Custom panel potentiometers

TT electronics BI Technologies has developed custom panel potentiometers for XP Audio's Bolt guitar amplifiers. Using designs based on the Model P260 and Model P09x panel potentiometers, BI is supplying more than 30 potentiometers to the front and back of XP Audio's amplification systems.

"XP Audio's Bolt amplifiers provide high visual quality, and as the immediate human interface, our potentiometers must also follow suit," said Alain Leon, product marketing manager for BI Technologies. "With conductive plastic elements, concentric shafts and life cycles as high as one million rotations, the potentiometers suit amplifier and other pro audio applications."

In addition to amplifiers, BI's panel potentiometers are also being deployed in foot pedal, guitar and pre-amplifier applications.

BI Technologies developed custom package sizes and configurations to meet specific XP Audio application requirements with designs based on its standard Model P260 and Model P09x panel potentiometers. The standard Model P260 devices are IP66-sealed and offered in side- or top-adjust versions with PCB leads and a rotary switch option. Standard resistance ranges from 2K次 to 1M次, with standard tolerance to ㊣10 percent and a switch contact resistance of 150m次. Maximum rotational torque is 1.5oz-in (0.5oz-in each additional gang) and minimum switch detent is 2.0oz-in. Rotational life is to 1,000,000 cycles, with an operating temperature range from -55∼C to +125∼C.

Standard Model P09x rotary potentiometers are offered in side- or top-adjust switch versions with PCB pins and up to 8 gangs. Resistance ranges from 1K次 to 500K次, with standard tolerance to ㊣20 percent and a switch contact resistance of less than 100m次. Rotational torque ranges from 0.5oz-in to 1.25oz-in. Rotational life is to 100,000 cycles, with an operating temperature range from -10∼C to +70∼C.

Typical pricing for standard Model P09x and Model P260 panel potentiometers ranges from $0.30 to $2.00 in quantities of 1,000 to 5,000 pieces. Lead time is four weeks.
