To order the 9 m (30 ft) cable models, add the suffix "W/30" to the cabled model number. (for example, QS18WE W/30) QD models: To order models with a 150 mm (6 in) pigtail cable with 4-pin AC Micro-style QD, add suffix “Q2” to (1) MOSFET: Metal oxide semiconductor field-effect transistor.

A model with a QD connector requires an accessory mating cordset. 600 V cable models: Standard models are supplied with 300 V cable. For 600 V cable, add suffix “C1” to the model number (for example, QS18WEC1). In light operate (LO) mode, the output is ON when the target returns the same or more light to the sensor and OFF when the sensor detects less light than the configured/taught target. In opposed and retroreflective sensing modes , light operate is active when the beam is unblocked. In diffuse, fixed field, and adjustable field sensor modes , light operate is active when the target is present. In dark operate (DO) mode, the output is ON when the target returns less light to the sensor than the configured target and OFF when the sensor detects more light than the configured/taught target. In opposed and retroreflective sensing modes , dark operate is active when the beam is blocked. In diffuse, fixed field, and adjustable field sensor modes , dark operate is active when the target is absent. ## QS18W Indicators **==> picture [85 x 27] intentionally omitted <==** **----- Start of picture text -----**
