Through-beam photoelectric sensor, block type
ISF IDEC

Rugged, waterproof photoelectric sensors with universal voltages. Available in free-voltage type (24 to 240V AC) and DC type (10 to 30 VDC, PNP/NPN transistor, open collector output). Both types of photoelectric switches are also available with a time-delay output. Sixteen models in all.

Key Features
- Available in free-voltage type, all available with time delay
- Featuring through-beam sensing between the projector and receiver, with sensing range of 32' to 9-3/4" (10m)
- Diffuse-reflected light sensing, as well as retro-reflected
- Available with three time delay modes (one-shot, on-delay, or off-delay) selectable from 0.1 to 5 seconds
- DC sensors have dual NPN/PNP transistor outputs
- Diffuse-reflected light sensors feature a sensitivity adjustment control
- All units are selectable: light on or dark on
- Unique touchdown terminals reduce wiring time
- Protection rated IP66
