Z-15GW2S55-B7-K Omron

General-purpose Basic Switch Z CSM Z DS E 4 4 Best-selling Basic Switch Boasting High Precision and Wide Variety A large switching capacity of 15 A with high repeat accuracy. A wide range of variations in contact form for your selection: basic, split-contact, maintained-contact, and adjustable contact gap types. A series of standard models for micro loads is available. A series of molded terminal-type models incorporating safety terminal protective cover is available. Be sure to read Safety Precautions on page 26 and Safety Precautions for All Basic Switches. For the most recent information on models that have been certified for safety standards, refer to your OMRON website. Model Number Structure Configuration Refer to page 3. Basic models General-purpose Refer to page 5. Drip-proof Without terminal protective cover Refer to page 5. With terminal protective cover Refer to page 2. Molded terminal Refer to page 4. Split-contact models General-purpose Refer to page 4. Maintained-contact models General-purpose Basic Models Split-contact Models This type is identical in construction to the general-purpose basic General-purpose switch except that it has two pairs of simultaneous acting contacts A variety of actuators is available for a wide range of application. by splitting moving contacts. The contact mechanism of models for micro loads is a crossbar Since the moving contacts are connected to a common terminal, type with gold-alloy contacts, which ensures highly reliable either parallel or series connection is possible. operations for micro loads. Highly reliable micro load switching is ensured if the model is used Contact Gap: as a twin-contact switch. H2: 0.20 mm (extra-high-sensitivity) H: 0.25 mm (high-sensitivity, micro voltage current load) Maintained-contact Models G: 0.5 mm (standard) E: 1.8 mm (high-capacity) The maintained-contact type has a reset button at the bottom of the switch case, in addition to the pushbutton (plunger) located on the Drip-proof opposite side of the reset button. Use these buttons alternately. Since the Switch has greater pretravel than overtravel, it is suitable These Switches use a rubber boot on the actuator and adhesive fill for use in reversible control circuits, manual reset circuits, safety between the case and cover to increase resistance to drips. limit circuits, and other circuits which are not preferable for Models with drip-proof terminal protective covers and molded automatic resetting.
