Electric Cylinders Rod-Type Limit Switch
Electric Cylinders Rod-Type Limit Switch Assemblies
The Rod-Type Limit Switch provides two SPDT switches used to limit the maximum and minimum cylinder extension. The switch assembly mounts to the cylinder tubes for convenient access and leaves the extension shaft free for other purposes. The simple design permits easy installation and maintenance. Independent adjustment allows for quick and easy fine tuning of the travel limits.
Every Electric Cylinder should be installed so that electrical power to the motor is turned off and the brake engaged before the travel limits are reached, or damage to the cylinder can result.
Minimum travel is 6" and maximum travel is 72" for all Electric Cylinders equipped with rod-type limit switches.
Use of Rod Limit Switches in outdoor application with direct exposure to harsh environmental conditions is not advisable. Contamination will prevent the switch from functioning poperly.
