Product questions
What is the sensing range and adjustable cutoff of the RLK28-8-H-2000-IR-Z?
For the /31/116 version, the specified detection range is 20–2000 mm; the sensing range adjustment is 200–2000 mm. These are different specifications: the cutoff is not adjustable down to 20 mm.
What supply voltage and output does this sensor use?
The /31/116 version uses a 12–240 V AC/DC supply and a changeover relay output. The relay is rated up to 250 V AC/DC and 2 A, with maximum switching power of 50 W DC or 500 VA AC. Check all load limits for the intended circuit.
How is the RLK28-8-H-2000-IR-Z/31/116 connected?
It has a terminal compartment with eight spring-loaded terminals for 0.5–1.5 mm² conductors and an M16 × 1.5 cable gland. Verify the full suffix and manufacturer wiring diagram before connecting it.
Which timer functions are available on the /31/116 sensor?
The programmable functions include on-delay, off-delay, one-shot, on-delay plus one-shot, and on-delay plus off-delay. The stated adjustment interval is 0.1–10 seconds.
Will this sensor replace the unit on my equipment?
