OPB720B-12Z

Long Distance Reflective Switch OPB720A and OPB720B Series Features: 0.04 to 12 (1 mm to 305 mm) with 90% reflective material. (Typical Maximum detection distance to be set at factory) Recognizes objects as small as 0.08 (2 mm) Ambient light rejection < 100K Lux Open collector output Cable length 39 (990 mm) lead length 28 AWG wire Description: The OPB720A and OPB720B Series reflective switches detects objects as far away as 12 (305 mm) using standard 90% reflective material, and can detect objects as small as 0.08 (2 mm). The OPB720 series consist of three standard reflective switching distances -06Z for typically 6 (152 mm), -12Z for typically 12 (305 mm) and -30VZ for typically 30 (762 mm). The power supply voltage range of the OPB720A series is 10 to 30 volts while the power supply voltage range for the OPB720B is 4 to 7 volts. The OPA720A and OPB720B sensors are NOT affected by ambient light in most conditions. Ambient light conditions are compensated by using a synchronous driver detection scheme. This sensor has a logical output that switches from a high level with reflective target to a low level with no reflective target. With the addition of hysteresis, the OPB720 series minimizes output switching oscillations. The type of material used for the target is very dependent on the distance that can be achieved for the sensor. Taking this into consideration, the OPB720 series can be used in either a reflective or interruptive mode. As an example, the OPB720A-12Z can easily be used in a reflective mode for distances around 12 (305 mm) while when reflecting off a retro-reflective target similar to 3M 3870 or Nippon Crystallite at distances around 85 (216 mm) the device works well in the interruptive mode. See the included charts for typical distances with different reflective material for other versions of the OPB720 series devices. The OPB720 series has an open collector output transistor and power requirements are compatible with most PLCs and TTL gates.
