SERIES 37F CUSTOM PIEZO K E Y PA D S AND PUSHBUTTONS V A N D A L R V I R T U A L LY E S I S T A N T I A N D N D E S T R U C T A B L E Function Section View Advantages Technology The switch function is based on the the physical principal of the Piezo effect. The external push force (increase or decrease) activates a Piezo element that releases voltage utilized for switching (MosFet). We offer three switching functions: • Pulse - 120 Msec. Pulse Typical • Momentary - Circuit closed as long as switch is pressed (requires external power) max 30 sec • Toggle - Switch changes position at each activation (requires external power) • Suitable for harsh environments • Sealed metal surface, epoxy potted • Pressure activated, no moving parts • Versatile mechanical configuration - Water and dust proof - indoor and outdoor use (IP68 Degree of Protection) - Virtually Indestructible, vandal proof, easy to keep clean - Long life expectancy, tested for 50 million cycles - Manufactured in any shape Applications Te c h n i c a l D a t a • • • • • Vending machines Lifts Beverage dispensers Food industry Mining equipment • • • • • Public internet and information kiosks Chemical and petrochemical industry Safety and security Medical equipment Industrial machinery Rated Voltage: Rated Current: 24 V ac or Vdc 200 mA Max 1A if requested Switch Resistance “ON”: Switch Resistance “OFF”: Switch Capacitance: Actuation Force (Typical): Operating Temperature: 10 ohms Max > 5 Megohms 25 pF 3-5N -20˚C to +75˚C, -40˚C to +125˚C if requested (according to customer request) Circuit Diagram PIEZO Cycles: EMI or RFI Effect: Degree of Protection: LED: OUT >50 million none IP68 per IEC 529 5 V dc, Imax 10 mA Environmental High Temperature (Operational) Low Temperature (Operational) Rain Sand And Dust MIL MIL MIL MIL STD STD STD STD 810 810 810 810 C C C C Temperature shock Mechanical shock MIL STD 202 E MIL STD 202 E High Temperature (Storage) Low Temperature (Storage) Humidity Water MIL MIL MIL MIL STD STD STD STD 810 810 810 810 C C C C Vibration Salt fog MIL STD 202 E MIL STD 202 E Custom Keypads Our custom made keypads range from minimal solutions of 2 keys per keypad to large keypads in various colors, designs and sizes.
