Overview

ISO 18000-3 Mode 2 Phase Jitter Modulation (PJM) RFID is the answer for situations where large volumes of tagged items need to be quickly and accurately identified. On top of providing 100% accuracy, (PJM) RFID it is especially designed for dynamic situations where items are stacked or stored in any orientation.

Features

100% Accuracy – Guaranteed accuracy for all tag replies

Close Stacking– Our PJM Stacktag® inlets are specially designed so that they are able to be identified, read and written to when stacked closely together

Orientation Insensitive – Our range of tunnel and desktop readers power tags in three dimensions, enabling them to be read in any orientation

High Speed Data Rates – The unique reply system implemented in PJM products enables tags to be read virtually immediately. PJM tags have a command data rate of 424 kbits per second and a maximum effective reply data rate of 848 kbits per second.

Robust – PJM tags have the ability to frequency hop and reply on any one of 8 discrete channels. With 8 discrete channels where one channel is blocked, for whatever reason, there are seven other channels a tag can use to reply.

Anti-Collision – PJM tags use a unique anti-collision method when talking to readers that is at least 10 times faster than all other anti-collision methods and suffers no loss of reader performance with up to 32,000 tags simultaneously being read.

Large Memory Capacity – PJM tags have a 4kbit OTP memory. This is unique as only the very high data rates provided by PJM RFID can reliably use this large memory in extremely large, tightly packed tag populations or in high speed dynamic environments.
