HW 22mm Heavy-Duty
Safety and ease of use were of paramount concern in the development of this line of switches, as evidenced by the simple mounting procedure, mechanically keyed safety lever lock (to prevent contact separation in heavy vibration applications), and wide variety of Emergency Stop models (all of which meet EN418).
Unique to the HW series is the HW Unibody E-Stop, which features one piece construction that prevents tampering or incorrect mounting from hindering the functionality of the switch. Another first is the spring loaded captive screw terminals, which make ring terminal wiring easier than ever before.
Key Features:
Terminal Style: Push-in terminal
First in the industry Six different colors with a single LED
Previously, 5 different color LEDs were required but with the new illuminated LED unit, only a single LED is used.
Only the lens needs to be replaced to change the illumination color.
The new LED reduces maintenance time, makes stock control easier, and is environmentally friendly.
High visibility with new LED
Brighter and clearer compared to conventional LEDS
ISO3864-4 Safety color compliant
Safety colors are defined with ISO standards.
The bright and clears colors are suited for emergency situations
*Except for products below
•Illuminated selector switches (illumination color: S (Blue), PW (Pure white))
•Illuminated pushbuttons (illumination color: S (Blue))
Simple wiring for greater work efficiency
Ferrules and solid wires can be connected simply by push-in insertion, without a screwdriver. (*1)
To remove, a flat-blade screwdriver is inserted in a simple two-action process.
Since wiring can be performed regardless of operators' skill level, wiring time is reduced.
*1) When connecting stranded wire, insert the wire while holding down the pusher
with a flat-blade screwdriver.
Time saving and efficient
Push-in connections are made simple by inserting the wire, reducing wiring time by approximately 55% compared to conventional screw terminals.
[Conditions]
Push-in: Insert wire with ferrule.
Screw terminals: With screw loosened, insert wire, then tighten with electric driver.
Reliable and easy
Finger-safe structure and vibration resistance.
What’s more, the space-saving design means better workability in a smaller space.
Stays firmly in place
Since the ferrule is held in place by a spring load, the wiring remains taut and vibration resistance is improved.
Finger-safe structure
IP20 Finger-safe protection enables wiring to be performed without direct contact between screwdriver and conductive part.
Wiring procedure comparison
Work can be performed without using tools and regardless of operators' skill level.
*1) When ferrule is used.
No additional tightening needed
Because screws are not used on push-in terminals, re-tightening of screws is not required.
Space-Saving
Contact block depth reduced
Saves space inside panel and enables
downsizing of equipment.
Smart
High-voltage pilot lights
No transformer required
Applicable for a wide range of voltage (100/120V AC/DC, 200/240V AC).
Mounts directly on control and power panels without transformers.
Ideal for use in Europe and north America for applications requiring high voltage.
Locking lever
Usability improved by easy mounting and removal.
The mounting status of the contact blocks can be confirmed at a glance from the back of the switch.
4-contact configuration available
with double contact blocks
Double contact blocks available for all models including emergency stop switches,
selector switches, key selector switches.
High voltage LED illuminated unit for illuminated pushbuttons
100/120V AC/DC, 200/220V AC, 230/240V AC types available. No transformers required and same depth behind the panel for for all illuminated voltages.
High voltage models do not require transformers enabling downsizing of equipment and panels.
1-contact types also available.
Angled connections
Angled connections make wiring easy even when switches are mounted on a panel.
Also, 24-degree inclination faced to the panel improves the fit of the wires, and contributes to downsizing of the panel and equipment.
Added Value
Our aim is to create products that enable customers to experience the utmost usability.
Test point
A test point is available to check connectivity of the wiring.
Check the connectivity easily using a tester.
Sub-Assembled Units
Sub-assembled units can be ordered for flexible use, such as sudden changes in design.
Terminal Style: Screw terminal
Universal Contact Blocks
• Self-cleaning rolling action contacts.
• Degree of protection: IP65 (except dual pushbutton: IP40)
• Dual pushbutton switches available with two pushbuttons and a pilot light integrated into one space-saving unit.
• A wide range of operating voltages for worldwide application.
Captive spring-up terminals
Wiring is easy with IDEC’s unique captive spring-up terminal that prevents screws from falling.
Two-way wire entry points
Wiring is possible from two directions.
Various crimp teminals, including ring or fork terminals, can be used.
