An optical encoder comprises an emitter; a receiver; a reflector; and a code carrier, wherein the emitter emits electromagnetic radiation along an emission axis in the direction of the reflector and the reflector deflects the electromagnetic radiation along a reception axis in the direction of the receiver. The code carrier is movably supported and has a sequence of code sections to interrupt or to give way for the emitted electromagnetic radiation to impinge on the detector in dependence on the position of the code carrier, wherein the emission axis and the reception axis extend at an alignment angle with respect to one another that has a value in the range from 30 degrees to 150 degrees.

Optical encoder

An optoelectronic apparatus is provided having a carrier device that has at least one optoelectronic transmitter and/or at least one optoelectronic receiver at an upper side; at least one first optical element, a second optical element, and a third optical element that are arranged in a layer arrangement above the carrier device, with the second optical element being arranged above the first optical element and the third optical element being arranged above the second optical element, and with each of the at least three optical elements comprising a lens element, an aperture element or a filter element; and a holding device that holds at least the first optical element and the second optical element relative to the carrier device and partly surrounds them, with the holding device furthermore either holding the third optical element relative to the carrier device and partly surrounding the third optical element or forming the third optical element.

Optoelectronic apparatus, carrier device, optoelectronic transmitter and optoelectronic receiver

An optoelectronic apparatus is provided having a carrier device that has at least one optoelectronic transmitter and/or at least one optoelectronic receiver at an upper side; having a lens element that is provided above the carrier device and that has at least one lens section for the at least one optoelectronic transmitter and/or for the at least one optoelectronic receiver; and having a holding device that at least partly surrounds the carrier device and the lens element. The lens element has a mechanical coding section that projects out of the holding device and that enables at least one coding element for identifying the optoelectronic apparatus.

Optoelectronic apparatus having a coding element

An optoelectronic apparatus is provided, comprising a carrier device that has a longitudinal extent and a transverse extent, wherein the carrier device has a plurality of electrically conductive tracks aligned in parallel with the longitudinal extent, and wherein the carrier device has a plurality of contact chambers aligned in parallel with the transverse extent at an upper side. Each of the contact tracks is electrically contactable in each contact chamber to be able to install at least one optoelectronic transmitter and/or at least one optoelectronic receiver in a variable mounting in the respective chamber.

Optoelectronic apparatus

An optoelectronic apparatus is provided that has at least one optoelectronic transmitter and at least one optoelectronic receiver. The optoelectronic apparatus furthermore has a storage device having at least one non-volatile memory that is adapted to store an individual data set. A data interface is furthermore provided that is adapted to at least partly read the individual data set out of the non-volatile memory of the storage device.

A multi-terminal surface-mounted electronic device with contact surfaces placed entirely or partly around several sides, as well as to a method for manufacturing it. The parts according to the invention allow assembly on a circuit board such as p.c.b. and foil in forward, backward and sideward direction. Previous multi-terminal surface-mounted electronic devices could as a rule be mounted in one direction only. For all other directions such as backwards and sidewards costly special constructions or fundamental changes to the circuit board (printed-circuit board, foil) were necessary. In accordance with the invention, an electronic component is located in a housing and both the electronic component and the housing are joined to a base strip. The base strip provides the terminals whose contact surfaces are so formed that they can embrace the entire housing either completely or partially.

Multi-terminal surface-mounted electronic device

A photo interrupter which features at least one transmission element and at least one receiver element separated by an optical transmission path. To ensure a flexible structure with variable characteristics, the photo interrupter features a modular structure comprised of two joinable housing parts. In order to reduce production costs and simplify the production process, the housing parts of the photo interrupter respectively feature one carrier unit each which is designed as a panel of a mounting strip, as well as at least one semiconductor device located on the carrier unit, and a housing body forming the two side surfaces of the photo interrupter, which housing body--in a first partial area of the carrier unit containing the semiconductor device(s)--encloses the carrier unit; at least one semiconductor device of the one housing part will be a transmission element, and at least one semiconductor device of the other housing part will be a receiver element. To enable easy assembly of the two housing parts, at least one of the two housing parts features a connecting part which is mounted on the housing body and forms the base area of the photo interrupter; this connecting part provides a flush joint for the two housing parts.
