Frequently Asked Questions
What's the difference between limit switches and proximity sensors?
Limit switches: Mechanical operation (physical contact), higher force required, audible/tactile feedback, lower cost, works with any material. Ideal for: positive position verification, high-force applications, cost-sensitive designs. Proximity sensors: Non-contact operation (electromagnetic/capacitive), no wear, faster response, higher cost. Ideal for: high-cycle applications, fragile objects, dirty environments. Choose limit switches for positive verification and low cost; choose proximity for high speed and no wear.
What does IP67 rating mean for switches?
IP67 rating: 6 = Dust-tight (complete protection), 7 = Protected against temporary immersion (15cm to 1m for 30 minutes). Suitable for: outdoor use (with proper enclosure), washdown areas (not high-pressure), dirty/dusty environments. For high-pressure washdown (food processing), look for IP69K rating. For indoor clean environments, IP64 (splash-proof) may suffice. Always match IP rating to your environment. Higher IP rating = better protection but higher cost.
How do I wire a limit switch with NO and NC contacts?
Most limit switches have SPDT (1NO + 1NC) contacts: For position detection: Use NO contact (closes when actuated). For safety interlock: Use NC contact (opens when actuated - fail-safe). Wiring: Common terminal (C) to power/signal, NO to load for position detection, NC to load for safety. For safety circuits, always wire NC contact in series with safety relay. Verify contact operation with multimeter before connecting to control system.
