The new SA1N series of space-saving subminiature photoelectric sensors is available in a barrel-mount fiber-type diffuse-reflective infrared LED style, secured with M6 nuts through a mounting hole; and a block-type convergent-reflective red LED style, secured with two mounting holes located at a 14mm pitch. Both versions are all-in-one devices with built-in amplifiers and sensitivity adjustment control. The barrel-mount version has a 3 to 50 mm sensing range, while the block-type can detect over a 5 to 30 mm sensing range. Both models are available in NPN or PNP light-on configurations, and both provide a rapid 0.5 m sec maximum response time. The sensors come with flexible 2-meter pigtail wiring, functioning at standard 24V DC with minimal current draw. They operate over a -25 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.
