StoneL QX2VB02SNM Quartz Limit Switch

StoneL QX2VB02SNM Quartz Limit Switch is a Quartz-series valve-position indicator designed to provide reliable feedback of valve status in automated process lines. The device belongs to StoneL’s Quartz family, featuring an epoxy-coated anodized aluminum housing for corrosion resistance and durability in washdown environments, and it mounts flush to actuators using standard VDI/VDE 3845 patterns for quick, tool-free installation. The QX/QN platform supports multiple switch types—solid-state, magnetic reed proximity, or mechanical contacts—allowing configuration to match your control scheme, and it offers a quick-set cam system that simplifies setup without tools. On the electrical side, Quartz limit switches in this family use universal voltage ranges suitable for AC or DC applications and provide status indicators via bright LEDs for easy process visibility. The QX2VB02SNM is part of the broader Quartz line that Valmet describes as offering diverse configurations including explosionproof (QX) and general-purpose (QG) options to fit demanding environments. A useful lifetime for Quartz QX/QN models is cited at approximately 12 years in standard valve-position applications, making this switch a long-term option for reliable valve control, safety interlocks, and precise process feedback.
