It draws less than 20 mA (excluding load) and provides two open-collector outputs: MA3-4 uses complementary NPN transistors (one normally open and one normally closed) with up to 150 mA per output and a saturation voltage under 0.5 V at 10 mA; MA3-4P provides complementary PNP outputs with identical current capability and switching behavior. The module features a top-mounted gain control and a Banner Alignment Indicator Device (AID) LED to indicate signal strength, is epoxy-encapsulated in a VALOX housing with gold-flashed pins, and can connect via the optional RS8 socket or be mounted directly to a PCB. It operates from -40 to +70 C and supports sensor leads up to 30 ft (9 m). Response time is 1 ms ON\/OFF with ~0.3 ms repeatability. This device belongs to Banner’s MICRO-AMP system and, when used with Banner remote sensors, yields the same optical response as larger CM Series modules; note that MA3-4 is obsolete and may have newer replacements in Banner’s current lineup.\u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"New","offer_id":51676562358574,"sku":null,"price":507.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_05445135-db91-46a6-b9cc-50521e63bf8f.jpg?v=1769551498","url":"https:\/\/plgautomation.com\/products\/banner-engineering-ma3-4-modulated-photoelectric-amplifier","provider":"PLG Automation ","version":"1.0","type":"link"}
