IDEC SA1N subminiature photoelectric sensors

IDEC Corporation has expanded its photoelectric sensor range with the SA1N series of space-saving subminiature PE sensors.

For industrial equipment, the intersecting trends of increasing automation and reduced installation space mean that designers need compact and high-performance technologies for discrete sensing applications. General-purpose sensors simply don’t fit, and other technologies such as fibre optic devices are more costly and require separate amplifiers which complicate installation requirements.

The SA1N subminiature sensors are available in two versions: a barrel-mount fibre-type diffuse-reflective infrared LED style, secured with M6 nuts through a mounting hole; and a block-type convergent-reflective red LED sensor, secured with two mounting holes located at a 14 mm pitch.

Both versions are all-in-one devices with built-in amplifiers and sensitivity adjustment control. The barrel-mount version has a 3-50 mm sensing range, while the block-type can detect over a 5-30 mm sensing range. Both models are available in NPN or PNP light-on configurations, and both provide a rapid 0.5 ms maximum response time.

The sensors each come with flexible 2 m pigtail wiring, functioning at standard 24 VDC with minimal current draw. They operate over a wide -25°C to +55°C temperature range. The barrel-mount version uses a stainless steel housing and plastic encapsulation to achieve an IP67 rating, while the block-type is rated at IP64.
