Product details

It amplifies the signal from a separate photoelectric sensor head, letting you set the sensing threshold without a separate programming tool. If the output is flaky, check the teach boundary before you chase a noise problem; the amplifier itself is straightforward.

Lifecycle stage is mature. The part is not new but remains in routine supply.
