Omron STI's New F3SJ Safety Light Curtains Simplify Selection and Installation,
and Save Space, in OEM or Retrofit Applications

F3SJ Safety Light Curtains from Omron Scientific Technologies, Inc. make selecting and installing a safety light curtain easier than ever - users need only specify the required configuration type and sensor length. F3SJ safety light curtains are available in finger protection, hand protection or hand/limb body protection configurations. Sensors with protective heights of up to nearly 2.5 meters are available for applications that involve large-sized workpieces.

The F3SJ safety light curtain is 6 mm thinner than previous models, and when used with the newly designed mounting brackets that allow beams to be aligned after the sensor is mounted, the total thickness is just 26 mm - a reduction of 19 mm. The low profile allows users to add safety to existing equipment without the safety light curtains getting in the way. F3SJ cables (0.3 m) have M12 connectors and a 5mm bending radius, and can be routed in literally any direction, for simplified wiring. Up to 4 sets, or 400 beams, can be connected in series, and with series connection cables up to 15 meters in length users can effectively safeguard a wide area.

All F3SJ safety light curtain system parameters can be set with intuitive software, and system status can be checked with a laptop computer. When a computer isn't the most convenient tool for the worksite, an optional Setting Console is a handy way to set parameters, monitor system status, and quickly troubleshoot errors. The F3SJ can be used to configure a Category 4 safety circuit to suit a variety of safety needs, including options to maximize space efficiency and minimize set-up costs, reduce wiring time and costs, or even implement a multi-input safety circuit. Many other safety light curtains require a dedicated "muting controller" to benefit from muting functions, but it is built into the F3SJ and can be used by simply replacing the unit's cap with an optional muting key cap.

New Guard Locking Safety Door Switch from Omron STI Boasts
World's Top Holding Force of Any Switch in it's Class

Omron Scientific Technologies, Inc. introduces the D4JL guard locking safety door switches. The IP67 rated switch provides an incredible holding force of 3,000 N (674 Lbs.), making it a perfect solution for safely locking the largest and heaviest of doors. Two safety circuits and two monitor contacts provide an array of monitoring patterns, including monitoring the open/closed status of the door and the status of the lock. Standard gold-clad contacts enable use with microloads and ordinary loads

D4JL models are available with rear release buttons that allow workers to unlock the switch from inside the protected area and exit the hazardous areas. Trapped key models are also available, and are designed to prevent workers from being locked in hazardous work areas. With trapped key models, the door can be opened only by supplying power to the solenoid to release the trapped key lock, and then turning and removing the trapped key. As long as a person has the trapped key when he enters a hazardous area, he cannot be accidentally locked inside. It is not possible to enter the hazardous area without the trapped key because the trapped key must be removed to open the door. Thirty different types of trapped keys are available for use in applications with adjacent hazardous areas.
