PEPI^® Model V thermal protectors feature a unique V-shaped, ultra-small plastic case allowing them to fit neatly between AA battery pack cells. This family of snap-action thermal protectors offer both overcharge and short-circuit protection. Their low internal resistance draws minimal power from battery packs and cases are isolated from the circuit maximizing reliability. Read more...

The PEPI^® Model FC-P2D is an ultra-small circuit protector. The plastic case insulates it from the circuit and ambient heat to counter nuisance tripping. Despite the small size, it provides circuit protection on loads as large as 12 amps 125 VAC inductive circuits. These devices are part of the PEPI^® Valstat^™ Series™ making them readil...

Limited production runs and the need for high reliability puts pressure on circuit protection devices used in specialty appliances aimed at luxury markets. The high quality design of PEPI^® thermal controls, and their ability to be customized to better fit the needs of different applications, are key to their industry-leading reliability. Read more...

Circuit reliability concerns escalate as loads elevate because the consequences of failure are more catastrophic. For this reason, PEPI^® Thermal Controls are designed to improve circuit safety when loads are as high as 50 amps on 120 VAC inductive loads and 20 amps on 240 VAC resistive loads. This makes them an ideal safety component on large motors, transformers and batte... Read more...

Contacts are the critical thermal control components most prone to tarnish and wear, so bigger is better. Contacts used in PEPI^® thermal controls offer more surface area to maintain positive contact when slightly misaligned or worn from repeated use. PEPI^® contacts are also made of coin silver to resist tarnishing that impedes electrical flow in closed circu... Read more...

An alternative worth considering before machining a keyway

Connecting a pulley, sprocket, gear or coupling to a shaft? A keyed connection may be familiar, but a keyless shaft locking device offers another option, particularly when positioning, adjustment or removal matters.

Clamping cones secure the hub to the shaft, allowing its position to be set before tightening.

The Output Shaft Carries more than Driving Torque

A planetary gearbox may meet your torque and speed requirements, but what other loads will its output shaft carry? Radial and axial forces also need consideration when assessing suitability and bearing life.

Before selecting a gearbox, check:

• Required output torque and speed.
• Operating du...
