By Tolerance Labs engineering team. Specs from the makers’ published data.
5 models: 120–250 N force, 5–30 mm stroke, 0.09–0.16 kg weight, 12 V supply voltage. Every model is below with its key specs and US price.
BLA servos use a brushless motor, in inline (BLAC) and side-motor (BLAS) layouts, with force-sensing versions of each.
