DESCRIPTION
The 66156 contains a Gallium Aluminum Arsenide (GaAIAs) infrared LED optically coupled to a silicon photodiode. This
66156-20X is a hermetically sealed package which is threaded in order to provide convenient bulkhead mounting and is
available in standard and screened versions or tested to customer specifications. The 66156-10X is a hermetically sealed
coaxial package which can be soldered or press-fit mounted and is also available in the same versions.
