FMBN16BE

Membranes Series FM DISTINCTIVE CHARACTERISTICS Nonilluminated options in 4 or 16 keys, illuminated choices in 12 or 16 keys 1.0mm (.039) tail pitch Easily integrated into designs: replaces multiple mechanical switches, soldered wires and cable assemblies Card insertion into design supports customized legends for nonilluminated models Actuating dome offers crisp, tactile feedback to positively indicate circuit transfer Illuminated models feature legends on embossed keypads Adhesive backing for easy mounting GENERAL SPECIFICATIONS Power Level 20mA 24V DC Contact Resistance 500 maximum (10mA 10V DC) Insulation Resistance 100 megohms minimum 250V DC minimum Dielectric Strength 250V AC minimum for one minute minimum Operational Life 1,000,000 operations minimum Contact Timing 10 milliseconds maximum Nominal Operating Force 1.0N ~ 6.0N Stroke: Nonilluminated .016 ~ .039 (0.4mm ~ 1.0mm) Illuminated with Overlay .020 ~ .047 (0.5mm ~ 1.2mm) 15C ~ +50C (+5F ~ +122F) illuminated Operating Temperature Range 15C ~ +55C (+5F ~ +131F) nonilluminated LED SPECIFICATIONS Single Element LED Color: Amber Unit The electrical specifications E V F R I + F R = shown are determined at a Forward Voltage (Typical) V 2.1 V F I F Anode basic temperature of 25C. Where: R = Resistor Value (Ohms) Forward Current (Typical) I 20 mA E V F F LED is an integral part of E = Source Voltage (V) V = Forward Voltage (V) the switch. LEDs are not Cathode F Forward Current (Maximum) I 30 mA I = Forward Current (A) F F sold separately. * Forward Peak Current (Max) I 195 mA FM LED circuits are isolated and require an external power source. If the source voltage exceeds the rated voltage, a ballast resistor is required. Reverse Voltage (Maximum) V 5.0 V R * Note: Pulse width 0.1msec maximum with a maximum duty cycle ratio of 1/10 L Ordering Information Description Surface Sheet Part Number Illumination Number of Keys Overlay Black (D) Gray (E) FMBN04BD 4 FMBN04BE 4 Nonilluminated FMBN16BD 16 FMBN16BE 16 Dot Illuminated Gray Surface Sheet with FMBP12BF 12 with Embossed White Keypad FMBP16BF 16 Overlay and Gray Legends www.nkkswitches.com L39 6/15/18 Supplement Accessories Indicators Touch Tilt Tactiles Slides Rotaries Keylocks Programmable Illuminated PB Pushbuttons Rockers TogglesSeries FM Membranes TYPICAL SWITCH DIMENSIONS Nonilluminated 4 or 16 Keys Switch Circuit Matrix (9.0) Typ (6.0) .354 .236 For 4 Key (0.7) P (1.0) Typ .028 .039 1 (0.3) (0.3) P (1.0) Typ (18.0) (0.7) Typ (0.5)R Typ .012 .012 .039 .709 .028 .020 2 (0.5) R Typ (1) (8.0) .020 Pin 1 Pin 5 Pin 1 (8.0) .315 3 .315 (2) (4.0) Pin 8 (4.0) .157 4 .157 (70.0) (70.0) (3) 2.756 2.756 5 (4) Key numbers in parenthesis are not actually on panel 13 14 15 16 1 and are for reference only 9 10 11 12 2 Switch Circuit Matrix Detail For 4 or 16 Key (93.0) 3.661 7 8 3 5 6 3 4 4 1 2 Switch Circuit Matrix For 16 Key (1.2) Sq (93.0) .047 3.661 (1.2) 8 (36.0) .047 (13) (14) (15) (16) 1.417 7 (9) (10) (11) (12) 6 (5) (6) (7) (8) 5 FMBN16BD (1) (2) (3) (4) FMBN04BE Black 4 Gray Surface 3 Surface Sheet Sheet 2 1 Key numbers in parenthesis are not actually on panel and are for reference only Insertable Legend Card for 4 Key or 16 Key (1.0) (18.0) Sq Typ .039 .709 L (82.5) 3.248 Insertable Legend Cards (19.0) Typ (19.0) Typ are supplied with the .748 .748 nonilluminated switch keypad assembly in (12.75) Typ (12.75) Typ .502 .502 Black, Gray and Yellow (1.0) (12.75) Typ (19.0)Typ (18.0) Sq Typ .039 .502 .748 .709 (25.5) (0.1) (0.12) (82.5) Sq ~ 1.004 3.248 .004 .005 L40 www.nkkswitches.com Supplement Accessories Indicators Touch Tilt Tactiles Slides Rotaries Keylocks Programmable Illuminated PB Pushbuttons Rockers Toggles
