A photoelectric switch includes first and second shell halves respectively having first and second coupled surfaces which confront each other along an axis in either a horizontal direction or an upright direction. The coupled surfaces respectively have first and second recessed regions aligned with each other to confine a rolling chamber for a roller to be rollable therein, and define left and right holes at two opposite ends of the rolling chamber, and emitter and receiver accommodating chambers outwardly of the left and right holes for accommodating a light emitter and a light receiver such that a light passage is defined by the left and right holes and the rolling chamber.

The present system provides a sensor clip system that can be clipped to luminaires of a plurality of shapes and sizes and method of using the sensor clip. Some of the sensors are upward looking (into the luminaire) while others are downward looking (away from the luminaire); and thus face in substantially opposite directions. The sensor clip is adjustable in one, two or three dimensions to be able to easily fit with different sized and shaped luminaires, such that the upward looking sensors may face the incoming light and downward looking sensors face away from the light. The sensor clip system may also provide attenuation of the luminous intensity of the emitted light coming out of the luminaires and extends the longevity and usability of the embedded sensor.

An apparatus for suspending a sensor element is provided. The apparatus can include a housing including a cavity, an inner surface, and a first end cap integrally formed within a first end of the housing. The housing can include a sensor element therein. The first end cap can include a first plurality of suspension elements integrally formed within the first end cap and arranged to project from a surface of the first end cap toward the cavity. The inner surface of the housing and/or the first plurality of suspension elements can suspend the sensor element within the cavity as the sensor element translates within the cavity. Related systems and methods of manufacture are also described.

The present application discloses an apparatus and method configured to measure characteristics of high power beams of laser energy used in material processing. In one embodiment, the apparatus includes a housing having a first compartment and a second compartment separated from each other to reduce the transfer of thermal energy between them. Optical modules having optical sensors configured to measure characteristics of the high power beam are mounted in the first compartment. A removable and replaceable beam dump configured to absorb most of the high power beam is positioned in the second compartment. The removability/replaceability of the beam dump enables operation of the apparatus without active cooling of the beam dump assembly, simplifying the apparatus and protecting the optical sensors in the first compartment.
