WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel
protection. Doing so could lead to serious injury or death. This
device does not include the self-checking redundant circuitry necessary to
allow its use in personnel safety applications. A sensor failure or
malfunction can cause either an energized or de-energized sensor output
condition.

Standard 2 m (6.5 ft) cable models are listed. To order the 9 m (30 ft) cable model, add suffix "W/30" to the cabled model
number. (e.g., 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 the model number (e.g., QS18WEQ2). 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 (e.g., QS18WEC1).
1MOSFET: Metal oxide semiconductor field-effect transistor.
