NKK Switches Membrane Keypad FMBP16BF

The FMBP16BF is a 16-key illuminated membrane keypad with dot illumination at the upper left corner of each key, featuring an embossed white keypad with gray legends and a gray surface sheet. It has a 1.0mm tail pitch, adhesive backing for mounting, and a nominal operating force of 1.0N to 6.0N. The stroke is 0.5mm to 1.2mm, with an operating temperature range of -15°C to +50°C. The integrated single-element LED operates at 20mA typical forward current with a 2.1V forward voltage, and maximum forward current of 30mA. The keypad supports 1,000,000 operational life cycles, with contact resistance not exceeding 500Ω and insulation resistance of at least 100 megohms at 250V DC. A ballast resistor is required if the source voltage exceeds the LED rating. The part uses an 8-pin connector with a switch circuit matrix and a recommended FCI SLW8S-5C7LF straight connector.
