Panasonic ET-PEN100 is an interactive light pen designed for use with compatible Panasonic interactive projectors. It combines infrared position detection, touch-sensitive operation, and wireless pen interaction to enable writing, drawing, annotation, and mouse control directly on the projected image. The pen operates in conjunction with the projector's built-in infrared sensor and interactive software, and cannot function as a standalone device.
ET-PEN100 features a pressure-sensitive tip with integrated infrared emitter, single-button operation, and is powered by two AAA batteries. It supports interactive annotation, mouse click-and-drag functionality, and digital whiteboard applications on compatible Panasonic interactive projectors. Compatible models include PT-TW381R, PT-TW371R, PT-TW351R, PT-CW331R, PT-CW241R, PT-CX301R, PT-TW343R, PT-TW341R, PT-TW331R, PT-TX301R, and PT-TW231R.
