Twilight sensor AR-022-DP01

AR-022 — Explosion-proof Twilight Switch

Compact twilight switch for zones 2/22 (gas/dust), based on a highly sensitive photodiode. It automatically turns the load on/off based on lighting, has adjustable sensitivity and delay, and two outputs: a main AC with high load capacity and an additional potential-free contact. Die-cast aluminum, steel handle, and IP66 sealing ensure operation in harsh industrial environments.
