The PC-100 is a portable sensing head with TTL output. It is designed to detect LED flashes in meters such as electricity meters. It incorporates a small housing design that makes it even lighter in weight but still rugged with its ABS and Polycarbonate filter material. All devices with LED flash pulser will work with this product.

PC-100 can detect typical LED colors: Red, Orange, Yellow, Green and Infrared. The output pulse rate can be divided into 10 or 100 via a user selectable push button. In addition, a 3-color LED indicates the status of the output pulse division:

  • Green 1:1 (max pulse speed: 10 Hz)
  • Red 10:1 (max pulse speed: 100 Hz)
  • Orange 100:1 (max pulse speed: 1000 Hz)

PC-100 does not have a connector, which is suitable when the consumption data is supposed to be read out by any device, such as a handheld device, that supports the TTL output port. It derives power from the TTL port, so there is no need for external battery pack or AC adapter. PC-100 benefits from a very strong magnet that firmly attaches the optical probe to the meter and also has resistance to external light influences. Installation and configuration instructions are included with the probe.

Ergonomic & User-friendly Housing Design

The housing is designed to be fit in the hand of the user easily and the material used makes it strong and also light weight. It is resistant against surface wear off in long term usages that is caused by using the optical head on the meters and devices with optical port installed on them.

Good material not always brings good hardness. The housing shape can have tremendous effect on the hardness of the probe. We have designed the optical probes to withstand falling from one meter height, in case it slips from user’s hand.

Powerful Magnet

The head contains a powerful magnet on under the surface in which the probe is attached to the optical port, that causes the probe to stick to the optical port and not easily removed, in order to secure connection to the device and let the user work without needing to hold the probe in position with one hand.

Warning: due to strong magnetic force of the magnet used in the probe, please do not store it beside electronic equipment, because it can damage these devices in long time storage. It also causes malfunction in any storage device like hard drives, solid-state memories (flash memories, SSD drives and etc.), RAM storages and etc.

Optical Filter

In order to detect LED flash pulse light, a certain wavelength must be used. The wavelength used must be in the range of red, orange, yellow, green and infrared light. The light filter used in this scanning head filters out all interfering lights, preventing any disturbance to the sensing process, thus providing stable and efficient sensing of the device’s LED flash pulser.

High Quality Cable

Using a product that utilizes a wired connection, the wire is always prone to disconnection due to lots of bending and stretches. The strong and high-quality cable used in our wired optical probes provides long term and efficient usage.
