SICK has introduced the WLL 190, a new series of space-saving fibre optic photoelectric switches.

These new devices have bus-enabled hardware, interactive control panel and integrated monitoring of performance.

All devices can be identically pre-adjusted during the production process. During operation, the WLL 190 has stable and reliable switching behaviour even at high-resolution switching thresholds.

The bus-enabled hardware of the WLL 190 cuts wiring costs and also offers up to eight times better immunity than other systems. The MLL 190 also provides the possibility of balancing two measured values.

The interactive control panel, consisting of a three- and a four-character display, simplifies teach-in programming of switching thresholds, response time and off-delay, and offers a variety of opportunities for displaying stored and current values.

The integrated monitoring of performance ensures constant switching thresholds and compensation for ageing effects, temperature and voltage fluctuations. The WLL 190 range has been increased by a factor of three compared with the previous series, providing more possibilities for operation.

The WLL 190, to which fibre-optic cables of the LL3 series from SICK are connected, is available as a through-beam photoelectric switch with a range of 1300mm and a photoelectric proximity switch with a range of 300mm.

A red light LED serves as the transmitter for both the WLL 190 and the LL3 series cables. In conjunction with a green light LED, the proximity switch can be used as a mark sensor for detecting printed marks.

One or two independent switching points, the balancing of two switching points, switching within a range defined by two values, and glass detection, can be programmed during teach-in of the switching thresholds.

The WLL 190 is supplied pre-set to standardised values during production. Thus all devices leave the works with identical sensitivity, switching output, timing stages, and hysteresis settings.
