1. GENERAL DESCRIPTION
The energy module ECO 100 is an energy converter for linear motion. It can be used
to power the PTM 230 radio module or derivates.
The energy output at every actuation of the spring is sufficient to transmit 3 sub-telegrams
with a PTM 230 module. Possible applications are miniaturized switches and sensors in building
technology and industrial automation.

1.1 Functional Principle
Spring
Figure 1: Electro-dynamic energy harvester ECO 100
A common electro-dynamic energy transducer is actuated by a spring, which can be pushed
from outside the device. When the spring is pushed up or down, electrical energy is provided
at the energy output pins. With this amount of energy it is possible to transmit an RF telegram
with a connected PTM 230 module.
1.2 Typical Applications
• Wireless switches for building automation
• Wireless position switches for industrial automation
• Call button transmitters

2. APPLICATION INFORMATION
Mechanical characteristics:
Important notes:
• It is recommended to mount a PCB on top of ECO 100 in order to avoid forces at the
energy output pins and to reduce dust inside the energy converter.
• If no PCB is mounted thin wires should be used for the connection between ECO 100
and the radio transmitter.
• For mounting the PCB please use screws of type EJOT KB 22x5.
• The soldering pins are designed for 0.8mm thick PCBs.
• The spring needs play of 0.4mm within operating lever as shown in Figure 4
