Overview The robust ABS plastic housing in which all operating elements are protected is an essential feature of the W34 series. This makes it possible to also use these sensors outdoors. It is especially recommended to use the die-cast zinc housing (W24-2 series) for harsh and extreme ambient conditions The sensors are equipped with a minimum of different functions in order to reduce the diversity of the devices and, thus, their storage. In addition, both DC and DC / AC devices are offered in this form. The W34 series includes photoelectric sensors with background suppression, reflex barriers and single-beam systems. Photoelectric sensors are characterized by high accuracy at a great distance and high insensitivity to stray light. At a glance Rugged plastic or die-cast zinc housing (W24-2) The operating elements are protected by a cover High insensitivity to stray light and no interference due to face-to-face mounting of photoelectric sensors NPN / PNP switch Light / dark switch Models for 10 to 30 V DC or 12 to 240 V DC / 24 to 240 V AC power supply Optional: test input, time scales and contamination message M12 connector or M16 screw connection, each rotatable by 90 ° UL approval Your Benefit Very good resistance to chemicals prolongs service life The operating elements under the "hood" offer flexibility as well as the best protection in the application and reduce the diversity of devices and therefore storage. Safe operation in the event of parasitic light and opposite mounting of devices Best availability thanks to the very large functional reserve for reflex and single-beam barriers Mounting compatibility, as DC and DC / AC devices are available in the same form Note Product details cover the whole product family.
