EMX Industries 4012-2 Wireless Edge Link Kit
The EMX Industries 4012-2 Wireless Edge Link Kit (WEL-200K) delivers a complete wireless safety edge interface solution with an operating range of up to 200 ft. at 915 MHz, UL325-2018 compliant, and Made in USA.
Overview
The EMX Industries 4012-2 Wireless Edge Link Kit (WEL-200K) provides a complete wireless solution for interfacing sensing edges with gate and door operators. By eliminating the wiring between the safety edge and the operator control box, the system ensures compliance with UL325-2018 monitoring standards. The receiver supports up to four safety edge transmitters and provides separate relay and pulse outputs for open and close edge functionality.
