Product Description

The Keyence PH-614A is a compact, high-precision proximity sensor designed for detecting the bottom dead center (BDC) position in mechanical systems. Its flat, reflective design allows for accurate detection of small or closely spaced objects, making it ideal for applications requiring precise position sensing. The sensor offers both Light-ON and Dark-ON output modes, providing flexibility for various control systems. With a response time of 0.5 ms and a spot diameter of approximately 2.5 x 4.5 mm at 15 mm detection distance, it ensures quick and accurate detection. The PH-614A is housed in a durable SUS316L stainless steel casing and is rated IP67, IP69K, and NEMA 4X, 6P, 13, ensuring reliable performance in harsh industrial environments.​
