FAQ
Frequently Asked Questions
Get answers to common questions about BL Series switches
What applications are BL Series switches best suited for?
The BL Series excels in medium-duty industrial environments – heavy machinery, conveyors, valves, pumps, and more. They’re ideal for manufacturing and process control applications (like production lines, fluid systems, and outdoor equipment) where durable position feedback is needed
What contact configurations are available?
BL Series switches are offered with 1NO+1NC (SPDT) or 2NO+2NC (DPDT) snap-action contacts. Both configurations use silver-alloy contact points for superior conductivity and long electrical life.
How durable are these switches in harsh conditions?
Extremely durable. They feature a die-cast metal housing with an IP67 rating (fully dust- and water-tight). Nitrile rubber seals and robust construction let them resist oil, moisture, and shock in demanding settings
Can BL Series switches be used outdoors or in washdown areas?
Yes. Their IP67-rated die-cast enclosure and high-quality seals make them suitable for outdoor and washdown applications. They withstand rain, dust, and spray, ensuring reliable operation in outdoor industrial installations.
What ensures long-term reliability of BL Series switches?
Several factors: the sturdy die-cast enclosure, precision snap-action mechanism, and premium materials. Silver-alloy contacts reduce wear and ensure consistent signals; nitrile seals and metal housing protect against contaminants and impact. These features provide years of maintenance-free service in industrial use.
