The IWP Infrared Wireless Programmer configures SensorSwitch TLS Twist-to-Lock Sensors from the floor using infrared communication. Passive Powerless Programming (PPP) technology allows adjustments to sensor settings while sensors are unpowered or in the package. Ideal for large spaces like warehouses, it eliminates the need for lifts or ladders, making sensor configuration safer and more efficient. The IWP features a bright, backlit display, visual feedback for confirmation, and an integrated light meter for relative photo measurements.
