EnOcean has added a new switch module supporting the EnOcean radio standard in 868 MHz to its product portfolio that is explicitly designed to enable wireless toggle switch devices. Like the PTM 21x family, the new PTM 202 module works battery-free, gaining its energy by the press of a button. PTM 202 is also built in the established original PTM form factor which makes it compatible with a wide range of single rocker switch designs. Common applications for the PTM 202 modules are toggle switches, central on/off switches as well as switch/actor bundles for retrofitting existing buildings.
No batteries or wires needed
Like all PTM modules from EnOcean, PTM 202 is powered by the electro-dynamic generator ECO 200 that is actuated by pushing one of the two sides of the top side (O or I; see picture) to the end position of the module. This means that the module doesn’t need any batteries or wires to function, and that it operates completely maintenance-free. Moreover, wireless products that use the PTM 202 module can be placed anywhere in the room which makes them ideally suited for retrofitting existing buildings, hermetically sealed systems or locations that are generally difficult to reach.
Following on from the success of the PTM family, EnOcean is using the proven original PTM form factor – the international industry standard for wireless radio-based switches – for this new module. This allows PTM 202 to fit into all common single rocker switch designs.
Focus on the core function of a switch
EnOcean is constantly expanding its portfolio of self-powered modules with innovative new products. With the PTM 202 module the company focuses predominantly on the simplicity and convenience of operating a single rocker switch and with that picking up a concept that was first introduced 20 years ago: The energy harvesting module provides the handling of a classic switch, where the rocker keeps the position, representing the actual switch status. This means the module will toggle and keep the last position it has been pushed into (0 or I). This feature makes it particularly convenient for end users: One glance at the switch is enough to determine whether e.g. lights are turned on or off.
Proven in practice
TRIO2SYS, French designer and manufacturer of wireless and battery-free solutions, is one of the first partners who has already tried and tested the new PTM 202 module: “We have been very curious to get our hands on this new wireless switch module from EnOcean, focusing on the core function of a switch, and of course we have not been disappointed. We appreciate the unique handling of a battery-free bi-stable toggle switch that is completely maintenance-free for all sorts of projects in smart buildings and that is optimized for cost-sensitive applications. All in all, it’s another well-done energy harvesting product from EnOcean,” says Yannick Rouet, Sales Manager at TRIO2SYS.
