New 6 mm Potentiometer for High Temperature Lead-free SMD Production

Piher Sensing Systems has re-designed its popular PT-6 Carbon Potentiometer for high temperature lead-free SMD production.

High-temperature plastics, flat suction areas for vacuum pipettes optimum assembly and a new pad design enables PIHER’s customers to employ automated placement of this components on their circuit board using reflow solder and thus simplify their manufacturing processes.

A wide range of options, including the unique stop positions (detents) that provide users desirable tactile feedback on each position setting and selection. Detents not only add a crisp “click” sensation for each position but also offer significant savings in both cost and space; and are particularly advantageous in industrial, home automation and domestic power tool applications to prevent accidental movement.

“The detent feature for 6mm potentiometer lines is a complete market breakthrough, says Jose Luis Macía, Commercial Director. “With the re-engineered 6mm potentiometers, PIHER now provides a reliable rotary ‘click’ sensation into its smallest line of rotary controls on both standard mounting versions (through hole and SMD).”

The new detents, which include as standard up to 10 equally spaced positions, have a spring feature that is incorporated into the product’s rotary action. This creates a resistance to rotation at predetermined angles that gives the user a ‘click’ action, alerting of the current position of the control. For maximum design versatility, the detents can be set at custom angles to suit specific requirements.

PIHER’S 6mm potentiometers, already popular in hundreds of white goods, motor control, power supply, appliance panel control, and automotive sensing applications, now offer product designers the full features of PIHER larger products in a miniature package.

The 6mm family features flame-retardant plastics (meets UL Standard 94 V0), a carbon resistive element, dust and waterproof enclosure (IP54). The new pot is supplied in reels for easy automatic insertion and is available with a variety of options including rotors, standard knob and shafts and long-life versions.
