and competitive pricing.
Automation Equipment-
Any project requiring feedback or control of rotary and/or rotary to linear motion can implement the K80 Rotating Cam Limit Switches. Devices such as lifts, transfers, shuttles, hoists and more can be accurately controlled using these devices. Connection to the machine must be in such a way that the Rotating Cam Limit Switch turns one revolution or less over the complete machine travel. This can be accomplished via chain and sprockets or with a gear reducer.
Steel Industry-
Applications such as gates, valves, vessels, coil cars, lances and more can be controlled via these industrial hardened units. The simple, rugged design allows these units to be set and forgotten in many steel Steel Mill applications.
