Frequently Asked Questions
What is Omron E3JK‑R4M1? Omron E3JK‑R4M1 is retroreflective‑type photoelectric sensor with 4 m sensing‑distance and 24 VDC supply‑voltage.
What sensing‑method does E3JK‑R4M1 use? Sensing‑method is retroreflective; external reflector accessory is required for normal light‑path operation.
What rated sensing‑distance for E3JK‑R4M1? Rated retroreflective sensing‑distance is 4 m when paired with proper reflector.
What supply‑voltage for E3JK‑R4M1? Nominal supply‑voltage is 24 VDC.
Can E3JK‑R4M1 work without reflector? No, retroreflective sensor needs matched reflector accessory to establish returning light‑beam path.
What detection logic for retroreflective sensor E3JK‑R4M1? Object passing between sensor and reflector interrupts light‑beam and triggers sensor output state‑change.
What to verify before ordering E3JK‑R4M1? Confirm full model number, retroreflective‑sensing‑method requirement, 4 m sensing‑distance requirement, compatible reflector accessory selection and 24 VDC field‑power‑supply condition.
