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.

Overview
The SLO Series Slot Sensor (sometimes called a “Fork Sensor”)
comprises an opposed-mode emitter and its receiver inside a
single convenient housing.
Opposed-mode sensing is very reliable, and the single self-
contained housing provides easy installation, with no sensor
alignment required. In addition, the molded-in arrow on the
emitter portion of the housing and the slotted design on the
receiver portion of the housing show at a glance the position of
the beam, simplifying installation placement.

To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, SLO30VB6 W/30. Models with a quick
disconnect require a mating cordset.
