MiniTwin safety light curtain

The miniTwin safety light curtain has been designed for tasks in which a machine's risk analysis demands the greatest possible level of protection - Performance Level pl e according to EN ISO 13849-1, or SIL3 in compliance with IEC 61508 or the sector standard EN 62061.

It offers a range of 0-4 m with resolutions of 14, 24 and 34 mm - also in corner applications. The high resolution and rapid response times of the miniTwin permit short safety distances, when necessary, for optimised work ergonomics.

Protective field heights that can be achieved range from 120-1200 mm. The housing size increments of 60 mm offer optimum adaptation of the protective fields to the particular machine conditions.

The miniTwin light curtain contains the transmitter and receiver elements in identical twin-sticks, symmetrically arranged in one housing, half each, and separated by a central synchronisation beam. Connection to the controller takes place via a 5-pin M12 plug. The identical nature of the transmitter and receiver, as well as that of the host and guest devices, offers reduced spare parts and design costs.

Configuration takes place during the power-up cycle, following electrical connection - automatically in the case of EDM, and by pressing a button for reset. The continuous row of LED indicators along the entire length of the device serves as an alignment aid, status indicator and diagnostic tool, and provides visual user-friendly delineation of the protective field on both sides of the sensor pair.
