Micro Spring (per 5mm) 0.25mm wire

KRL micro springs are the smallest nitinol springs--and the lightest actuators available anywhere!  So, if you're looking to build something small, KRL is the place to go!

Spring mandrel size (spring inner diameter) equal and smaller than 3.2mm is defined as Microspring.  Available mandrel sizes are 0.5mm, 0.9mm, 1.15mm, 1.6mm, 2.4mm, 3.2mm.


The listing price is for per 5mm. If multiple units are ordered, a continuous length will be sent out unless said otherwise in the comments box.
