Industrial Fiber Amplifier for Machine Sensing

The Banner SM312FQD is a Mini-Beam infrared amplifier operating at 880 nm through glass fiber optics. It accepts a 10-30 V dc supply and provides bipolar output with one NPN and one PNP discrete channel. The rectangular thermoplastic housing features an M18 mount and achieves IP67 plus NEMA 1, 2, 3, 3S, 4, 4X, 6, 12 ratings for harsh industrial environments.

Integral M12 Quick-Disconnect Simplifies Wiring

A four-pin M12 Euro quick-disconnect connector is built into the housing, removing the need for separate cable glands or field wiring terminals. The connector carries both power and the bipolar signal outputs in a single plug-and-play interface. Potentiometer adjustments on the body allow sensitivity tuning without opening the enclosure or using a separate programmer.

Fast Mounting with Standard M18 Clearance

The M18 mounting thread lets technicians secure the unit in standard sensor cut-outs using common lock-nuts, so no special brackets are required. A 100 ms power-up delay prevents false triggers during system start-up, while 300 µs repeatability and 1 ms minimum response time suit high-speed detection tasks. Operating limits are -20 °C to 70 °C with 90 % humidity at 50 °C, so cold-storage or wash-down areas are within spec.

Questions about this item

Does the 10-30 V dc supply need periodic recalibration of the potentiometer?

The potentiometer adjustment is set during installation and does not require scheduled recalibration under normal operation.

Which limit appears first during continuous operation — the 70 °C maximum temperature or the 1 ms minimum response time?

The 70 °C maximum operating temperature is the thermal limit reached before any timing constraint becomes critical.

How much heat does the thermoplastic housing generate when powered at 30 V dc all day?

The unit operates up to 70 °C ambient with IP67 sealing; no active cooling is needed and surface temperature stays within the rated range.
