Designed primarily for applic ations involving fast-switching semiconductors, the FN 9246 is an ideal high performance EMI suppression solution for use whenever space is at an absolute premium. Eight current ratings span from 1 to 20A. The 16A and 20A versions are the largest, at 35 x 75mm, with lower current versions at 30 x 47mm. The series has much higher inductance and X capacitor values. Schaffner EMC Inc, 9B Fadem Rd, Springfield, NJ 07081. 800-367-5566. http://www.schaffner.com Circle 434.
The Thinswitch limit switch verifies component position before sequential operation can occur, protecting operators from injury and preventing damage to equipment. Applications include injection molds, trash compactors, paper balers, packaging machines and various reciprocating machinery. The UL Recognized and CSA Certified switching element is rated 250VAC 7A resistive, with a life exceeding 10 million cycles. Burger Engineering Inc, 1700 E 123th St, Olathe, KS 66061. 800-764-3518. Circle 432.
Featuring a solid cast stainless CF-8M housing with stainless steel trim and shaft bearing, the Watchman-II VPT includes an indicator environmentally sealed against fogging and entry of contaminants. The compact, NEMA 4X enclosure is designed for use in extremely corrosive environments. The basic unit includes two 1/2-in. NPT conduit entries, two 15A switches and a black/yellow indicator. Moniteur Devices Inc, 36 Commerce Rd, Cedar Grove, NJ 07009. 973-857-1600. Circle 433.
Measuring just 8- x 5-in., with a depth less than 1 in., this miniature keyboard is plug-and-play ready for OEM applications. Dual function keys provide 104-key functionality from the 68-key QWERTY layout, and NEMA 4-rated silicon keeps the keyboard resistant to dust, water, oil and solvents. Options include the Industrial Mouse, backlighting, keyboard mouse emulation and custom legends.

Hall-effect speed sensor. The HE615300 Geartooth Speed Sensor offers zero speed-sensing capabilities via a single sensor coupled to self-calibrating peak-to-peak circuitry. Optimal performance is achieved with targets of high magnetic permeability, such as low-carbon steels. Uses include sensing of web speed or power transmission gears, conveyor speed and position, and other similar shaft encoding.
