FD21 Robot Controller Introduction

OTC DAIHEN robotic welding FD21 teach pendant

FD21 Teach Pendant

The FD21 Teach Pendant represents the newest thinking and design in robot controllers. The FD21 is designed for comfortable, extended use. It’s lighter than the FD11, offers an improved ergonomic grip, features an edgeless LCD display and includes raised tactile buttons. We’ve also eliminated end-of-life failures with a replaceable hook, quick-connects at both ends of the pendant cable and a spatter-resistant screen border.
