|
| |
Your choices are...
|
|
|
| |
Single Feed Through
|
|
Type of basic terminal block used for wire-to-wire connections where the wire feeds through one side and out the other. Single feed through terminal blocks have one input and one output contact.
|
| |
Dual Level
|
|
Also called two tiers, these terminal blocks have two levels of contacts. They are used to save space and simplify wiring.
|
| |
Dual Level Bridged
|
|
Also called double level and two tiers, these terminal blocks have two levels of contacts. They are used to save space and simplify wiring. Bridged terminal blocks use a "bridge" to connect one level to another for increased circuit flexibility.
|
| |
Three Level
|
|
Also called three tiers, these terminal blocks have three levels of contacts. They are used to save space and simplify wiring.
|
| |
Three Level Bridged
|
|
Also called three tiers, these terminal blocks have three levels of contacts. They are used to save space and simplify wiring. Bridged terminal blocks use a "bridge" to connect one level to another for increased circuit flexibility.
|
| |
Ground Circuit Terminal
|
|
Interchangeable with standard block. These units can be inserted as needed. Permits grounding of components that run to a specific piece of equipment.
|
| |
Disconnect or Switch Block
|
|
This type of terminal block allows a circuit to be easily disconnected without removing any wires. A knife switch uses a lever type of control handle to disconnect the circuit. A sliding link disconnect uses a link that can be slid to the side to disconnect the circuit. A plug disconnect has a removable plug to disconnect the circuit.
|
| |
Fuse Holder or Fuse Block
|
|
When a short circuit occurs, only the portion of the circuit connected to this block is affected. This can also be a disconnect block if dummy fuses are inserted instead of standard fuses. A light gives visual indication of fuse condition. Also called circuit protection blocks.
|
| |
Thermocouple Block
|
|
For connecting to thermocouples. Provides consistent metal type connections for thermocouple sensors to measure temperature.
|
| |
I/O Block
|
|
Provides communication between a controller, usually a PLC or IPC, and some type of sensor level devices.
|
| |
Sensor / Actuator Block
|
|
Handles three-wire or four-wire proximity sensors, three- or four-wire photoelectric sensors, or any other type of three- or four-wire device. Also enables high-density terminations.
|
| |
Electronic Circuit Block
|
|
Terminal block that provides electrical circuit functionality such as rectification, voltage indication etc.
|
| |
Transformer Terminal Block
|
|
Transformer terminal blocks are designed to be mounted on coiled bodies. Mounting type can be direct mounting on coil bodies with integrated mounting chambers as well as for snapping onto aluminum transformer rails. These devices serve the purpose of adapting coil ends to screw or push-on tab connections to facilitate connection of the devices or system equipment to be supplied with power.

Power Distribution Block
|
|
Terminal blocks specifically designed for the power distribution industry.

Mounting Options
|
|
|
| |
Your choices are...
|
|
|
| |
Universal Mounting Foot (Rail)
|
|
Designed for mounting on DIN and other rail types, the body has a mounting foot that enables the terminal block to be snapped on and off the mounting rail without being weakened. Also called multi-rail mounting.
|
| |
15 mm DIN Rail
|
|
Designed for mounting on a 15 mm DIN rail.
|
| |
32 mm DIN Rail
|
|
Designed for mounting on a 32 mm DIN rail.
|
| |
35 mm DIN Rail
|
|
Designed for mounting on a 35 mm DIN rail.
|
| |
Panel Mount
|
|
Designed for mounting on panels.
|
| |
PCB Terminal Block
|
|
PCB is the abbreviation for printed circuit board. PCB, or PC terminal blocks are designed to be mounted to a circuit board. They either have integral pin terminals for mounting through holes on the circuit board or can be "plugged" into pins on a pin strip that is mounted to the circuit board.

Termination Options

|
|
|
| |
Screw Clamp
|
|
A screw is the simplest method of connection: A screw is used to tighten the wire against the current bar with or without a pressure plate. This is the classic, industry standard, wire connection. Widest choice of blocks. Screw clamp technology has been integrated into many other functional terminal blocks including fuse holders, electronic component holders, signal conditioning modules, surge protection modules, and more. Screw clamp technology offers the widest range of products for 24 AWG to 600 MCM wire applications. The reliability and quality of the connection is demonstrated by compliance with all worldwide standards including UL, CSA, and IEC.
|
| |
Spring Clamp
|
|
Spring clamps need a tool to open. The clamp closes on the wire to provide dynamic clamping. This extra holding action withstands vibration. Spring clamp technology is especially suited for top entry connections. The top entry of the wire into the spring block allows use where space is limited, for example, between the terminal block and nearby panel components such as wire duct. The spring block technology was developed approximately 20 years ago to offer an alternative to the then only screw clamp technology for easy field and factory wiring. The wire is retained in the clamp by the force of the spring that pushes the wire against the connecting bar as shown in the illustration. Spring technology is used in applications where small wire sizes are being used, generally below 10 AWG. The reliability and quality of the connection is demonstrated by compliance with all worldwide standards including UL, CSA, and IEC.

| |
Insulation Displacement (IDC)
|
|
A type of connection in which the insulated wire is pushed down between two sharp bladelike pieces of metal so that the conductor touches the connector and there is no exposed bare wire.
|
| |
Tab Connection
|
|
Tab terminals, also referred to as spade or blade terminals, are designed to be inserted / removed rapidly without the need for soldering.
