IDEC SA2E family features standardized ASIC design for faster responses, better detection.

IDEC Corporation introduced its SA2E general-purpose photoelectric (PE) sensor family that includes five major models. The line features a new ASIC that provides improve response times to 0.5ms, compared with 1.0ms for previous generation models. Depending on the model, sensing distances can range up to 20m for through-beam, up to 5m for retro-reflective, and between 10mm and 1000mm for other reflective models. Sensors are switchable between “light-on” and “dark-on” operating modes, and applicable models have an on-board sensitivity or range adjustment potentiometer. The devices consume between 20mA to 35mA, at supply voltages of 12VDC to 24VDC, with the ability to switch up to 100mA maximum. The line is built to operate in a range of -30° to +55°C.
