■ Types of actuators Shape Class. TECHNICAL TERMINOLOGY & CAUTIONS FOR USE Pretravel (P.T.) Overtravel (O. T.) Operating Force (O. F.) Vibration Shock Features Pin plunger Small Small Large Outstanding Appropriate for linear short-stroke action. Pin plunger acts directly on snap action mechanism, enabling high-precision positioning. Amount of movement after operation is smallest among all of the actuators, however, so reliable stopper is required. Spring small plunger Small Medium Large Excellent Used in much the same way as the pin plunger, but is easier to use because the amount of movement after operation is larger. Spring short plunger Small Medium Large Good Pin plunger is short, with large plunger diameter that makes centering easier. Like small spring plunger, amount of movement after operation is large. Panel attachment plunger Small Large Large Good Secured to panel with hex or lock nut; used as manual or mechanical plunger. Amount of movement after operation is extremely large and operation point can be adjusted by changing attachment position. Can be used in combination with low-speed cam. Panel attachment roller plunger Small Large Large Possible This is the panel attachment type with a roller, and can be used with fastmoving cams and dogs.. Hinge lever Large Medium Small Possible Little force required for operation. Appropriate for use with low-speed cams and dogs; has large stroke. Lever available in various shapes to fit operating unit. Simulated roller lever Large Medium Small Possible Tip of hinge lever is bent into a semi-circle, enabling use as a simple roller type. Leaf lever Large Large Small Excellent Play in lever is used to assure maximum stroke. Construction provides for space where lever is attached, for outstanding resistance to freezing. Hinge roller lever Large Medium Small Possible This is a hinge lever with a roller, and can be used with high-speed cams and dogs. The force required for pin plunger action is lighter than that of the lever, and the stroke is longer. One way action hinge roller lever Medium Medium Medium Possible This is hinge roller lever type, and can operate in relation to an operating unit from a one way direction, but the roller is bent from the opposite direction and cannot move. This can be used to prevent reverse-direction action. Leaf spring Medium Medium Medium Good This has a leaf spring with offset yield force and has a large stroke. Ideal for driving low-speed cams and cylinders. Fulcrum is fixed for high precision. To prevent leaf damage, movement after operation must be within specified value. Roller leaf spring Medium Medium Medium Good This is a leaf spring with a roller, and can be used with high-speed cams. (O.C. reversed action groove type) Reverse-action hinge lever (O.C. reversed action groove type) Reverse-action hinge roller lever (O.C. reversed action groove type) Reverse-action hinge roller short lever Large Small Medium Excellent Medium Medium Medium Excellent Small Medium Large Excellent This is used for low-speed, low-torque cams. The lever comes in various shapes to fit the operating body. This is a reverse-action hinge lever with a roller and is appropriate for cam operation. Excellent resistance to vibration and impact when not engaged. This is a shorter version of the reverse-action hinge lever with a roller and has a larger action force, but is appropriate for cam operation with a short stroke. Excellent resistance to vibration and impact when not engaged. The plunger is constantly pressed down by a coiled spring, and operating the lever induces reverse action. Because the plunger is depressed when not engaged, vibration and shock resistance are excellent. Pressing the plunger too far does not cause abnormal force to be applied to the switch mechanism, so a stable service life is assured. Rotating-action type Large Large Small Possible This is a rotating, light-action type that is ideal for detecting paper, coins, and similar objects. 13
TURQUOISE SWITCHES TURQUOISE SWITCHES High Environmental Resistance Turquoise Colored Seal <strong>Switches</strong> Against dust, gas and water Elastomer double molding technology, an industry first, and ultrasonic swaging technology contribute to uniform sealing in high production quantities IP67 type (immersion protected) Broad lineup: J, S and V models make up over 1,000 types.

Cross section of the rubber cap Cover Rubber cap Cover Rubber cap Protective grade of body: IP67 Dust and immersion protected type Rubber cap Cover Body Ultrasonic swaging process: A process which bends the material through ultrasonic vibration. Cross section of wire leads type Conforming to IP67 Common for dust protected and immersion protected type Rubber cap Elastomer double molding Elastomer double molding Elastomer: Elastic thermoplastic resin Epoxy resin (internal) Terminal position conforming to IP67 Wire leads Elastomer double molding The industry's first elastomer double molding technology is used to mold the elastomer to the switch body. A reliable seal of the body and cover is achieved. ■ Construction The dust protected type (IP50) and the immersion protected type (IP67) pass the following tests, respectively. The immersion protected type is especially tested to check for the entry of water after soaking for a certain period of time. Avoid operation where they are immersed in water. 14 [Test conditions] • Dust protected type (IP50) The powder circulation pump may be replaced by other means suitable to maintain the talcum powder in suspension in a closed test chamber. The talcum powder used shall be able to pass through a square- meshed sieve the nominal wire diameter of which is 50 µm and the nominal width between wires 75 µm. The amount of talcum powder to be used is 2 kg per cubic metre of the test chamber volume. The duration of the test is 8 hours. • Immersion protected type (IP67) The lowest point of enclosures should be least 1,000 mm below the surface of the water. The duration of the test is 30 minutes.
