Profile: D & R Technology, LLC deals with custom designed sensors and switches & electromechanical assemblies. Our services include high volume automated assembly, low volume lean assembly cells, in-house overmolding, proprietary high speed encapsulation, soldering and crimping, magnetization, torque monitoring, ultrasonic welding, and mechanical assembly. Non-contact sensors offer the variable output needed by control systems, while eliminating the electrical noise, vibration and wear that are a byproduct of physical contact between a sensor and its target. Non-contact switches are a source for a binary output (on/off, or yes/no), with the added advantage of eliminating the wear, electrical noise and vibration created by physical contact between a sensor and its target.
