SLM Series Slot Sensors
Slot Opening 10, 20, 30, 50, 80, 120, 180, or 220 mm (depending on model); beam is 5 mm (0.2") from outer edge
Supply Voltage and Current 10 to 30V dc (10% ripple) @ less than 25 mA, exclusive of load
Supply Protection Circuitry Protected against reverse polarity and transient voltages
Output Configuration Cabled and Euro-style QD models: Bipolar: One current sourcing (PNP) and one current sinking (NPN)
Pico-style QD models: Current sourcing (PNP) or current sinking (NPN), depending on model
Output Rating 100 mA with short circuit protection
OFF-state leakage current: < 10 µA sourcing; < 200 µA sinking
ON-state saturation voltage:
NPN: 1.6V @ 100 mA
PNP: 2.0V @ 100 mA
Output Protection Circuitry Protected against output short-circuit and false pulse on power up. 100 ms max. delay at power up; outputs do not
conduct during this time.

Certifications
Specifications
* Minimum Object Detection: Smallest diameter rod that can be detected when passed slowly through sensing beam
NOTE: Minimum object detection is measured midway between the emitter and receiver. For best results, objects to be detected should be placed in the midway position
when possible. The minimum object detection size may increase if the object is very close to the receiver side.
**Hysteresis: Distance an object must move to toggle between output OFF and output ON state
***Repeatability: Variation in switching distance for a standard target at controlled sensing conditions
