IDEC Electronics has added background suppression types to its SA1E range of miniature photoelectric switches. The aim of the SA1E range is to provide a really low cost alternative in the main application areas for photoelectric switches. Prices start from just £31.
Measuring only 36mm by 19mm by 11mm, the SA1E switch provides through beam, retro-reflected (uses a reflector plate) and diffuse/spot reflected options (reflects from the object). The background suppression types offer a range 20 to 200mm.
