window; one NPN (current sinking) or one PNP (current sourcing),
depending on model.
Indicators

(Amber/Red)
Range Indicator: Green - Target is within sensing range; Red - Target
is outside sensing range; OFF - Sensing Power is OFF
Teach/Output Indicator: Amber - Target is within taught limits; OFF -
Target is outside taught window limits; Red - Sensor is in TEACH mode
Output Protection
Protected against short-circuit conditions

Temperature Effect
Non-encapsulated models: ± 0.05% per °C from –20 to 50 °C, ± 0.1%
per °C from 50 to 60 °C
Encapsulated models: ± 0.05% per °C from 0 to 60 °C, ± 0.1% per °C
from –20 to 0 °C
Application Notes
Required Overcurrent Protection
1. If supply voltage is > 24 V dc, derate maximum output current 5
mA/°C above 50 °C.
2. NPN off-state leakage current is < 200 µA for load resistances > 3
kΩ or optically isolated loads. For load current of 100 mA, leakage is <
1% of load current.
WARNING: Electrical connections must be
made by qualified personnel in accordance
with local and national electrical codes and
regulations.
3. Objects passing inside the specified near limit may produce a false
response.
Overcurrent protection is required to be provided by end product
application per the supplied table.
Overcurrent protection may be provided with external fusing or via
Current Limiting, Class 2 Power Supply.
Supply wiring leads < 24 AWG shall not be spliced.
