An object used to retain air pressure, water, hydraulic fluid or oil in a vessel. In the Tol-O-Matic product line, seals are made of an elastomer, which is any of a variety of synthetic rubber compounds.

Sealing Band

The stainless steel strip which is part of Tol-O-Matic’s patented band retention system, the internal band.

Shielding

The practice of confining the electrical field around a conductor to the primary insulation of the cable by putting a conducting layer over and/or under the cable insulation. (External shielding is a conducting layer on the outside of the cable insulation. Strand or internal shielding is a conducting layer over the wire insulation.)

Shock Absorbers

A self contained hydraulic device commonly used on rodless cylinders, rodless slides and rod cylinder slides to decelerate heavy loads at high velocities.

Signal

The event, phenomenon, or electrical quantity that conveys information from one point to another.

Single-Acting Cable Cylinder

Cable cylinder that applies force in one direction and uses gravity (generally) to return to home position.

Single End Porting

Single end porting simplifies air hook up, allows running air lines to just one end of the actuator. Unless otherwise specified single end porting is factory installed on the right side of the actuator. Available for the BC3 and BC4.

Snap-In Seal®

A patented method of installing seals in cable cylinder heads without using tools. It includes a plastic washer, which, when pulled into a cable cylinder head cable port, snaps into a groove and holds the seal arrangement in place.

Solid State Devices

Electronic components that control electron flow through solid materials (e.g., transistors, diodes, or integrated circuits).

Surge

A transient variation in the current or potential at a point in the circuit.

Switch Magnets

Located on the carrier or piston magnets are needed for switches to sense position of carrier. On the BC3 and BC4 the switch magnet is a standard feature, attached to the piston. On the BC2 and LS the switch magnet is only included if switch is ordered. Magnets are easily inserted into carrier for field retrofitting.

Switch Magnets Dual

The BC2 optionally can have dual switch magnets, one on each side of the carrier.
