The TESF Series is designed for use with hinged machine guards which must be closed for operator safety. Their tamper-resistant design and positive-opening NC contacts provide a significantly higher level of safety than conventional, spring-driven limit switches or proximity switches often used to monitor hinged guard positions.
Their compact, low-profile design and IP65 rating make them ideal for interlocking hinged safety guards in industrial environments. Designed to mount directly on the hinged guard and its stationary frame, it is easy to install on a wide range of extruded aluminum guard sizes and other guard styles.
Among its unique features is its ability to adjust the switching point in the field to meet specific application requirements. Once adjusted, the switching point is easily permanently locked to prevent further adjustment by unauthorized personnel. In addition, it features top or bottom cable entries, 1 NO or 2 NO and 2 NC contacts, designs suitable for inside or outside-guard mounting, and the ability to open a full 180°.
