Photoelectric Sensors Seek Rugged Terrain

Pumped for harsh and rugged duties, the PX series photoelectric sensors carry an IP-69K environmental rating, which allows them to withstand pressure levels up to 1,400 psi in wash-down applications and temperatures to 176°F. The sensor heads are backfilled with epoxy under vacuum conditions and employ scratch-resistant lenses. Seven water and oil resistant types of sensor heads are available to meet the needs of high-pressure wash down applications. The sensors also enlist high-intensity LEDs that combine infrared or four-element red LEDs with optical-quality glass lenses. The PX-H71 thru beam (20m) and PX-H61 reflective (2m) components produce a visible red light while the PX-H72 produces an infrared beam that handles detection distances up to 40m. For additional protection of the sensor heads, stainless steel guard units are available. The PX Series also includes the hex shaped PX-H71TZ (20m) with a 90° bend in its cable to prevent entanglements. KEYENCE CORP. OF AMERICA, Woodcliff Lake, NJ. (888) 539-3623.
