Frequently Asked Questions

Which sensing applications can use the 70 V collector-emitter rating?

The 70 V minimum collector-emitter breakdown rating provides output-stage headroom for object detection, mechanical position sensing, and pulse counting in suitable control circuits.

How does 100 nA maximum dark current affect detection?

A 100 nA maximum dark current helps limit off-state leakage, supporting clearer switching margins when the optical slot is blocked or unilluminated.

When comparing substitutes, should buyers match the 50 mA output?

Yes, an alternate should support the nominal 50 mA on-state collector current, the 60 mA forward-current limit, and compatible slotted mechanical geometry.
