Two-Hand Control Monitoring
 | Two-Hand Control Monitoring Safety Relays detect faults in two-hand controls, wiring, and contactors safety circuits. These relays provide switching action as an intermediate relay. They are designed for use with mechanical and capacitive two-hand control units. |
Muting Light Curtain Monitoring
 | Muting Light Curtain Monitoring Relays automatically let a valid load or object pass through the light curtain in either direction without shutting down the machine. |
Stop Motion Monitors
 | Stop Motion Monitors detect when hazardous motion has ceased, then sends a signal to unlock guard-locking devices. |
Speed Monitors
 | Speed Monitors are designed for motion applications that require interaction by personnel during operation. |
Back EMF Monitors
 | Back Electro-magnetic Field (EMF) monitoring units interface with single- or three-phase induction motors to measure the drive voltage and the back EMF of the motor. |
Mat Controllers
 | The MatGuardTM Control Unit monitors all of the mats that are connected together to form a safeguarded zone. The safeguarded zone can be up to a total of 100 m2 and made from any number of mats. The controller interfaces with the control circuit of the machine and includes two safety relays to help provide control redundancy. |
440F MatGuard Mat Manager
 | The MatGuard™ Mat Manager monitors multiple safety mats, each with its own connection. It accepts up to eight individual mats with four-pin micro quick disconnect connectors. The Mat Manager has indicators for each of the mat connections that show whether the mat is shorted or open. As a result, troubleshooting and replacement of a damaged mat within a mat system is quicker than in a traditional mat system where multiple mats are wired in series. |
440F Safedge Controllers
 | The Safedge™ Controllers operate with the Safedge Safety Edge Profiles. The controllers continuously monitor the profile for actuation and generate an output signal when the profile is depressed. |
Sipha Control Units
 | Sipha Control Units incorporate several magnetically sensitive elements that must be triggered in a particular sequence to operate correctly. The Sipha sensor, designed to operate with its own actuator, helps prevent defeatability by a simple magnet. |
