Functional safety (and IIoT connectivity) from linear brakes
In a recent Design World feature, we covered the basics of how functional safety is quantified … and what constitutes a servo-brake option with functional-safety certification. Here we share more details on the construction of safety brakes for linear axes and the intersection of brake safety and IIoT capabilities. Machine safety is core to nearly […]
More about what it means for servo brakes to have functional-safety certification
In the article What are functional safety standards for servo drives? we review how functional safety is quantified. Now consider one example of a spring-set pneumatically released friction servomotor brake now having a third-party safety rating (from Intertek Group) certifying compliance with international safety standard ISO 13849-1. Intertek is an international London-headquartered inspection, assurance, product […]
Inductive proximity and magneto resistive sensors enhance IoT4.0 connectivity for Nexen brake families
Nexen Group, Nexen Servo, Rail, and ZSE brake lines now have Industry 4.0 connectivity sensor options to enhance machine efficiency.
