DEUTSCH Diodes and Resistors in both directions. Resistors protect sensitive electronics by limiting the amount of electricity that can flow to the device through the resistor, and therefore preventing power spikes. For example, resistors are used to prevent power surges from burning out an LED by restricting current flow to the light. DEUTSCH industrial diode and resistor connectors are easily added to an application after the fact if unwanted power surges are discovered.

Light Guides for Photoelectric Control For some types of sensing applications, fiber optic components are used to transmit and receive a light signal, carrying the signal back to a photo sensor, which in turn, actuates an electric control. The overall process senses and reacts to a difference in light intensity to confirm the absence/presence/position of an object. Fiber optic components protect photoelectric sensors (from heat and harsh environments) and facilitates their use in space-restrictive areas. They may also be used...
