In-Line Device and Signal Protection

Suppressors, Filters & Isolators

In-line suppressors, filters, and isolators are small, plug-in accessories designed to connect directly to a sensor, indicator, or other device. They fit seamlessly into your factory applications and begin operating immediately to suppress or filter electrical noise and transients.

  • Inline noise and transient control reduces electrical interference, which protects connected devices and prevents false triggering and intermittent faults 
  • Rugged overmolded design meets IP65, IP67, and IP68 standards 
  • Simple M12 quick-disconnect connection for easy installation where needed in the circuit 
  • Improve signal integrity and reduce troubleshooting time, and install wiring more quickly 
  • S25GI Galvanic Isolator eliminates ground loops and electrical faults while maintaining reliable Modbus® RTU/RS-485 communication in noisy environments by fully isolating communication and power between network segments and blocking surges, EMI, ESD, and voltage offsets without degrading signal quality
