If you're sourcing security equipement for bulk deployment, the usual headaches are inconsistent quality and documentation that doesn't hold up under scrutiny — we've been through that with other suppilers ourselves.
The DM239A runs on a standard 9V battery, which is good because replacements are easy to find anywhere, and it draws about 20mA in use or 3mA on standby, so battery life is decent for a shift or so. It's ABS plastic, roughly 350g without the battery, and the dimensions are 410×85×45mm, which makes it light enough to carry all day but not flimsy. Detection uses electromagnetic induction, and you get three alarm modes: sound, vibration, or both together — most buyers we deal with just leave it on sound+vibration for crowded areas.
Operating temp range is -10°C to 50°C, and storage goes form -20°C to 60°C, so it handles outdoor use fine as long as you're not in extreme cold for hours. The humidity spec says up to 95% RH non-condensing, which basically means it's okay for sweaty hands or light rain but don't dunk it. One thing we've noticed handling these is red LED for target detection is bright enough to see in direct sunlight, which isn't always the case with cheaper units.
We can customize the color, logo, or packaing for your bulk order — the MOQ for OEM work is usually 500 units, but we've done smaller runs for specific clients if you're flexible on lead time. The standard accessories include the main unit, a manual, one 9V battery, and a leather carrying case, but our company can swap the case for a nylon pouch or add a lanyard if that's more your crowd. It's CE and RoHS compliant, and our company provide a COA with every shipment — though if you need HPLC or other specific test data, that's extra and takes about a week to arrange.
Payment terms are typically 30% deposit with the balance before shipment, but we've done T/T or L/C for regular buyers — just confirm when you place the order. Shipping from our warhouse is usually via sea freight for bulk (20-30 days depending on port) or air if you're in a rush, though air adds about 40% to the freight cost. We keep about 2000 units in stock at any time, but if you're ordering over 5000, give us a heads-up so we can schedule production — lead time for that is roughly 4 weeks.
We typically start at 500 units for the DM239A, but if you're testing the market, we can discuss a smaller trial order. Just let us know your volume and we'll see what works.
Lead time is usually around 15-20 working days after order confirmation and payment. If you need rush delivery, we can expedite for a small surcharge.
Absolutely. We'll send you the CE and RoHS compliance documents right away. Just drop us a message and we'll share them as PDFs.
Yes, we can print your logo on the unit or the leather case, and we also offer custom box packaging. MOQ for customization is usually 1,000 units.
Keep them in a dry, cool place between -20°C and 60°C, with humidity under 95% RH. The ABS plastic handles that fine, but avoid direct sunlight for long periods.
