• Manufacturer Part Number: SM312FPH
• Description: Photoelectric Sensor
• Manufacturer: BANNER ENGINEERING
• Type: Photoelectric Sensorr

Specifications of SM312FPH

• Sensor Output: NPN/PNP
• Sensing Range Max: 3m
• Switch Terminals: Quick Connect
• Sensing Range Min: 10mm
• Sensor Input: Optical
• Fiber Optic Sensor Type: Photoelectric Sensor

Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than 25 mA
(exclusive of load)
Supply Protection Circuitry
Protected against reverse polarity and transient voltages
Output Configuration
Bipolar: One current sourcing (PNP) and one current sinking (NPN) open collector
transistor
Output Rating
150 mA maximum each output at 25° C, derated to 100 mA at 70° C
(derate ≈ 1 mA per ° C)
Output Protection Circuitry
Protected against false pulse on power-up and continuous overload or
short-circuit of outputs
Output Response Time
Sensors will respond to either a “light” or “dark” signal of 1 millisecond or longer duration,
500 Hz maximum. Modification for 0.3 millisecond response is available (MHS-suffix
models; these models also feature reduced sensitivity range and reduced repeatability.)
NOTE: Outputs are non-conducting during 100 millisecond delay on power-up.
Repeatability
Response time and repeatability specifications are independent of signal strength.
Glass Fiber Installation
1) Install the O-ring (supplied with the fiber) on each fiber end, as shown in the
2) While pressing the fiber ends firmly into the ports on the sensor front, slide

WARNING . . .
Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.
These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety applications. A
sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current Banner

Specifications
Adjustments
Light/Dark Operate Select switch
15-turn slotted brass screw Gain (sensitivity) adjustment potentiometer (clutched at both
ends of travel)
Located on the rear panel, protected by a gasketed, clear acrylic cover.
Indicators
Patented alignment Indicator Device system (AID™, US patent #4356393) lights a rear-
panel-mounted LED indicator when the sensor sees light. Its pulse rate is proportional to
the light signal strength (the stronger the signal, the faster the pulse rate).
Construction
Reinforced thermoplastic polyester housing, totally encapsulated, o-ring sealing, acrylic
lenses, stainless steel screws
Environmental Rating
Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 6, 12, and 13; IEC IP67.
Connections
PVC-jacketed 4-conductor 2 m (6.5') or 9 m (30') cables, or 4-pin Euro-style QD fitting;
QD cables available separately.
Operating Conditions
Application Note
The NPN (current sinking) output of dc MINI-BEAM sensors is directly compatible as an
input to Banner logic modules, including all non-amplified MAXI-AMP and MICRO-AMP
modules. MINI-BEAMs are TTL compatible.
Certifications
1) With supplied fiber cutter, make a clean cut at control ends of fibers.
2) Unlock the fiber gripper as shown below. Apply appropriate fiber adaptors prior
3) Gently insert the prepared fiber ends into the ports, as far as they will go.
4) Slide the fiber gripper back to lock, as shown below.
