Be sure that the PCB is strong enough to support them. We recommend dual-side through-hole PCBs to reduce solder cracking from heat stress. Do not impose excessive external force on the G7J in the horizontal or vertical directions when inserting the G7J to the Faston receptacle or pulling the G7J out from the Faston receptacle. Do not attempt to insert or pull out more than one G7J Unit together. Mount the G7J with its test button facing downwards. The Relay may malfunction due to shock if the test button faces upwards. Be careful not to press the test button by mistake because the contacts will go ON if the test button is pressed. If the normal mounting direction is not used, carbides or powder from contact abrasion that results from load switching will accumulate inside the Relay. If the Relay is used past its endurance in this state, insulation failure between circuits of different polarity or Relay burning may occur. Be sure to use the test button for test purposes only. The test button is used for Relay circuit tests, such as a circuit continuity test. Do not attempt to switch the load with the test button. Do not solder the tab terminals. Terminal #250 terminal (6.35 mm in width) Receptacle AMP170333-1 (170327-1) AMP170334-1 (170328-1) AMP170335-1 (170329-1) Housing AMP172076-1: natural AMP172076-4: yellow AMP172076-5: green AMP172076-6: blue Note: Numbers in parentheses are for air feed use. If a voltage is applied to the coil, the test button will retract in an ON state (i.e., an excited state). Operating Coil Micro Loads Internal Connections of Coils DC coil The G7J is used for switching power loads, such as motor, transformer, solenoid, lamp, and heater loads. Do not use the G7J for switching minute loads, such as signals. Use a Relay with a bifurcated contact construction for switching micro loads, in which case, however, only SPST-NO or SPST-NC output is obtained. A2 Soldering PCB Terminals A2 Be sure to solder the PCB terminals manually only. In the case of automatic soldering, some flux may stick to the test button and the G7J. As a result, the G7J may malfunction. The G7J is not of enclosed construction. Therefore, do not wash the G7J with water or any detergent. Connecting A1 AC coil A1 If a transistor drives the G7J, check the leakage current, and connect a bleeder resistor if necessary. The AC coil is provided with a built-in full-wave rectifier. If a triac, such as an SSR, drives the G7J, the G7J may not release. Use the Power MOS FET Relay in this case. Refer to the following diagram when connecting a wire with a screw terminal to the G7J. 7.6 8.8 7 4.5 M3.5 Allow suitable slack on leads when wiring, and do not subject the terminals to excessive force. Tighter the terminal screws with torque 0.78 to 1.18 N·m. Loose screws result in disconnection of lead wire, malfunction or fire. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
