Sensor Connection Terminal Blocks from ASI Simplify Sensor Wiring

3-Wire Sensor Terminal Blocks

The TLS.2/GR is the most cost effective, easy-to-install 3-wire sensor terminal block on the market.  The TLS sensor terminal block comes equipped with jumpers on levels one and two, where you make the power connections for each sensor.  This is called the lock system.  The top level is for the signal connection of the sensor to the controller.  When you slide the TLS sensor terminal block to the next sensor terminal block or to the power distribution 3 level terminal block TLD.2 you simply slide the "lock system" fork under the screw on the adjacent block, tighten it down and your power or common connection is made.  Power for the sensors is brought into the TLD.2 3 level terminal block and then distributed to the TLS sensor blocks.

The TLS.2 sensor termination terminal block is also available with an LED between the lower or intermediate level and upper level for NPN or PNP sensors in order to give a visual indication of operation right at the terminal block for ease of testing and system troubleshooting.

TLS.2/U Cat. No. TL110 (with green LED between upper and lower levels)
TLS.2/T Cat. No. TL120 (with green LED between upper and intermediate levels)

The TLD.2 is a 3-level feed through terminal block that is used in high density wiring applications.  It is also used in combination with the TLS.2, a 3-wire sensor termination terminal block for the power connections and distribution.  At only 6.2mm wide, this block will terminate 6 wires in 1/3 the space of typical terminal blocks.  As a power distribution terminal block the TLD.2 mounts next to the TLS.2 sensor block and accepts the lock jumper system for connection of the negative and positive circuits to sensors.
