Slim and tough sensor head for use in harsh environments *1 Although the housing is very slim, the sensor head provides ultra-high rigidity. Metal is used for the outer housing, inner housing, and locking mechanism components to provide *3 *2 strength and allow the sensor head to endure vibration or impact. *1: Strong, lightweight aluminum outer housing with 1.6 mm 0.06" thick walls *2: Specially molded inner housing prevents foreign matter entry. *3: Stereoscopically molded tough steel structural member LED bar indicator simplifies optical alignment The number of lit LEDs on the bar varies depending on the number of clear optical axes. Anyone can easily perform optical alignment with no assistance. In addition, if a fault occurs, the indicators inform the operator of the fault status * instantly. * When all optical axes are stably clear, all LEDs are illuminated and the LED color changes from red to green. Sub-controller enables two-head operation The sub-controller enables two- sensor heads to be used without extra wiring. When a sub-controller is connected to the main controller, the mutual interference suppres- sion function works automatically. Space-saving safety controller The controller features fault detection circuits plus three safety relays. U cus OSHA L The controller is highly compact for easy mounting to a DIN rail.

One “Normally open” Lockout status is one of the sensor’s non-hazardous contact and one “Nor- statuses, in which all of the outputs are open and the mally close” contact are machine is stopped. connected and move Interconnected together. If one relay becomes immobilized by a welded contact, the welded contact can be detected based on the contact gap of the other relay. This ensures safety. Fail-safe A fail-safe system operates to ensure safety if a failure should occur in the system. If ambient light is received or the output circuit is damaged, for example, an ordinary photoelectric sensor cannot stop the machine even if a person accesses the hazardous area on the machine. Therefore, such a sensor cannot be regarded as fail-safe. The PJ-V Series performs a self-check using two indepen- dent circuits to detect a failure in the circuits, ambient light entry, or a welded relay contact. Therefore, they are high- level fail-safe sensors that reliably stop the machine in an emergency. 183 MAIN MENU PRODUCTS APPLICATIONS INDEX SELECTION GUIDE Expandable Safety Light Curtains PJ-V Self-diagnostic circuit This circuit detects an internal failure in the PJ-V Series.
