LASER photoelectric switches in SICK ’s new family, the W 9L, have small housings, long ranges, high switching frequencies and are user-friendly.
No supplementary protective or safety measures are necessary thanks to the switches laser protection class 2. With CE, UL and CDRH approvals these sensors are suitable for use in automation technology.
The W 9L family includes the adjustable WT 9L photoelectric proximity switch with background suppression, the WL 9L photoelectric reflex switch with teach-in and optional polarisation filter, and the WS/WE 9L through-beam photoelectric switch, that can also be set up using the teach-in button on the device itself.
All sensors share an enclosure rating of IP67, the robust ABS housing, and the pulsed laser transmitter. This generates a light spot that is less than 0.5mm in size, allowing even the smallest objects to be reliably detected even at a switching frequency of 1kHz.
The temperature-compensated laser protection electronics ensure that protection class 2 is reliably maintained under all operating conditions. The devices have µC technology that provides a number of options allowing customer requirements to be met.
The reading distance of the WT 9L is 150mm, the WL 9L offers a range of 12m, and the WS/WE 9L through-beam system is suitable for up to 50m.
The photoelectric switch function is not effected by external light sources such as flash-lights or strong interfering radiation from devices such as mobile telephones.
Simple teach-in, operating and reception indicators on the device, and a range of accessories ensures user-friendliness during mounting and commissioning.
The KT3 contrast scanner, the CSM colour sensor and the Lut-2 luminescence scanner are also available from SICK, all in the same housing as the W 9L.
