Gewiss GW20821 — Infrared Movement Detector - 230V Ac 50/60Hz - 1No 3A(Ac1) 250V - 1 Module - System White

The Gewiss GW20821 is an infrared movement detector operating on a 230 V ac 50/60 Hz supply voltage, featuring 1NO 3 A (AC1) 250 V ac output contacts within a 1-module technopolymer white housing. Built to EN 60669-1 and EN 60669-2-1 standards, this device incorporates screw wiring terminals that accommodate solid cables from 0.5 to 2x2.5 mm² and stranded cables from 0.75 to 2x4 mm². The unit withstands a test voltage of 2000 V at 50 Hz for 1 minute, demonstrates insulation resistance greater than 5 MOhm, and delivers a prolonged operation switch durability of 40,000 position changes at In 250 V ac cosφ=0.6.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Gewiss references — within one business day.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
