OPB720A-06Z - Long Distance Reflective Switch
The OPB720A and OPB720B series reflective switches detect 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.
The OPB720 series has an open collector output transistor and power requirements are compatible with most PLCs and TTL gates.
The OPB720A-06Z is a Long Distance Reflective Switch with maximum detection of 0.04” to 6” (1.0 mm to 152 mm) rated for operating temperature range from 0°C to + 50°C.
