AC- and DC-powered sensors with solid-state outputs
For the latest technical information about this product, including specifications, dimensions, and wiring, see www.BannerEngineering.com
Features
• Choose models for 10 to 30V dc or 24 to 250V ac operation
• DC models have bipolar solid-state outputs: one NPN (sinking) and one PNP
(sourcing)
• AC models have an SPST solid-state output rated for up to 3/4 amp with simple 2-
wire hookup
• All models have a rear panel sensitivity adjustment and light/dark operate switch
• DC models include Banner’s Alignment Indicating Device (AID™) system
• Choose models with integral 2 m (6.5') cable or Mini-style QD (quick-disconnect)
connector; 9 m (30') cables are also available

* 9 m cables are available by adding suffix “W/30” to the model number of any cabled sensor (e.g., SMA91E W/30).
A model with a QD connector requires a mating cable; see Quick-Disconnect Cables on page 10.
WARNING: Not To Be Used for Personnel Protection
Never use this product as a sensing device for personnel protection. Doing so could lead to seri-
ous injury or death. This product 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 ener-
gized or de-energized sensor output condition.
