Dial Indicators
• Back plunger type dial indicators are suitable for mounting onto leveling machine tool tables or inspection jigs, and for use in situations where standard dial indicators are difficult to read. • Models 1960A and 1961A , which use proprietary Mitutoyo shock-proofing mechanism, have excellent durability and shock resistance.

Note 1: Contact point (standard accessory) for all products in this page has a role as a top dead point stopper. When replacing it with an optional contact point with a connector not exceeding ø7 mm in outside diameter, insert a washer (with ø7 mm outside diameter, ø3 mm inside diameter, and approximately 0.5 mm thickness) above the contact point. Note 2: Refer to pages F-63 to F-68 for details of contact points.
