Linear PKAC-110 PowerKey AC Machinery Access Control System, UL Listed, 99-Users, 110V

Protect operators and equipment by restricting power to machinery until an authorized code is entered. The Linear PowerKey AC access control keypad is a UL Listed, 110V access control system designed specifically for industrial and manufacturing environments where safety and accountability matter. With capacity for 99 unique users, the PowerKey AC lets facilities assign individual or shared codes, log operator transitions, and minimize unauthorized use.

Beyond simple keypad control, the unit senses load reduction to time out and requires reauthorization, and it monitors for overloads—automatically shutting down and alerting with diagnostic LED flashes. Capable of switching motors up to 1.5 HP and detecting loads from 50 mA and up, this controller integrates easily with broader security, monitoring, and access control strategies to support compliance and incident prevention.

Choose Linear’s PowerKey AC to streamline machine access, enhance workplace safety, and strengthen your security and surveillance posture. Contact sales to specify for your machinery or add the PowerKey AC to your next equipment order.
