Takachi Electric Industrial has been manufacturing enclosures and cases in Japan since the 1950s, and its catalogue reflects that long, narrow focus: rather than a broad electrical portfolio, Takachi builds precision aluminium and die-cast enclosures, heat sink cases and instrument housings, and does little else. Our stock is almost entirely split between its AWN aluminium heat sink case range and its BDN die-cast aluminium enclosures.
The AWN series is a finned aluminium extrusion case, sold in black or silver finishes across a wide run of width/length/height combinations, designed to conduct heat away from the electronics mounted inside it — a natural fit for power supplies, amplifiers and driver circuits that need passive cooling without a fan. The BDN series takes the opposite approach: a sealed die-cast aluminium enclosure rated IP67, built for outdoor or washdown environments where keeping moisture and dust out matters more than shedding heat. Between the two ranges, Takachi covers most of the "small electronics enclosure" spectrum from passively-cooled indoor cases to weatherproof outdoor housings.
Because Takachi's stock overlaps heavily with our broader Enclosures & Cabinets category, use that page if you're comparing enclosure options across brands; come here specifically when you already know you need Takachi's AWN or BDN dimensions, finish or IP rating matched to an existing design. We are not Takachi Electric Industrial, and not an authorised Takachi distributor — we source and supply genuine Takachi enclosures from our own stock.
Frequently Asked Questions
Q: What's the difference between the AWN and BDN series?
A: AWN is a finned aluminium heat sink case designed for passive cooling of internal electronics; BDN is a sealed IP67 die-cast enclosure designed to keep moisture and dust out. Choose AWN when heat dissipation matters most, BDN when environmental sealing does.
Q: Are Takachi enclosures pre-drilled or machined for mounting?
A: Standard stock is supplied as plain enclosures; check the specific product listing for any pre-machined options, as most require custom drilling or machining to fit your PCB and connectors.
Q: Can AWN heat sink cases be used outdoors?
A: AWN cases are not sealed to the same IP67 standard as BDN enclosures, so they're better suited to indoor or protected installations — for outdoor or washdown use, the BDN series is the closer match.
