The Roller Lever Switch employs a system which allows selection of the operation of only one side (left or right) or both sides without use of any tools. Operating Position Mark (arrow) Bearings The copper-alloy bearings ensure long life expectancy. Receptacle The plug-in type receptacle provides adequate space for wiring. Conduit Opening *, * G / threads featuring high sealing property are used. (Refer to Limit Switch Connectors for details on SC connectors). A terminal box with /-NPT threads is also available on request. Sealed Gasket The employed full-cover method prevents the gasket from direct exposure to oil or water spray. Roller The actuator is made of hardened stainless steel and excels in resistance to wear. Lever With the Roller Lever Switch, the lever can be installed anywhere in a 0 range (80 if the lever is reversed and attached to the shaft). Oil Seal Improved sealing property is ensured with a double-seal construction (a oil seal plus an X-ring seal). Switch Box Boasts long life expectancy (0 million mechanical operations or more with the -pole Double-break Switches and 0 million mechanical operations or more with the DPDT Double-break Switches). Ground Terminal Screw A ground terminal is provided to enhance safety. Switch Box Screw A Phillips screw is used to secure the switch housing for ease of use, and features a measure to prevent the screw from coming off. Easy-maintenance Block Mounting Block makes it possible to easily assemble or disassemble the head, switch body, and receptacle of the DA-@N by tightening or loosening the attached screws. Actuator Switch box Head Receptacle Note:. NBR is used in rubber components. Fluoro-rubber sealed types use fluoro-rubber.. For Roller Levers, there is some lever play in the free position (about mm), but this is due to the structure of the head and does not interfere with performance. *. A Receptacle and Terminal Box with /-NPT threads are also available for the North America market. *. The thread indication has been changed from PF/ to G/ accompanying the JIS B 00 revision. This changes applies only to the indication; thread sizes and pitches have not been affected. 7

13 Head and Lever Positions The operating head can be positioned and locked in any of four 0 positions and a lever can lock in any position through 0 around the shaft of the Limit Switch. Furthermore, the lever can be reversed and attached to the shaft (refer to the figures below on the right hand side). Therefore the is compatible with a wide movement range of a dog. A Fork Lever Lock can be used with maintained models (DA-000N) only. Remove the head from the Switch by loosening the screws (the screws can be loosened but not removed from the head). The operating head can be positioned and locked in any of four 0 positions. The lever can lock in any position through 0 around the shaft. The lever can be reversed and attached to the shaft, in which case the switching operation should complete in a range of 0 to operating position Four, M x 0 operating position There are four kinds of fork lever locks. The position of each is different. It is possible to use DA-E00 through DA-E0 levers instead, if they are reversed before attaching. They can be used with DA-@@0N models only. DA-E00 DA-E0 DA-E0 DA-E0 By loosening the Allen-head bolt on an adjustable lever or rod lever, the length of the lever can be adjusted.

14 Safety Precautions Refer to Safety Precautions for All Limit Switches. Operating Environment Precautions for Correct Use Seal material may deteriorate if a Switch is used outdoor or where subject to special cutting oils, solvents, or chemicals. Always appraise performance under actual application conditions and set suitable maintenance and replacement periods. Install Switches where they will not be directly subject to cutting chips, dust, or dirt. The Actuator and Switch must also be protected from the accumulation of cutting chips or sludge. Not Suitable Suitable Lighting Mode Selection of Indicators (SPDT only) The lighting mode of the operation indicator can be changed easily between two modes: lighting when the Switch is operating and lighting when the Switch is not operating. Lights When Not Operating * Lights When Operating * Power supply Internal circuits Power supply Built-in switch Constantly subjecting a Switch to vibration or shock can result in wear, which can lead to contact interference with contacts, operation failure, reduced durability, and other problems. Excessive vibration or shock can lead to false contact operation or damage. Install Switches in locations not subject to shock and vibration and in orientations that will not produce resonance. The Switches have physical contacts. Using them in environments containing silicon gas will result in the formation of silicon oxide (SiO) due to arc energy. If silicon oxide accumulates on the contacts, contact interference can occur. If silicon oil, silicon filling agents, silicon cables, or other silicon products are present near the Switch, suppress arcing with contact protective circuits (surge killers) or remove the source of silicon gas. Changing the Operating Direction Roller Lever Switch The head of the side rotary type can be converted in seconds to CW, CCW, or both-way operation. Follow the procedures on the right hand side for conversion (not applicable to the Maintained, Sequential Operating, Center Neutral Operating Switches). Operating Part (Rear of Head) Operating position arrow marks Procedures. Dismount the head by loosening the four screws that secure it.. Turn over the head to set the desired operation (CW, CCW, or both). The desired side can be selected by setting the mode selector knob shown in the figure. This knob is factory set to the CW+CCW (both-way operation) position.. When set to the CW position, the head rotates in clockwise direction. When set to the CCW position, the head rotates in counterclockwise direction. In either case, be sure to accurately align the arrow mark to the setting position. Built-in switch Internal circuits *. The lamp is lit when the actuator is at the free position. The lamp will be off when the contacts of the Limit Switch have been actuated and snapped to each other at the operating position. *. The lamp is lit when the contacts have been released and snapped only from the operating position. Change the lighting mode as follows: In either case, the lamp will not light when the load is ON.

15 Screw Tightening Torques for Heads and Switch Boxes To maintain the high sealing capability of the Limit Switch, tighten the screws for the head and switch box with the following torques: Head (four -mm M screws):. to. N m Switch box (two 0-mm M screws):. to.7 N m Solderless Terminals The DA-@N with DPDT double-break incorporates solderless terminals. Operation The operating methods, cam and dog shapes, operating frequency, and overtravel (OT) have a significant effect on the service life and accuracy of the Limit Switch. The shape of the cam should be as smooth as possible. A marginal overtravel (OT) value should be set. The ideal value is the rated OT value x 0.7. The actuator should not be remodeled to change the operating position. Connectors To satisfy IP7, apply sealing tape to the connector. Appropriate external diameter of cables is. to dia. Use OMRON s SC-@M Series. Tighten the Connectors to a torque of.8 to. N m. Maintenance and Repair The user must not maintain or repair equipment incorporating any DA-N model. Contact the manufacturer of the equipment for any maintenance or repairs required. Appropriate Tightening Torque A loose screw may cause malfunctions.
