SICK PSK1 Photoeye Corner Mirror For Reflective Optical Sensing

PSK1 Corner Mirror from SICK is a deflector mirror used to route a photoelectric beam around a corner in reflective optical sensing setups. The mirror features a reflector surface of 96 mm by 124 mm and is designed for horizontal deflection in corner-mount configurations (part number 1005229, PSK1). In practice, PSK1 serves as the deflector mirror for SICK photoelectric systems such as the WSU/WEU26-3 single-beam safety switches, enabling reliable sensing when the light path cannot be arranged in a straight line. When installing more than two mirrors, precise alignment is critical, and the AR 60 alignment aid is recommended to achieve accurate beam geometry. This accessory is intended to extend sensing around corners in industrial environments, preserving detection reliability in tight spaces or around obstructions by redirecting the emitted beam through the corner path, rather than replacing the sensor or restructuring the line.
