· Directionality of the switch unit is eliminated to facilitate assembly
[Miniaturization]
· The wiring direction is changed so lateral space is not required (Push-in Plus terminal block type)
· Short Body Design
[Safety]
· It uses a lock lever mechanism that can be reliably and easily operated
· The finger protective structure provides high safety
· The wiring will not loosen and is therefore maintenance-free (Push-in Plus terminal block type)
[Product Lineup]
· Safety standard / voltage specification as a global product
· Can be installed on two panel processing dimensions of φ22.3 and φ25.5
· The buttons and bezels are available in abundant colors, shapes and materials
· Conforms to IP66 and NEMA 4X/13 for protective structure

(2) Ambient humidity: 65±5%RH
(3) Operation frequency: 30 times/min
*2. Minimum applicable load
5 V DC, 6 mA resistant load
The usable area may vary depending on the usage conditions and the type of load.
* The minimum applicable load is the N level reference value. This is expressed as the level of failure level at a confidence level of 60% (λ60). (JIS C 5003)
λ60 = 0.5 × 10^-6 / time means that a failure level of 1/2,000,000 or less is estimated at a confidence level of 60%.

  • * Except for the above number of connections, check the actual machine under actual usage conditions, and use it with the number of times of switching that will not cause a problem in performance.
  • * □: Switch unit／■: Lighting unit

Important Points

  • * Do not perform wiring work with the product powered. Do not touch live parts such as terminals while the power is on. Doing so can lead to electric shock.
  • * Do not disassemble or modify the product under any circumstances as it may impair normal operation.
  • * The product functions may not be fully exerted. Do not drop the product. Also, do not apply force that causes deformation or deterioration of the product.
  • * The durability of the switch greatly depends on the switching conditions. Before using the product, be sure to check the actual device under the actual operating conditions and use it within the number of switching operations that will not cause a performance problem.
  • * Keep the load voltage and current below the rated value. It may be damaged or burnt out.
  • * Do not use in an atmosphere of flammable gas or explosive gas, or in a place exposed to flammable solvents. It may cause ignition or explosion due to the arc or heat generated from the switch when opening or closing.
  • * Do not use in an atmosphere of malignant gas such as sulfide gas (H_2S, SO_2), ammonia gas (NH_3), nitric acid gas (HNO_3), chlorine gas (Cl_2), or high temperature and high humidity. It may cause functional failure such as contact failure or damage due to corrosion.
  • * Do not use it in oil or water, or in an environment where it is constantly exposed to water or oil. Water or oil may get inside and cause a malfunction.
  • * Make sure there is a rubber washer installed between the control and the panel. It may not satisfy the protective structure.
  • * Do not apply excessive force to the switches or wiring. It may cause contact failure due to damage or deformation of the switch unit.
  • * Use the appropriate cable and ferrule terminal.
  • * Be careful not to miswire the terminal connections.
  • * Do not use or store in the following environments. Places where temperature changes drastically / places where high humidity may cause dew condensation / places that vibrate violently / places exposed to direct sunlight / places exposed to salt breeze.
  • *See the manufacturer's catalog for product information other than the above.
