Aiphone AC-PF-40 - Series 40-bit Weigand Format Proximity Key Fob with Brass Ring

The AC-PF-40 proximity fob is built for the Aiphone AC-PROX-C proximity reader. It reads at 125kHz in Aiphone's 40-bit Wiegand format, so the reader and the credential have to be on that same format for the fob to enroll and present correctly.

No. The AC-PF-40 is encoded in Aiphone's 40-bit Wiegand format at 125kHz. A panel or reader expecting standard 26-bit Wiegand will not read the credential data correctly, so if your system is 26-bit you need a credential matched to it rather than this fob.

Both are printed right on the credential. The AC-PF-40 carries its site code and card number on the fob itself, so you can enroll it into the system by reading it off the part instead of presenting each one at a reader. That matters when a property manager is issuing a batch of fobs to tenants and needs the numbers logged against names.

The fob is a passive 125kHz credential, so there's nothing to wire, power, or program at the fob itself. What you do need is the AC-PROX-C proximity reader on the door side, since that's the reader the AC-PF-40 is designed to work with. Order one fob per user you're issuing to; the site code and card number are already printed on each one for enrollment.

Yes. The AC-PT-40 proximity disk tag is also Aiphone 40-bit Wiegand, the same format as the AC-PF-40 fob, so both credential styles can be enrolled on the same AC Series proximity setup. Useful when some users want a keyring fob and others want a tag stuck to a phone or a badge.

The body is ABS with a brass ring for the keyring attachment. It's a commercial-duty credential, and at 1/8 inch thick with a metal ring rather than a molded plastic loop, the attachment point is the part least likely to fail on a daily-carry key ring.
