Dimensions
Installation time reduced by 90%
No more screwing needed
Two terminals each for simple
through-wiring
Long service life
Rubber seal to protect switching
contacts
High-quality material combinations
Innovative bell button with reliable precious metal switching
contacts and time-saving wiring technology for installation in
door stations or for industrial use
Product features
Maximum reliability due to corrosion-free switching contacts
with a silver alloy incl. gold-plating
Optimum switching behaviour due to tactile feedback and
precise button guidance in collar
Very low bounce times due to optimum switching contacts
snap effect; ideal for BUS intercom systems
Short installation time due to screwless special terminals;
ideally suitable for through-wiring
Suitable for plate thicknesses up to 6 mm despite extremely
compact design
Noble look due to high-quality materials and surfaces
Installation
Plate hole 16 mm (replacement-compatible with predecessor
models MKO/KKO), plate thickness 0.5 mm to 6.0 mm
Installation depth 13 mm minus plate thickness
(e.g. for 2 mm plate thickness, 11 mm installation depth)
Time-saving fitting without tools thanks to easy-to-grip
knurled nut
Technical data
Max. 24V=/~ (1.5A); min. 5V (1mA)
Voltage drop in new condition 0.1V; contact resistance 0.1Ohm
Innovative illumination technology
LED module for direct connection to
8/12V~
No more replacing of bulbs
Insulation resistance: Min. 100 MOhm
Bounce time < 20 ms
Suitable for rigid wires with diameter 0.6 mm to 0.8 mm
Actuating force approx. 6 Newton
Contact travel 0.8 mm / Total actuating travel 1.2 mm
-20°C to +60°C
IP 54 (when installed, vertical plate)
Protection against vandalism through compressive force
limitation (withstands min. 100 N actuating force)
Materials: switching contacts made of chrome-nickel steel
with silver alloy and gold-plating; housing made of glassfibre
reinforced ABS for optimum stability; special terminals
made of tin-plated chrome-nickel steel; for button/button
collar, see ordering overview
Installation position: any (see note at "IP54")
Min.service life at 12V~ / 0.75A (standard bell system)
approx. 100,000 cycles (note: tactile switching behaviour
up to approx. 30,000 cycles, thereafter constant switching
behaviour until the mechanical service life of 250,000 cycles,
corresponds to a service life of 8 years when actuated
10 times daily).
Note
At higher currents the gold surface of the switching contacts
disintegrates for physical reasons. This is not indicative of
poor quality, rather just means that the bell button can subsequently
no longer be used for small currents in the mA range.
