Lumberg panel mount barrel jack with solder lugs.This DC jack features a normally closed switch on the ring (sleeve) connection. For use with barrel plugs with a 5.5mm external diameter and 2.1mm internal diameter. Mounting nut included.

OP07 precision op amp in an 8-pin DIP package.These devices offer low offset and long-term stability by means of a low-noise, chopperless, bipolar-input-transistor amplifier circuit. For most applications, external components are not required for offset nulling and frequency compensation. The true differential input, with a wide input-voltage range and outstanding common-mode rejection, provides maximum flexibility and performance in high-noise environments and in noninverting applications. Low bias currents and extremely high input impedance are maintained over the entire temperature range.

• Round Pin
• 20 Position
• 2.54mm Spacing
• Breakaway
