IMO Precision Controls has introduced a range of safety switches that are suitable for applications, such as pick-and-place or assembly machines, that require frequent operator manual intervention. There are four variants in the new FR family of switches, providing rope switch actuation, rotating head and lever switches for open guard sensing, and high-speed key entry switches that protect against damage caused by slamming guards. FR switches operate at up to 3,600 cycles/h and feature bifurcated gold-plated contacts for longer life and better signal transfer. They are available with PG13.5 or optional M20 conduit entry, an IP65 rated terminal chamber and eight contact block configurations.
