A snap of the lever secures the connection of the sensor head cables on the SU-7 amplifier. It is no longer required to strip the wire insulation. Further, the exclusive stripper (accessory) can be used to easily peel off the sensor cable outer sheath. 1 Aligning with the mark to be detected, press the ‘ON’ button. 1 Strip the cable sheaths with the exclusive stripper. 2 Insert the wires into the holes. 3 Flip up and lock the lever. Exclusive stripper (Accessory) 2 Aligning with the background, press the ‘OFF’ button. Caution: The outer fluorine sheath of the chemical resistant type sensor head, SH-61R, cannot be cut off with the dedicated stripper. Nine advanced functions for versatile sensing 1 Limit sensitivity setting Thickness: 10 mm 0.394 in Installation space can be greatly reduced as the SU-7 amplifier is just 10 mm 0.394 in thick. 31.5 mm (1.240 in) 67mm (2.638 in) 10 mm 0.394 in All models Sensitivity for detection of minute differences can be set by the press of one button without an object being present. All models 2 Sensitivity shift The set threshold level can be shifted from the center towards either ON or OFF level. 3 Remote sensitivity selection SU-79 The amplifier stores four channels of sensitivities. They can be selected by the remote inputs. SU-77 4 Remote sensitivity setting The sensitivity can be adjusted from a remote place. SU-75 5 External synchronization The timing for sensing can be specified by an external input. 386 SU-75 6 Test input (emission halt) Convenient for start-up inspection. 7 Sensitivity margin indication All models The number of blinks of the stability indicator indicates the degree of sensitivity margin. 8 ON-delay / OFF-delay timer SU-7 SU-77 SU-79 SU-7J The timer can be selected for either ON-delay or OFF-delay of 0 to 5 sec. All models 9 Interference prevention Two sensor heads can be mounted close together.

Wiring • Trim the cable ends The stripper SU-CT1 helps you to cut the cable and peel the sheath off the cable. To cut the cable or to strip the sheath, insert the cable into an appropriate hole as shown in the right figure and press the blade down. Holes for cutting the cable Holes for stripping the sheath Note: The outer fluorine resin sheath of SH-61R cannot be peeled off with SU-CT1. • If the attached sensor head cables need to be extended, use two single core shielded cables of at least equivalent quality. If a joint terminal or connector is used for extension, refer to the figures below. (The shielded extension cable must be of "1.45 mm "0.057 in outer diameter.) Connection with joint terminal M3 (length 12 mm 0.472 in) screws with washers Sensor head mounting bracket MS-SS3-1 (Optional) Beam- Beamemitting receiving The beam-emitting cable cable cable and the beam-receiving cable should be separated from each other as much as possible.

Caution • After locking, if the lock is released and the cable is removed, it can be locked again, as it is, only once. If the locking is repeated three times or more, repeat the process from Step 2. If the cables are locked and released repeatedly, note that the cable ends may break, resulting in a bad connection. • If there is a shred of the cable left inside the cable inlet, remove it before connecting the sensor head cables. Turn the amplifier upside down, and tap it Broken cable end around the holes. If the shred still remains, peel the bottom seal Seal Seal off the amplifier, and drop it out.

The setting level is the same as for limit sensitivity setting. However, since the operating level is shifted after the normal sensitivity setting, output operation is selectable.
