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. Multiple sensors integrated into the brake families provide information about brake operation and health to the control system network. The sensors used in the spring-operated air-released ZSE brakes provide operation information such as brake engagement […]
Podcast: Dave Hein of Nexen Group on brakes having functional safety certification
In our most recent Technology Tuesdays podcast, Dave Hein — senior vice president and engineering and chief technology officer at Nexen Group — chatted with us about three brake options that now have Functional Safety certification. Listen in: Design World · Brakes with Functional Safety certification: Update from Nexen Group engineer Dave Hein According […]
New zero-backlash, spring-engaged brake family
Nexen Group Inc. has announced the Zero-Backlash Spring Engaged (ZSE) brake family. The pneumatically-released ZSE offers high torque, high speed, and zero backlash ideal for holding applications. Unlike brakes using leaf springs to transmit torque, the ZSE is zero-backlash up to 100% of its rated holding torque. Nexen has released four different sizes (450, 600, […]
