DESCRIPTION

The 86A2A-B28-A15/R50 is a 5/8" square single-turn panel control potentiometer with integrated rotary switch functionality, designed for on-off control applications. It features a metal shaft and bushing with consistent, smooth quality feel, and is available in up to 4 sections for multi-channel configurations. The device incorporates a single plain 1/4" (6.35 mm) diameter shaft with a standard slot 1.19 mm wide and 1.60 ± 0.38 mm deep, paired with a "B" bushing (3/8" plain, 9.53 mm diameter × 1/2" length) for secure panel mounting. The potentiometer supports standard resistance ranges from 1 kO to 1 megohm with ±20% or ±10% tolerance depending on element type, and features ±5% independent linearity. This RoHS-compliant component is ideal for audio equipment, industrial control panels, and consumer electronics requiring reliable rotary switching and volume/parameter adjustment.
