2086 Series PCB terminal blocks for panel feed-through and tight spaces feature Push-In Cage Clamp spring-pressure connection for inserting solid and ferruled conductors, with the added convenience of pushbutton operation. The series has more than 256 variants, and lets users choose between pin spacing (3.5 or 5 mm), side or top wire entry angle, double inline or staggered pinning for higher voltages with nominal current, as well as through-hole or surface mounting. 2086s are available with two to 12 poles, accepting 24-14 AWG wire sizes.
