FREMONT, CA – Scientific Technologies, Inc. (STI) introduces the TL4024 series safety interlock switch with guard door locking. The TL4024 features a high locking force of 1500 N (337 lb.) for maximum protection, and uses a total of four contacts to monitor safety, door position, and lock status. This switch features LED indicators for easy recognition of the door’s safety status. When used with a stainless steel actuator, the TL4024 provides a minimum of one million actuations.

The narrow profile facilitates mounting on 2-inch square tubing or in space-restricted applications, while a NEMA 6 anodized die-cast metal housing allows the switch to withstand water washdown environments. A rotatable head provides eight possible actuator entry points for versatile installation. An optional heavy-duty yellow slide bolt with integral door handle facilitates easy integration on machine guards, and permits the attachment of multiple padlocks. A key release is available that allows manual unlocking of the switch. The TL4024 conforms to all European safety standards and is UL, c-UL and CE listed.

With headquarters in the heart of Silicon Valley, STI was founded over 30 years ago and employs more than 340 people. STI has been selected twice by Forbes and three times by Business Week as one of the “world’s best small companies.” STI’s safety products are used to protect workers around machinery, automated equipment and industrial robots.
